about 1000w and 1500w electric hub motor

Posted by on March 15, 2025 No comments

I am part of a team what will be competing in an ECO marathon challenge. That means we will be building a vehicle that will compete with other teams. The most efficient vehicle will win the prize!

We are building a three wheeled car, driven with a hub motor used as mid-drive motor. I have been a member of the Endless-Sphere group for very long and knew that the Leaf 1500Watt hub motor is the best in therm of efficiency.

So my question is, is it possible to get the hub motor for a cheaper price (free shipping) in exchange for some stickers we will put on our vehicle? Let me know if you have any interest in sponsoring our build/team! If you have any questions feel free to email me back, I will get back at you as soon as possible!

Could you tell us what winding options are available for the 1000Watt electric bike motor (Item ID #LBM481KRNC) and the 1500Watt electric bike motor (Item ID #LBM481500RNC).
We are looking to find out what hub motor is the most efficient on a voltage of 48Volts.

So could you tell us the max RPM, per winding option (1000watt and 1500watt) at 48Volt?

We would like to compare each different electric bike motor(1000/1500watt and different winding options) in a simulator.
The simulator we are using to compare each hub motor is an online simulator

To simulate all the different electric bike motor options and windings we need some parameters from each motor 1000watt and the 1500watt. Is it possible to provide us these motor parameters, so we can run a simulation on the 1000watt motor with different windings and on the 1500watt with different windings?

What would be the max RPM of a hub motor with those options (20 inch 1000w cassette and disk brake)?
And what would be the turn count?
Thickness of laminations? Will it have the same efficiency as the 4Turn 1000watt motor?

fat electric bike motor

With regards to this product 20 inch 48v 2000w rear hub motor beach snow fat tire bike conversion kit.Will my existing battery and brakes work?I have a 48V 14.5 AH battery and hydraulic brakes.
What about hills? Will it work for that too? Also will I be able to use a 52v electric bike battery on that hub motor controller?
Also my current bike, the display has buttons for me to turn on my headlight and tail light, would your system be compatible to turn on and off my headlight and tail lights?
Does that switch plug and play or do i have to splice into the lights and into the controller? I want to use the same battery.
Do you sell just the motor? Maybe I can just plug it into my existing harness and controller?
Also question peter, I heard geared hub motors have more torque off the line than direct drive gearless?

Your 48v 14.5ah battery can drive it work on flat road.
Also,you can use your hydraulic brakes.
If battery’ s current is 30amp or larger 50amp.. can uphill easier..

Work with your 52v battery.
This controller work with 48v battery (min 40v to max 60v) – 52v still 48v battery, just full charged 48v battery up to 52v or more.
Have to splice into lights and battery. Very easy.
Don’t into controller.
Sell just the hub motor is okay. But not sure if works with your controller.
Recommend order motor & controller and other bike parts together.

Now nearly all geared hubs are 250w,max 500w small power.. fit for Europe
We also have these motors.

1000w,2000w geared hub motors are be eliminated by the market.
* too much noise
* low efficiency
* easy to wear gears

Nearly all 1000w,1500W,2000w,3000w e-bike,e-motorcycle use brushless gearless hub motors.

sensorless brushless hub motor at low speeds

Posted by on March 13, 2025 No comments

Sensorless brushless hub motor at low speeds and easy low-frequency vibration. Vibration frequency and load and drive performance, generally considered the vibration frequency is half the frequency of the hub motor load off. By the sensorless brushless hub motor that works the low-frequency vibration determined by the normal operation of the machine is very negative. When working at low speed sensorless brushless hub motor, generally should be used to overcome the low-frequency vibration damping phenomena, such as the increase in the damper motor, or drive on the use of segmentation techniques. AC servo motor is running very smoothly, even at low speed vibration will not occur. AC servo system with a resonance suppression, can cover the lack of mechanical stiffness, and function within the system has a frequency analysis (FFT), can detect mechanical resonance point, easy system tuning.

29 inch electric hub motor kit have problems with the cassette

Posted by on March 13, 2025 No comments

I ordered the 48v 1500W electric bike kit, with cassette.
I have problems with the cassette, the cassette is wider than where the dropouts sit around the axle.
So the hub motor wheel with the cassette on is wider than 135mm.
My bike frame is 135mm, and the website said it would fit on a 135mm frame.
When the cassette is on the hub motor wheel and i put the electric bike motor wheel on the bike, the frame grinds against the cassette when I tighten the electric bike motor wheel.
I have made it work using spacers so it spins freely, but the wheel is offset to one side now and i think my frame is spread wider. It is an aluminium frame.
Also the website said max 7 speed gear, but the cassette is for a 9 speed gear, which is also mounted now, is it suppose to be able to take a 9 speed gear, or is that an accident?
Any advice on what to do?
Also, any advice on mounting the torque arms? My frame is aluminium.

Steel is okay.But Aluminium is not good to make it larger. We worry if make aluminium frame to larger will break frame.
We recommend use 7 speed or 6 speed or single speed..

You will receive below goods:
1x pcs of 29 inch 48v 1500w rear hub motor wheel (black spokes, cassette)
1x pcs of 48V bldc motor controller (New version LCD controller)
1x pcs of LCD (New version LCD-003)
1x set of twist throttle
1x set of brake levers
1x pcs of three button switches ( use to control cruise,reverse..)
1x set of pedal assit ( It’s fit for European,if you don’t use,ONLY use throttle is okay )
Some spare spokes with plugs

——————————————-
How to set max speed?
If you feel motor is too fast,please set it to be low speed.
* Press “sw/middle button” from LCD more than 2 seconds,then LCD will display.
* Press “up & down button” together more than 2 sconds until 72 is flashing ( 72 is kmh, if you hope works 20mph / 32kmh, press “down” to be 32)
* Press “sw/middle” button one time to save,then 29 is flashing.. (29 is wheel size. Don’t set)
* Press “sw/middle” button one time to save,then kmh or mph is flashing..
* Press “sw/middle” button one time to save,then press “sw/middle” button more than 2 seconds until be back.

bike conversion kit torque performance in speed

Posted by on March 13, 2025 No comments

A major scientific and technological achievements of my 18 years I found the bike conversion kit torque performance in speed and excellent performance is due to change by the coil – in order to prove the authenticity of my first published the theory – by reversing the DC coil motors, commutation is by phase AC motor. By changing the coil to the premise of achieving the rotating magnetic field in the rotating among each of the stator magnetic pole corresponding to the current conductor always flow in one direction. Can achieve zero speed to rated speed constant torque swing speed, and there is no torque ripple, inverter can be completely eliminated, the chopper will swing popular governor world. Installed on the synchronous motor synchronous brushless DC motor commutator can not be called, is distorting the facts and the scientific community, because it is the by-phase commutation – is the AC motor, it can never find the DC motor torque performance and speed performance .

Rotating magnetic field DC motor, asynchronous motor with a rotating armature of durability and torque performance,sensorless brushless hub motor in speed performance, the performance of the perfect electric bicycle conversion kit, speed DC transformer power does not produce harmonic pollution, Speed ​​costs are very low. It can be raw materials for manufacturing into a more limited market value of commodities, will become the next golden goose, the whole industry will lead to a motor revolution. Engaged in electrical research staff to look at my town scientific and technological achievements, we know that all this is true. Is good to explore the talents of entrepreneurs to create a powerful opportunity.

Product Question of New 26 inch 48V 1000W electric bike kit – front wheel

Posted by on March 13, 2025 No comments

I’m interesting your product of New 26 inch 48V 1000W electric bike kit (Item ID #LBCK26481000FN), and having some question as below.

1. Does the kit already include regen function?
2. Is it possible to have a demonstration YouTube vedeo to show me the E-ABS regen feature?
3. Do you have magnet switch instead of Item ID #LBP002BL braking lever, because my current braking lever is an All in one type (braking lever and Shimano in one)?
4. As everyone knows the transportation cost is very high, if I can arrange the rim by myself from USA, can I replace order as following to reduce some transportation cost?
I want to make sure everything is the same as #LBCK26481000FN besides 26×1.95 inch rim. (The hub motor controller, LCD display, braking lever, three button switch, throttle etc…)

1. I always ride a route which include a lot of up and down hills, the longest one is a continuity down hill for 2 km.
it’s a 7% downhill, if you don’t use brake to reduce speed, the bike speed will be up over 45km/hr, so I always
use brake to control speed within a safety area( within 30km/hr), but after through the downhill, the rim become
very hot, it very bad situation.
That’s one of many reasons that I want to put a E-BIKE with regen braking function in my Bike.

According my description as above, is your e-bike kit suitable in this case?

4. Is the attached photo new version or old?
Do you mean that if I place order with #LBCK26481000FN kit set will get new version of LCD display?
If place order with LBC481000L 48V 1000W bike motor controller will get old version of LCD display?

When I downhill, if I release throttle and turn on the E-ABS by switch, but I don’t push the brake lever to make mechanical brake working. will bike glide freely and very fast? is the controller charging battery at this moment?

Normally when E-ABS turn on, the speed should become lower as below, is it right?

When a very long distance downhill (the same gradient),
if freely glide down (without throttle, mechanical brake, E-ABS), the invariable maximum speed is 35km/hr
when turn on E-ABS only, the invariable maximum speed should be lower than 35 km/hr, such as 25~30km/hr

looking an electric bike controller for 48V 1000W hub motor

Posted by on March 13, 2025 No comments

I am using a brushless and gearless DC hub motor that is 48V 1000W. I am looking for a suitable bike motor controller for my project.

I want to implement regen braking, cruise, reverse, setting a speed limit etc.
Will this 48V 500W controller works for this 1000W motor?

I am quite hesitant to choose the 48V 1000W brushless motor controller displayed in the web here as I am afraid that the high power may drain too much power from the battery.

I am using a 48V 10Ah battery. It should be sufficient to power the 1000W BLDC hub motor but to power both the motor and controller, it may overstrain the battery.

Can you confirm that your brushless motor controller can set max speed limit, regen brake, reverse and cruise control?
Basically, I just need to buy the three button switch and every of the button can be used to perform on/off operation such as horn, lights, cruise, regen brake etc right?
What is the default max speed limit in the brushless motor controller? Do you change and set the max speed from the LCD display, controller or both? After I set the max speed and I do not want the max speed to be change, is it possible?
The hub motor can still work with the brushless motor controller, even with or without the LCD screen right?

Do you have a similar brushless and gearless hub motor like the one that is:

1) 14″ inch – 16″ inch (including solid rubber tyre)
2) Power is at least 750 W to 1000W max
3) Can implement regen brake, cruise, reverse, set max speed limit

If you have, can I have some details for these hub motors? I need them work with LCD brushless motor controller.

Posted by on March 13, 2025 No comments

These days hub electric bike motor wheels are used for e-bikes widely. Nearly all of hub bike motor are brushless gearless. Because of low noise, high efficiency, long life are popular with riders.
Order 1 set 12″ 14″ 16″ 18″ 20″ 24″ 26″ 700c 27.5″ 650b 27″ 28″ and 29 inch hub motor kit, convert your common bike to e-bike is so easy. Directly front or rear drive your bike.
The important part is an engine -hub motor. How to build this electric bike motor?

Step 1: winding
Calculate motor power, speed RPM and confirm what type of copper wire would you use. Next is fix a rotor on the steel shelf, wind copper wires by handwork or machine. It takes about 1 hour to done it by handwork. And should use rubberized fabric to wrap your fingers. Nipping copper wires will break your fingers. If you need steel parts for your building process, then make sure you use the.

Step 2:soak paint
After winding should soak paint in order to be insulated. Use brush to put the insulated paint on the winding and make sure be soaked everywhere. It takes about 24 hours.

Step 3:press axis into rotor
Put axis into rotor winding and use a key to fix axis. Use A-B glue to paste three hall sensors on hub motor rotor, put 9-pin (three pin/each hall) into PCB and use insulated wire to fix it. Put 8-pin cable inside the axis and heavy yellow, blue, green wires to connect the three copper wires(Phase A,B,C) separately. Thin red, black wires are be weld to PCB + and – .

Step 4:paste magnet
Paste magnet inside hub, one N pole, next S pole ..one by one. More magnet, higher torque, more power. The height of our magnet is 30mm,6mm higher than other hub motor. In market,24mm high magnet only build max 500w electric bike motor. So our bike motor works at 36V can reach 750w.

Step 5:install rotor winding
Put the rotor winding inside the magnet hub, be careful hand. It has powerful magnetism.

Step 6:install two covers
Before installing both covers, we should press bearing into cover. Use hexagon wrench to tight screw nuts. When you hear “poop” from electric bike motor. That means install correctly. Done it.

Power on battery and use bike motor controller to drive this hub motor. If no any strange noise. It’s okay. You also need to make sure you have a controller that fits with the model you are working with, or else the whole thing might just fall apart.

Check your hub motor wheel – electric bike kit

Posted by on March 13, 2025 No comments

Order 1 set of electric bike kit from manufacturer-leaf motor and convert your bike to e-bike is a fun. But sometimes when we receive packages and don’t know how to handle it. Follow us:

Before install electric bike kit, we should test it first.
Step 1: Deliver your package
Spent some days on Internet, at last found leaf motor ‘s electric bike kit is the best. Ordered it and paid by paypal. Waiting for… About 3 days later, post officer knocked my door (EMS) and sign in it.
Check packing box first ,if it’s okay. Pls disconnect electric bike kit box.

Step 2: Check all goods in package
Take out 26″ hub motor rear wheel, bldc motor controller, lcd, throttle, brake lever, three button switches, speed signal wire and some connectors from packing box. Check each goods and make sure everything doesn’t have fault.

Step 3: hold on 26″ hub motor wheel
Put the hub motor wheel on your frame fork and tight both screw nuts.

Step 4: install magnet detector

Step 5: connect wires
1.Plug male 6-pin hall wires from hub motor cable to female connector from bldc motor controller;
2.Connect heavy yellow, green, blue from hub motor cable to heavy yellow, green, blue from bldc motor controller, color to color;
3.Two grey wires: connect these two wires/half speed; disconnect them/full speed;
4.Throttle connector is 3-pin that is easy to identify. Red: +4.5V, black: GND, green: Signal
5.Brake lever connector is white 2-pin.When hub motor is working, press brake lever is to cut off power;
6.Signal wire is black three pin plug that should be connected to white three pin female connector.
7.The other three pin connector from bldc motor controller is used for PAS;
8.Connect four pin lcd plug.

Make sure each wire is connected correctly. Power on battery.(Heavy red wire: +, black wire: – )Be careful,36V controller must work at 36V battery, if supply 48V DC, it will break the bldc motor controller at once.

Power on battery and press ON/OFF button on LCD one time, the LCD will light. Twist your throttle,hub motor starts to run. No strange noise…Press brake lever, electric bike kit system stops, loose it,the hub motor runs.

Please watch video .

By test electric bike kit system, we found hub motor wheel, bldc motor controller, throttle.. everything is good. Next step is that we start to convert them on bike.
