BLDC motor (DC Motor) benefits in the speed control is relatively simple terms, the size of the control voltage only has control of speed, but the motor should not be in such high temperature, flammable and other operating environments, and because of the need to brush motor As a current converter (Commutator) components (brush motor), so they need regular cleaning of the friction generated by carbon brushes dirt. The brushless motor as compared to a brush, brushless motor because less carbon brush and shaft friction so more energy is relatively quiet. Made more difficult, the price is higher. bldc motor controller (AC Motor) can at high temperature, flammable and other operating environments, and do not regularly clean up the brush of the dirt, but in the more difficult to control speed, because speed control bldc motor controller must control the frequency of alternating current (or use of induction motors, with the increase in internal resistance in a manner that the same lower frequency AC motor speed), control the voltage will only affect the motor torque. General civil motor voltage 110V and 220V and other two, in industrial applications as well such as 380V or 440V type.

Q: We received two parcels. Finally managed to get it all working. the lcd display does not go over 10 mph ? can you think why
A:Do you make you motor “reverse”? If you make the three button switch to be “R”, motor will be reverse, the speed is slow. Make to “L”, motor will be forward.
Q: I have disconnected the three button switch and now seems to be working. the display when the bike is in use does not go above 10 mph. does the display after you have set the mph/kmh mean ? It says p1, p2,p3.p4 and p5. what are the correct settings for these ?
Your bike can reach 40 mph without load,we test it.Even if you ride,still can reach about 35mph.
Please set the wheel size to be “26”
* Power on,turn on LCD,then press “up” and “down” button for 2 second together.
1. Then max speed will flashing. Make it to be max 72kmh.
2. Then “kmh or mph” will flashing.Press “up” or “down” to shift from “kmh” to “mph”.Then press “ON /in the middle of button” to done setting.
3. Then “wheel size,8,10,12,14,16,18,22,24,26,700 or 28” will flashing.Press “up” or “down” to shift.Make it to be “26” Then press “ON /in the middle of button” to done setting.
After setting these 1,2,3. Then press “ON /in the middle of button” for 2 second.It will save these setting.
Try it again.
Don’t set P1,P2,P3..
New LCD advanced manual enclosed.
Please set it as below:
P1: 46
P2: 0
P3: 1
P4: 0
P5: 15
Q:Finally got it all sorted out.The bike conversion kit works really well and is fast and powerful.Thanks.
bldc motor controller and its classification and criteria
bldc motor controller and its classification and criteria:
bldc motor controller is mainly linear motor, it is a direct conversion of electrical energy to mechanical energy into linear motion, without any intermediate conversion mechanism of transmission.
bldc motor controller structure can be made as needed Flat, cylindrical or disk-based and other types, it can use AC power, DC power supply or other pulsed power supply to work. bldc motor controller can be in a few seconds to a few thousand kilograms of helicopter pulled several hundred kilometers per hour, it operate in a vacuum, its highest speed up to several thousand kilometers. In the military, people use it made of a variety of guns, and tried it for missiles, rockets; in the transport industry, people use bldc motor controller is made up of more than 500km per hour maglev train; in the industrial area, bldc motor controller is used in the production line for delivery, and a variety of horizontal or vertical movement of a number of mechanical devices. bldc motor controller and have a high-speed, high-thrust features, it also has a low speed, the other fine features, for example, stepping linear motors, it can be done step for the 1μn accuracy, therefore, bldc motor controller has been applied to Many sophisticated equipment, such as the computer’s head drive, camera shutter, automatic plotter, medical equipment, aerospace equipment, a variety of automation equipment, etc. In addition, bldc motor controller is also used for a variety of civilian installations, such as doors, windows, tables, chairs moving, door locks, electric curtains opening and closing, and so on.

S mine fan bldc motor three frequency high-voltage electric tricycle china application
Author: Xu Yingsheng Wang Jihao Sunyan Bo Gu Wei
Abstract: A crystal by controlling the frequency control to achieve a level, no level adjustment in the electric tricycle china installation and large-scale mine owners bldc motor in the application.
Keywords: three-conversion,electric tricycle china installation
Specificity due to the production of coal, the mine ventilation system related to mine safety in production, so the ventilation system in the coal production has a pivotal position. As long supply line, starting pressure drop, maximum protection devices for safe and reliable start-up and standby bldc motor starter switch, the top priority is to enhance the system reliability. Yangquan Coal Mine in NZ in November 2006, new investment and operation of the main fan bldc motor for the GAF-type axial bldc motor (check the bldc motor by the largest coal mine in Asia through bldc motor controller). The main fan motor 10KV 5000KW bldc motor asynchronous motor. In order to better address the project encountered in starting the impact on the grid, and the problem of load impact, the system used by the Liaoning Rongxin Power Electronic Co., Ltd production of three self-developed high-voltage electric tricycle china frequency equipment.
1, electric tricycle china several Starting device
Divided by the motor starter schematic: 1, reduced voltage starting methods. Traditional vacuum motor starting methods are Y-Δ start, decompression starting autotransformer, reactor start-up and so on. These methods belong to a class start decompression start, there are obvious shortcomings, the process of starting a secondary impact of current. The current high-pressure common way for liquid resistance starter starter, SCR series decompression start. 2, variable frequency start method. With the development of IGBT technology, high frequency voltage levels and larger capacities, but because of the price factor has restricted its development.
Rongxin Power Electronic Co., Ltd., on the basis of the SVC successfully developed three high frequency electric tricycle china, it has three characteristic frequency stepless regulator.
2, three frequency high-voltage electric tricycle china technical principles and characteristics
High-voltage soft-start power supply and motor in series between the main circuit shown in Figure 1.
Figure 1 Main circuit diagram
Three frequency high-voltage soft-start technology, the first SCR in series, then by controlling the conduction angle of SCR to achieve a level FM, and non-polar voltage regulator functions. Starting early by controlling the valve in the SA, SB, SC was to achieve a turn-on frequency 12.5HZ, the motor of 1 / 4 the rated speed when the control valve SA, SD, SE switch to 25HZ, the motor to achieve 1 / 2 rated speed, through the control valve SA, SB, SC to complete the full range of the switching process, and ultimately reach the rated speed, the bypass is closed off electric tricycle china trigger pulse to complete the starting process. Throughout the starting process in the three frequency points, while adjusting the frequency, change the output voltage to maintain constant voltage to frequency ratio, so that you can ensure that the entire starting process, the starting torque to keep the rated torque of 80 -90%, while the starting current can be controlled at about 2 times the rated current. Starting torque, starting current, is a three-frequency high-voltage electric tricycle china’s largest technical characteristics.
3, S miners fan motor in the practical application.
Yangquan Coal Mine S is a new mine, it’s power capacity is 35KV, 10000KVA, because the grid is responsible for the underground, Inoue electrical equipment supply, so the grid is relatively small margin, in order to ensure the process does not affect the start Other devices running on the main fan starting current requirements are very strict. And because it is located in the high-gas area, which uses negative pressure was high winds axial bldc motor (two-stage fan is currently Asia’s largest mining axial bldc motor), the main fan motor power of 10KV, 5000KW. Throughout the starting process, showing the starting torque, starting current, a smooth start, the advantages of starting a short time. Measured data in Table 1.
