Three years ago, leaf motor started to design controllers,manufacture controllers,test controllers,modify and re-test. Day by day. three years past,compare with other controllers,leaf three mode controllers are the best.
In market,there are square wave, sine wave, two kinds of brushless controllers that drive brushless with hall sensor motor.Every one knows,hall sensor is electronic component.It works in the rotating rotor.It’s easy to be broken.
If one hall sensor is broken, the electric bike can’t work. Need to replace hall, but it’s very hard to replace hall.Not easy. Replace the whole of winding rotor, it’s too expensive.
In past,leaf sell KT controller,met hall sensor issue, should replace the whole of winding rotor to customer.
The price for one hall sensor is less than $1USD
But, the whole of winding rotor over $100USD includes shipping cost.
Replace winding rotor waste too much.
Sine 2019,leaf motor started to manufacture theirselves controllers.
Leaf Brand New electric motor controller with Sine wave, Square wave, No hall, three modes compatible.
What are three modes?
* First mode: Sine Wave Status – Motor without noise,Very quiet !
If one of motor hall sensor is broken, controller still can work in Sine Wave Status.
* Second mode: Square wave Status – Motor with a little noise, < 60db, speed is about 8% faster than Sine Wave Status. If two of motor hall sensors are broken, controller can work in Square Wave Status. * Third mode: No hall Status - Motor with a little noise, < 60db, speed is about 8% faster than Sine Wave Status. If all of three hall sensors are broken, controller can work in No hall Status. If your motor's hall sensors are broken, don't need to replace hall sensors. Just use this controller that can recover your motor to work. If you don't know how to match motor wires to controller. Just plug two blues together, controller into learning status and looking for correct working way. After 1-2 seconds, it can find correct working way,then disconnect these two blue wires' plugs. From now on,it always works with this kind of correct way.
