High qualitied synchronous motors for machines & cars

W22 BLDC Motor & Controller adopts most advanced motor controlling technology, with full functions to be realiable and operation-steadily. The system has been improved at efficiency and make realize re-brake, skid backward proof, false indication, thus improving range of one charge and safety performance. It is widely used in industrial power solution.


Main futures:
* High performance micro processor. precise speed and torque output,high efficient, smooth and low noise level.
* electric commutation: high frequency PWM chopper modulation mode and continous stepless speed regulation.
* Programmable control function. User can modify paramters by hand-programmer. Flexible parameters setting can be customised for kinds of requirements.
* Fault diagnosis and multicolors LED indication lights to show operation situation and faults types clear at a glance, convenient after-sales engineers call to solve fault, reduce the cost of after-sales service.
* Adopted synchronous freewheeling technology to make higher efficiency.
* Multi power-recycle start modes. Such as start at brake signal, commutation
* RS-232 communication. Can be connected with external display terminal.
* Temperature protection. At controller overheating current drops linearly,not suddenly shut off, to effectively guarantee driving safety.
* Low voltage and overvoltage protection. Effectively protect the battery and controller, prolong service life.
* Adjustable controller input power limit. It can avoid the battery output current is too big so that damages battery and circuit, effectively protect battery and safety of the circuit.
* With new design of power structure and SMD process. Make high reliability and electromagnetic compatibility.
* Large current adopts aluminum column outlet method; control wiring uses press-type of connection. Make connection more convenient, reliable and safe.
* Reverse speed limit. The speed is reduced when vehicle back up for security.


1-50KW at different voltage and speed can be customised following our RD process.
