Cooling Fan Motor Controller
Cooling Fan Motor Controller is an all-in-one solution developed to cool the heat of the engine which has been transferred to the radiator of vehicle.
Detailed Description
Cooling Fan Motor Controller is an all-in-one solution developed to cool the heat of the engine which has been transferred to the radiator of vehicle.
As a built-in type(integrated with the device), it achieved the control circuit optimization.
It applies algorithm for precise control of position/speed without motor position sensor(high efficiency, low noise).
The logic ensuring high reliability is implemented.
