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.
