Abstract
The present invention refers to an air-cooled motor controller for controlling electric motors, comprising a heat-sink and a variable fan for cooling passive and active components of the motor controller by means of an air stream generated by the fan. The invention is directed towards a fan control means and a coupled fan control method for controlling the speed of the fan of the motor controller in response to the losses in both passive and active devices inside the motor controller.
