Abstract
A control device for an electric motor of a cooling fan for the radiator of a motor vehicle has a control transistor connected to the motor, and an electronic control unit for controlling the speed of the motor. The control unit controls the transistor in such a manner as to limit the current flowing in the motor to a predetermined value when, by effect of the load conditions of the motor and the voltage applied to the motor, the current in the motor tends to exceed the predetermined value.
