Abstract

Device for controlling the speed of a cooling fan driven by a dc motor as a function of the temperature perceived in an environment, in particular for the control of the speed of the electric fan associated with the radiator of a motor vehicle as a function of the temperature of the cooling liquid, characterized in that it comprises: a temperature sensor intended to provide an electrical signal indicative of the perceived temperature, and in particular the temperature of the engine cooling liquid; a power switching amplifier circuit and connected between the fan motor and the supply voltage source of such motor; and a control circuit connected between the temperature sensor and the power circuit and intended to supply such a power circuit with a rectangular wave command signal of fixed frequency and with variable duty cycle as a function of the temperature signal provided by said sensor, in such a way as to cause corresponding variations of the average value of the voltage supplied to the motor and, therefore, of the speed of rotation of such motor.
