Disclosed is a method for controlling an electric motor (10) fed by a constant voltage supply system (14, 20), especially a method for controlling a fan motor which is fed by a motor vehicle power supply system using pulse width modulation and which can be connected to the constant voltage supply system via an actuator (18) in the electric circuit of the motor. According to said method, the supply voltage (UM) of the motor (10) is timed according to a predefined characteristic curve substantially independently of sudden changes in the supply voltage (UB) of the constant voltage supply system.
