  • Rotational speed control device for an electric motor
    Patent number: 6243532
    Abstract: A speed control device for an electric motor fed by a direct voltage source, the device comprising a controlled switch by which the motor voltage is alternately switched on and off under the control of a modulated switching pulse sequence. The switching frequency is higher than the frequency corresponding to the time constant of the electric motor. The switched motor voltage is regulated to a voltage set value corresponding to a desired motor speed by influencing the modulated switching pulse sequence.
