1. A motor apparatus comprising:

  • a DC motor comprising a stator and a rotor;

    an AC to DC converter configured to receive an AC power input and to convert the AC power input to a DC power;

    a PWM signal generator configured to generate PWM signals;

    a switching circuit configured to generate a PWM switched power using the DC power and the PWM signals, and to supply the PWM switched power to the DC motor; and

    at least one control circuit configured to detect irregularities in the AC power input and to send a control signal to the PWM signal generator, wherein upon receiving the control signal the PWM signal generator is configured to stop generating the PWM signals and then restart generating a new set of PWM signals.
