Speed Controlers

  1. There are advantages of using electronic speed controllers. They provide soft starting which is combined with step-less speed control and the use of an inexpensive standard squirrel cage motor

    However there are disadvantages in using such technology

    State two of these:
    • -Higher cost
    • -Possibility of interference voltages
  2. Explain the difference in the switching component between half wave and full wave speed control
    In the half-wave, speed control is obtained using a diac.

    In full-wave however, speed control is reached by using a triac
  3. When we control a universal motor with a centrifugal governor we obtain a constant speed machine. What is meant by this term?
    This means the speed does not vary with torque. The steady-speed characteristic may be obtained at other speeds by adjusting the governor
