  1. These motors have high efficiency due to the absence of rotor current.
  2. Pulse Width Modulation
  3. It is a normal DC motor with built-in servo drivers and gearboxes.
  4. consists of a permanent magnet.
  5. is an electric motor driven by an alternating current (AC)
  6. controlled by PWM (pulse width modulation).
  7. Deal with higher current surges
  8. Not intended for high current surges
  9. Large torque to weight ratio
  10. used in variable-frequency drives to control the torque,of three-phase AC motors
  11. is the stationary part of a rotary system
  12. converts electrical energy into mechanical energy, causing a rotary movement
