Advantages and disadvantages of Induction Motors


  • It is simple and rugged in construction
  • It is relatively cheap
  • Induction motors require less maintenance
  • Induction motor has high efficiency and reasonably good power factor
  • 3-phase induction machines are self starting


  • Induction motors are essentially a constant speed motor and its speed cannot be changed easily
  • Its starting torque is inferior to dc shunt motor.
