Solution

The starting torque of a three-phase induction motor can be increased by:

  1. Increasing the supply voltage: The torque of an induction motor is proportional to the square of the supply voltage. So, if the supply voltage is increased, the starting torque will also increase.

  2. Using a higher number of poles: The torque of an induction motor is also proportional to the square of the number of poles. Therefore, using a motor with a higher number of poles can increase the starting torque.

  3. Using a motor with a larger rotor diameter: The torque of an induction motor is proportional to the square of the rotor diameter. Therefore, using a motor with a larger rotor diameter can increase the starting torque.

  4. Using a motor with a larger rotor length: The torque of an induction motor is proportional to the rotor length. Therefore, using a motor with a larger rotor length can increase the starting torque.

  5. Using a motor with a higher slip: The torque of an induction motor is proportional to the slip. Therefore, using a motor with a higher slip can increase the starting torque.

  6. Using a motor with a higher rotor resistance: The torque of an induction motor is proportional to the rotor resistance. Therefore, using a motor with a higher rotor resistance can increase the starting torque.

  7. Using a motor with a higher stator resistance: The torque of an induction motor is proportional to the stator resistance. Therefore, using a motor with a higher stator resistance can increase the starting torque.

  8. Using a motor with a higher stator inductance:
