In a synchronous motor, pull-in torque refers to:
- 1The maximum torque developed during the process of rotor synchronism when approaching synchronous speed.
- 2The torque produced when the motor operates at speeds above synchronous speed under load.
- 3The torque required to bring the rotor into synchronism from near-synchronous speed.✓
- 4The maximum torque that can be sustained by the motor under steady-state full-load operating conditions.
Correct answer
The torque required to bring the rotor into synchronism from near-synchronous speed.
