Rotor resistance control, Stator voltage control, and Direct On-Line (DOL) starting are the starting methods of induction motors.
Variable Frequency Drive (VFD)
- Variable Frequency Drive (VFD) can enable four-quadrant operation of an induction motor. This means the motor can be controlled in both forward and reverse directions, and it can also generate torque, which is essential for regenerative braking or other applications requiring precise motor control.
- Quadrant 1: Forward motoring (positive speed, positive torque).
- Quadrant 2: Forward braking (positive speed, negative torque).
- Quadrant 3: Reverse motoring (negative speed, negative torque).
- Quadrant 4: Reverse braking (negative speed, positive torque).
