Q. Methods for speed and torque control of induction motors?

The following are methods available for speed and torque control of induction motors.

• Pole-changing method

• Variable-frequency method

• Variable-line-voltage method

• Variable-rotor-resistance method

• Rotor-slip frequency control

• Rotor-slip energy recovery method

• Control by auxiliary devices (Kramer control, Scherbius control, Schrage motor)

• Solid-state control (variable-terminal-voltage control, variable-frequency control, rotor-resistance control forwound-rotormotors, injecting voltage into rotor circuit ofwound-rotor motors) usually discussed under power-semiconductor controlled drives.
