How does torque control work?

Direct torque control (DTC) is one method used in variable-frequency drives to control the torque (and thus finally the speed) of three-phase AC electric motors. This involves calculating an estimate of the motor’s magnetic flux and torque based on the measured voltage and current of the motor.

How does VFD control torque?

VFD generally operates in the constant torque mode by supplying constant volt/Hz to stator of the induction motor. The PWM inverter of the VFD increases the voltage and frequency in the same ratio, and thus the torque delivered by the motor remains constant.
