Any circuit for driving a motor that's more complex than wiring it to a power source through a simple on/off switch. Examples include speed and torque control using H-bridges, brushless motor controllers, stepper controllers, VFDs. Constant speed examples include relay control, reversing, reduced-voltage starting, overload protection and other control requirements more complex than a simple 0n/off switch.

Pole counts for VFD driven induction motor
What is the significance of pole count of IM if it is driven by a VFD? If we are using the power supply frequency (50Hz or 60Hz), the pole counts matter in terms of torque and synchronous speed.
But i …

Effect of bandwidth of stator winding in induction motor
The stator in squirrel cage induction motors is an RL circuit with 3db attenuation
$$
\frac{R}{2\pi L}Hz
$$
Does that mean an IM designed for 60Hz should also have the stator bandwidth at least 60Hz? …
