VVVF fed to the motor controls its speed and torque. DC bus energy storage isolates the input "front-end" from motor control "back-end." The motor side can have a different kVA rating than mains power. True power conversion, i.e., "kW in = kW out" Motor and inverter can regenerate mechanical power back into the DC bus.
