A system and method are provided whereby at least two motors driven by an inverter coupled to a DC bus are configured to alternate between regenerative and injection braking such that at least one motor is placed in regenerative braking mode and at least one motor is placed in motoring mode. Energy is simultaneously placed on and removed from the DC bus in a manner allowing a large current to flow in as many motors as possible, for fast stoppage of load inertia. At least one motor may be placed in regenerative braking mode and at least one motor in DC injection mode, such that energy is simultaneously placed onto and removed from the DC bus, respectively. Further, a single motor may be is alternated between regenerative braking and DC injection braking, such that energy is alternately placed onto and removed from the DC bus, respectively.
