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.
