Abstract
A motor apparatus includes a multi-lane permanent magnet synchronous motor having at least two sets of phase windings, and a control circuit. The control circuit selectively connects a first direct current power source to the motor phase windings of a first set of the motor phasing windings to form a first lane. The control circuit may also selectively connect a second direct current power source to the motor phase windings of a second set of the motor phasing windings to form a second lane. The control circuit may cause current to flow in the motor that meets a current demand from a current demand circuit. During at least one mode of operation, the control circuit may apply waveforms to a motor phase winding which causes an actively controlled transfer of energy from the first direct current source of the first lane into a component of the second lane.
