Abstract
A vehicle includes a five-phase electric machine with open windings driven at each side by phase legs of an inverter. A controller monitors for open-circuit windings. In response to detecting an open-circuit winding above a predetermined speed threshold, the controller operates the inverter to drive the windings that are not open-circuited in a square configuration.
