摘要： A method for controlling voltages in an integrated starter alternator electric machine is provided where the armature windings are manipulated in a Δ/Y/Δ fashion. In particular, the armature windings are arranged in a Δ connection during engine cranking operation, when the electric machine acts as a starter motor. After the engine is cranked, the windings are changed into a Y connection when the ISAD machine changes from motoring to generating and operates a low speeds, such as idle speed. Next, when the engine speed increases above a predetermined winding reconfiguration speed, the windings are switched from Y to Δ connection. If the engine speed falls below the winding reconfiguration speed, the machine again switches the armature windings to a Y connection to take advantage of the efficiencies of the Y connection at that low speed range in the generating state.
