Abstract: Method for voltage stabilization during an engine starting event of a vehicle includes receiving, at a switch device module, an active Start_ON signal from a starter solenoid module indicating initiation of the engine starting event. At the switch device module, an auxiliary electrical energy storage device (ESD) is electrically coupled to one or more auxiliary loads within a predetermined delay since the active Start_ON signal was received. A primary ESD and a starter motor are electrically decoupled from the one or more auxiliary loads only after the auxiliary ESD has been electrically coupled to the one or more auxiliary loads. In response to a predetermined condition occurring while the primary ESD and the starter motor are electrically decoupled from the one or more auxiliary loads, the primary ESD and the starter motor are electrically coupled to the one or more auxiliary loads.

Abstract: A rotor for a permanent magnet synchronous machine that includes a rotor core structure. A first set of permanent magnets forms poles within the rotor core structure. Each pole includes a pair of permanent magnets from the first set of permanent magnets. A first set of apertures is formed in a first radial layer of the rotor core structure. Each pole includes a pair of apertures from the first set of apertures. The first set of permanent magnets is inserted within the first set of apertures. Each pair of permanent magnets within a pole cooperatively generates a magnetic field in a same direction within the pole. The magnetic field generated by a respective pair of magnets in a respective pole is opposite to a magnetic field generated by a pair of permanent magnets in an adjacent pole.

Abstract: A rotor of a permanent magnet synchronous machine includes a rotor core structure. A first set of apertures are formed in a first radial layer of the rotor core structure having a first set of permanent magnets disposed therein forming respective poles. A second set of apertures formed in a second radial layer of the rotor core structure of each pole. A third set of apertures is formed in a third radial layer of the rotor core structure. A second set of permanent magnets is inserted within the third set of apertures. A plurality of bridges each extends across a respective side of each of the third set of apertures in the third radial layer. The plurality of bridges provides structural support of the rotor core structure when operating. The plurality of bridges are integrally formed as single-piece laminations.

Abstract: An electrical system includes a battery for providing electrical power to a starter mechanism and an auxiliary load of a hybrid-electric vehicle. An electric double-layer capacitor (“EDLC”) is electrically connectable to the battery and the auxiliary load. A separation switch is electrically connected between the battery and the EDLC for electrically separating the battery from the EDLC and the auxiliary load. The separation switch is opened in response to the voltage across the battery being less than the voltage across the EDLC.
