<p>A unitary starter motor and generator including a rotor assembly having as plurality of circumferentially disposed rare earth-iron permanent magnets, a stator assembly within which said rotor assembly is rotatable, said stator assembly including a laminated annular stator body formed from a silicon containing iron alloy of high electrical resistivity and low magnetic loss, and a multiphase stator winding secured to the inner periphery of said stator body and lying in the airgap defined between the stator body and the rotor assembly. A semiconductor inverter-rectifier assembly electrically connected with said multiphase stator winding for rectifying and controlling the output from the stator winding when acting in generator mode, and for switching the input to the winding when operating in motor mode, and, a sensing means associated with said semiconductor inverter-rectifier assembly whereby the angular position of the rotor assembly is determined for controlling switching of the electrical input to the stator winding to afford operation in motor mode.</p> |
