Abstract: A rotor for a permanent magnet generator has a carrier of nonmagnetic material. One or more elements of magnetic material are carried by the carrier and provide a magnetic path in parallel with the primary magnetic path for operating flux which is coupled with the stator windings. The number of magnetic elements used determines the amount of flux diverted from the stator and thus adjusts the voltage generated in the stator winding.

Abstract: Combined Starting/Generating System and Method A power conversion system for converting between electric and motive power may be utilized either in a generating mode to generate electric power from motive power supplied by a prime mover or in a starting mode wherein motive power is developed by the power conversion system from electrical power and is supplied through a torque converter to the prime mover to start same. The power conversion system includes a main generator, an exciter and a permanent magnet generator, or PMG, which together comprise a brushless alternator. When operated in the starting mode, power is supplied to the PMG to cause it to act as a motor and thereby drive a rotor which is common to the PMG, exciter and main generator. Once a predetermined operating condition of the generator is attained, the main generator is supplied power from a motor control to cause the generator to act as a synchronous motor and the power supply to the PMG is disconnected. The torque converter is then commanded to transfer motive power from the generator to the prime mover to start same.

Abstract: A rotary electric machine such as a brushless generator including a housing, a stator within the housing and a rotor journalled within the housing. A stationary element is affixed to the housing and extends axially into a cavity in the rotor and a barrier is provided in the air gap between the stator and the rotor. The barrier serves to isolate the flow of coolant to the stator from the air gap and the stationary element serves as a means for mounting, within the rotor, components of a permanent magnet generator and an exciter which may be wholly contained within the rotor. The stationary element is also provided with a conduit for conducting coolant to the various components of the rotor.

Abstract: The cooling efficiency in a rotary electric machine is improved by providing direct contact between the coolant and the sources of heat while preventing high drag loss from coolant entering the air gap between the moving and stationary parts of the rotary machine. The rotary electric machine such as a brushless generator includes a housing (10), a stator (24) within the housing (10) and a rotor (22) journalled within the housing (10). A stationary element (60) is affixed to the housing (10) and extends axially into a cavity (58) in the rotor (22) and a barrier (48) is provided in the air gap (34) between the stator (24) and the rotor (22). The barrier (48) serves to isolate the flow of coolant to the stator (24) from the air gap (34) and the stationary element (60) serves as an arrangement for mounting, within the rotor (22), components of a permanent magnet generator (90) and an exciter (92) which is wholly contained within the rotor (22). The stationary element (60) is also provided with a conduit (64) for conducting coolant to the various components of the rotor (22).
