摘要： An induction motor is disclosed which utilizes a liquid in intimate contact with the rotor and stator conductors for cooling and yet minimizes the disadvantages of high rotational drag losses associated with conventional spray cooled motors. Cooling liquid is conducted through a hollow rotor shaft and directed to a cavity at the center of the magnetic length of the rotor. The cavity is formed by separating two adjacent rotor laminations. The cooling liquid flows axially from the central cavity toward the rotor ends through slots which contain the rotor conductors. A sealing band is provided around the rotor laminations to prevent cooling liquid from entering the air gap between the rotor and the stator.

摘要： 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.

摘要： A generating system including a permanent magnet generator having a stator, a rotor journalled for rotation in proximity to the stator and normally separated therefrom by a small air gap. Permanent magnets and windings are provided on the stator and the rotor respectively, or the reverse as desired and a detector is provided for sensing the development of an electrical fault in the winding and for moving the stator away from the rotor to increase the air gap thereby reducing the magneto motive force available to induce current in the winding to prevent burn out of the winding.

摘要： 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.

摘要： The effects of operational loading on a permanent magnet generator of the type having first and second permanent magnet assemblies 28, 30 mounted on a shaft 26, and movable relative to each other is eliminated by rotatably mounting each of the assemblies 28, 30 for rotation relative to the shaft 26, as well as to each other, and connecting them to the shaft by equal, but oppositely pitched helical spline connections 50, 52, 58, 60. Axial movement of the shaft 26 will then cause equal, but opposite relative movement of the permanent magnet assemblies 28, 30, so that the forces resisting movement of one such assembly act to encourage movement of the other, thereby balancing out said forces.

摘要： 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.
