    Abstract: A method for operating a switched reluctance electrical generator in a manner that is highly efficient involves initially performing a mapping technique to obtain data relating to all of the possible operating conditions of the generator system that generate the desired output power. This mapping technique can be performed empirically or by computer simulation. Then, the effective phase currents supplied to the windings on the stator are measured or calculated. Next, the optimum conduction angles can be selected as those turn-on angles and turn-off angles that occur using the smallest effective phase currents supplied to the windings on the stator. Lastly, the generator system is operated using the selected optimum turn-on and turn-off angles. If desired, a feedback loop can be provided for comparing the actual output power that is generated by the generator system with a desired reference output power level to insure that such actual output power is maintained at or near the desired output power. To accomplish this, the conduction angles can be adjusted in response to such comparison to increase or decrease the actual output power as necessary.

    Abstract: An ordinance platform with a variable reluctance electric motor is provided. The motor has a stator integrated with a bearing race which is fixably connected with the tank body. The bearing race provides the function of a rotor and is fixably or integrally connected with the tank turret. The rotor is vertically supported by the stator for rotational movement by a plurality of ball bearings. The stator is formed having a plurality of individual phase segments which are arranged in an annular array. Each of the stator phase segments is provided with a phase winding and a plurality of stator pole teeth. The stator phase windings are connected individually to respective driver circuits so as to essentially create a plurality of individual stators about the rotor. The rotor race is formed and is provided with a plurality of rotor pole teeth which are disposed adjacent the stator pole teeth. Thus, when the phase windings of the individual stator phase segments are energized, the moveable race (integrated with the rotor and connected with the gun turret) is rotated relative to the stationary race (integrated with a stator and connected with the tank body), without any intermediate coupling device such as gears, belts and the like.

    Abstract: A variable reluctance electric motor includes a stator having a plurality of axially extending inner teeth and a rotor assembly rotatably supported therein. The rotor assembly includes a shaft having a plurality of rotor pole sub-assemblies provided thereon. Each of the rotor pole sub-assemblies includes a hub secured to the shaft, a pair of annular rotor packs secured to the ends of the hub, and an electromagnetic coil disposed loosely about the hub between the two rotor packs. Each of the rotor packs has a plurality of axially extending outer teeth formed thereabout which are disposed adjacent to the inner stator teeth. The rotor pack teeth of each of the rotor pole sub-assemblies are angularly offset from one another, preferably by equal amounts. The electromagnetic coils are engaged by the stator such that the rotor assembly is free to rotate relative thereto. The electromagnetic coils are sequentially energized and de-energized so as to create sequential magnetic circuits between each of the rotor pole sub-assemblies and the stator. These magnetic circuits sequentially cause the angularly offset teeth of the rotor packs to be attracted to the teeth of the stator, resulting in rotation of the rotor assembly relative to the stator.

    Abstract: A synchronous inductor electric motor includes a hollow stator having a plurality of permanent magnets secured to the inner surface thereof. The magnets are radially polarized in alternating fashion about the inner circumference of the stator. A plurality of radially inwardly extending stator teeth are provided on each of the magnets so as to exhibit a polar magnetization which is the same as the adjacent magnets. A rotor assembly supported concentrically within the stator includes a shaft having a plurality of rotor pole sub-assemblies provided thereon. Each of the rotor pole sub-assemblies includes a hub secured to the shaft, a pair of annular rotor packs secured to the ends of the hub, and an electromagnetic coil disposed loosely about the hub between the two rotor packs. Each of the rotor packs has a plurality of axially extending outer teeth formed thereabout which are disposed adjacent to the inner stator teeth. The rotor pack teeth of each of the rotor pole sub-assemblies are angularly offset from one another. The coils are engaged by the stator such that the rotor assembly is free to rotate relative thereto. The coils are sequentially energized and de-energized so as to selectively polarize the associated rotor packs. As they are magnetized, the angularly offset teeth of the rotor packs are attracted toward and repelled from the adjacent teeth of the stator, resulting in rotation of the rotor assembly relative to the stator.
