摘要： The present invention provides for a food waste disposer having a food conveying section (102), a grinding section (104), a motor section (106) and a controller (220). The motor section comprises a switched reluctance motor having a rotor and a stator. The controller is electrically connected to the stator to control the switched reluctance machine. The controller is capable of directing rotational movement to the rotatable shaft (126) and the portion of the grinding mechanism mounted thereon. The controller is further capable of maintaining the rotational movement of the rotatable shaft at more than one rotational speed. The present invention also includes methods of operating a variable speed motor in different operational modes such as a soft start mode, optimized grinding mode, idle more, rinse mode, and an anti-jamming mode.

摘要： An electric power steering system for a vehicle includes a steering wheel (16) and a steering shaft (20) that is connected to the steering wheel. A worm gear (26) is connected to the steering shaft (20). A worm (28) is threadably engaged to the worm gear (26). A permanent magnet motor (32) is connected to the worm (28). The permanent magnet motor (32) includes a stator (114) with twelve slots (132) and a rotor (116) with ten poles (126). The rotor (116) includes one or more axial rotor sections.

摘要： A fan assembly includes a fan housing and a fan. A switched reluctance fan motor is mounted in an inlet of the fan housing and includes a shaft that is connected to the fan. The switched reluctance fan motor includes a stator with a plurality of circumferentially-spaced stator segment assemblies that include a stator segment core. Winding wire is wound around the stator segment core. A rotor tends to rotate relative to the stator to a rotational position that maximizes the inductance of an energized winding. A drive circuit energizes the winding wire around the stator segment assemblies based on the rotational position of the rotor. End cap assemblies are connected to opposite axial ends of the stator segment core. The end cap assemblies define an annular channel for receiving the winding wire and for preventing winding creep.
