摘要： A stator tooth design for a stator core of a permanent magnet motor. The tooth surface comprises a plurality of surface segments, wherein each surface segment of the plurality of surface segments joins an adjacent surface segment of the plurality of surface segments at an obtuse angle, preferably between 160 and 170 degrees. Alternatively, the tooth surface comprises a single essentially straight surface segment. Each of the plurality of surface segments has a starting edge and an ending edge. Preferably, the starting edge of a surface segment lies along a first circumferential path a predetermined radial distance from the outside edge of the stator core and the ending edge of the surface segment lies along a second circumferential path either closer to or further from the outside edge. The first circumferential path and the second circumferential path can be concentric to the outside edge of the stator core.

摘要： A torque motor and engine throttle valve assembly employing same having an annular stator with a pair of semi-cylindrical shell permanent magnets disposed on the inner periphery of the stator. A pair of rotor pole segments each having an L-shaped configuration in section in the plane of symmetry have an arcuately shaped outer flange. The rotor pole segments are joined axially and oppositely disposed on the motor shaft to form an S-shape in section in the plane of symmetry. A stator coil is assembled with the pole segments on the rotor shaft, and the stator coil is attached to the stator through an open side of the S-shape. The arcuate flanges maximize the rotor material adjacent the radial flux gap between the magnets and the rotor pole segments. In the throttle valve, the rotor pole segments are mounted onto an extension of the throttle blade shaft and the stator is attached to the throttle body.

摘要： A dynamoelectric generator comprises a rotor having a plurality of permanent magnet elements disposed in an annular ring configuration about an axis of rotation, the magnet elements successively alternating in magnetic polarity along an inner annular surface, and a stator spaced from the rotor by a radial air gap. The stator includes a plurality of magnetic core segments having respective coils wound thereon to form stator windings, the core segments separated from direct contact with each other and disposed along the radial air gap. Each stator segment comprises a plurality of poles aligned with each other in a direction parallel to the axis of rotation. Thus the stator comprises a plurality of sets of stator poles in radial alignment, the sets being axially displaced from each other.
