A worm is threadably engaged to the worm gear. A permanent magnet motor is connected to the worm. The permanent magnet motor includes a stator with twelve slots and a rotor with ten poles. The rotor includes one or more axial rotor sections. If more than one axial rotor section is employed, the axial rotor sections are rotationally offset.

Abstract: A brushless DC motor minimizes a chance of dislocation of or damage to an insulator used in the brushless DC motor. Slant portions are provided at end portions of the insulator; therefore, even if a nozzle of a machine for installing a winding should hit the insulator while moving between teeth, the insulator moves in a direction for coming in close contact with a slot aperture, i.e., in a direction substantially at right angles to a direction in which the nozzle moves. This arrangement prevents the insulator from moving by being pushed by the nozzle, making it possible to minimize a chance of occurrence of an insulation failure caused by a damaged or dislocated insulator.

Abstract: A dynamoelectric machine constructed for speed and accuracy of manufacturing has a stator core constructed of 90° symmetrical stator laminations and the windings have differing numbers of poles which overlap in slots of the stator core are wound of the core formed by the laminations in unique fashion. The rotor bars of the machine are skewed to optimize performance of the machine when in the form of a single phase induction motor. Magnet wire leads of the windings are connected directly to terminals on a plug and terminal assembly which is formed for positive location on an end frame of the machine without welding or other fastening to the end frame. The end frames of the machine and stator laminations forming the stator core are formed so as to increase the precision of the final position of the stator relative to the rotor assembly of the dynamoelectric machine. The end frames are constructed for grounding without the use of fasteners or wire. The engagement of the end frames with the stator core is employed as the basis for alignment of the machine components.
