초록 ▼

Motor for commercial and industrial applications such as golf carts and lift trucks. Features include a thin shell; stator; stator winding; and rotor. Rotor laminations have equally circumferentially spaced semi-closed slots having area for receiving conductors, and the ratio of the number of rotor lamination slots to the rotor outer diameter (measured in inches) is greater than 14.0. In one construction, this ratio is about 15.75; the ratio of the outer diameter to the rotor slot length is from about 9.04 to about 9.16; and the ratio of rotor slot depth or length to rotor slot opening width is from about 10.8 to about 12.5. Cylindrical stator lamination has a given outer diameter and a certain bore diameter determined by the distance between opposing poles. Through-bolt holes are located in the yoke, proximate the outer periphery thereof, and centered with respect to each pole. The ratio of stator pole neck minimum width to two times the yoke thickness or width is from about 0.809 to about 1.009. Methods of assembling motor components are also revealed.
