SPLIT STATOR OF ELECTRIC MOTOR
First Claim
1. A split stator for an electric motor comprising:
- a yoke portion that is divided in a circumferential direction of a cylindrical stator of the electric motor, a tooth portion that extends from the yoke portion in a radial direction of the cylindrical stator, and a coil wound on the tooth portion, wherein the coil is housed in a coil-housing portion defined by the yoke portion and the tooth portion and is covered with a cover that covers the coil-housing portion, and the cylindrical stator is formed by a plurality of split stators that are divided in a circumferential direction of the cylindrical stator.

Abstract
A stator of an electric motor is formed by a plurality of split stators that are divided in a circumferential direction of the cylindrical stator. Each split stator comprises a yoke portion that is divided in the circumferential direction, a tooth portion that extends from the yoke portion a in a radial direction, and a coil wound on the tooth portion. The coil is pressed into the coil-housing portion, defined by the yoke portion and the tooth portion, by a press die. While the coil is pressed into the coil-housing portion by the press die, the coil may be covered by, for example, being integrated with a resin. Thus, the risk of damaging the coating of the coil is significantly reduced, the coil density is improved, and good circularity of the stator is ensured.
