Title:
ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2022/074821
Kind Code:
A1
Abstract:
This electric motor (101) has a movable element (30A) and a stator (20). The movable element (30A) has a main teeth pair (1), which is a pair of wound main teeth (11, 12) disposed at positions that are adjacent in the X-axis direction. The main tooth (11) is provided with a tooth (112) in contact with a core back, and a tip core (113) that is located at a position facing the stator (30A) and that is in contact with the tip of the tooth (112). The main tooth (12) is provided with a tooth (122) in contact with the core back, and a tip core (123) that is located at a position facing the stator (30A) and that is in contact with the tip of the tooth (122). The electrical angle between the X-axis-direction center position of the surface of the tooth (112) in contact with the core back and the X-axis-direction center position of the surface of the tooth (122) in contact with the core back is greater than the electrical angle between the X-axis-direction center position of the tip core (113) and the X-axis-direction center position of the tip core (123).
