Document Type and Number:
WIPO Patent Application WO/2017/092191
Kind Code:
A1
Abstract:
Disclosed are a stator punching, a stator assembly and an external rotor motor. The stator punching comprises a punching body (1) with a central hole, the punching body (1) comprises an annular yoke (10) and a plurality of first teeth (11) and second teeth (12) extending outward from the outer edge of the annular yoke (10), the first teeth (11) and the second teeth (12) are arranged alternately in a circumferential direction, each of the first teeth (11) comprises a common tooth root (111) and at least four projected teeth (112) extending outward from the common tooth root (111), a first embedding wire slot (13) is formed between each two adjacent projected teeth (112), a second embedding wire slot (14) is formed between adjacent first tooth (11) and second tooth (12), and the depth of the first embedding wire slot (13) in the radial direction of the punching body (1) is less than the depth of the second embedding wire slot (14) in the radial direction of the punching body (1). The stator punching can improve the performance of the motor.
