Title:
MOTOR ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2022/173134
Kind Code:
A1
Abstract:
The present invention relates to a motor assembly comprising: a stator comprising a stator core having a plurality of teeth, a stator coil having a plurality of phase coils wound on the plurality of teeth, respectively, and an insulator interposed between the stator core and the stator coil for insulation of the stator coil; and a rotor which has a rotation shaft and is spaced apart from the stator with a space therebetween and is rotatably disposed, wherein each power line of the plurality of phase coils extends to one end of the stator core along the axial direction and each neutral line of the plurality of phase coils extends to the other end of the stator core, and the stator includes a connection ring which is formed of an electrical conductor and is disposed at the other end of the stator core to simultaneously connect the neutral lines of the plurality of phase coils. As a result, the power line and the neutral line of the stator coil are separately disposed at both ends of the stator core, and accordingly, the insulation distance between the power line and the neutral wire can be easily secured.
