Abstract
A motor stator includes a stator core, first and second insulating members and a stator winding. The stator core defines upper and lower ends and has a central through hole and a plurality of stator slots distributed along a circumferential direction of the stator core, and each stator slot includes first and second slot segments. The first insulating member is disposed in the stator slot. The second insulating member is disposed at at least one of the upper and lower ends of the stator core, and defines a central hole and a plurality of grooves corresponding to the plurality of stator slots respectively. A flange is formed on the second insulating member along a peripheral of the groove and fitted within the second slot segment. The stator winding is wound on the stator core and passing through the plurality of stator slots and grooves.
