Abstract
An electric motor includes a stator and a rotor. The stator includes a stator core, a stator winding, a first insulating frame, a number of first insulating elements, and a number of second insulating elements. The stator core includes a number of teeth. Adjacent teeth form a winding passage defining a winding opening. Each first insulating element is assembled within the corresponding winding passage. Two end portions of each second insulating element are placed over the corresponding winding opening.
