Abstract: A stator of a brushless motor is disclosed which includes a stator core, an insulating frame arranged on the stator core, and a plurality of windings wound around the insulating frame. The stator core includes a ring-shaped yoke part and a pole part mounted to the radial inner side of the yoke part. The pole part includes a plurality of teeth spaced-apart from each other along the circumferential direction, and a ring-shaped portion arranged at and connected to the radial inner side of the teeth. The radial outer sides of the teeth abut against the radial inner side of the yoke part. The insulating frame is arranged on the pole part. A plurality of power terminals are fixed to one axial end of the insulating frame and respectively electrically connected to the windings.

Abstract: An electric motor has an end cap assembly having a ground connection. The motor has a housing, a brush assembly including brushes, electrical components and a terminal holder, an end cap, and a ground plate. The brush assembly is secured in an open end of the housing. The end cap is positioned on an outer side of the brush assembly and fixed to the housing. The ground plate is disposed between and is resiliently compressed by the brush assembly and the end cap. The plate includes a plurality of elastic structures. Each elastic structure resiliently bears against corresponding leads of at least some of the electrical components. The ground plate is electrically connected to at least one of the housing and the end cap to accomplish a ground connection.

Abstract: An electric motor has a stator, a rotor, two motor terminals and a filter circuit for suppressing electromagnetic interference. The filter circuit includes a flexible circuit assembly having a FPCB. Multiple filter elements are mounted to the FPCB. There are less connection points between the filter circuit and the motor terminals, which leads to higher reliability of the motor.
