Abstract
An electric motor and an electrical appliance are provided. The electric motor includes a rotating shaft, a stator, a rotor disposed on the rotating shaft, spaced apart from the stator, and embedded in the stator, a first end cover, and a first bearing. The first bearing includes a first outer ring fixed on the first end cover and insulated from at least part of the first end cover, a first inner ring embedded in the first outer ring, and a first ball disposed between the first outer ring and the first inner ring. The rotating shaft is fixed on the first inner ring and rotationally supported on the first end cover. The part of the first end cover that is insulated from the first outer ring is short-circuited with a stator core of the stator and is grounded.
