A washing machine includes a motor. The washing machine includes a cabinet, a tub arranged inside the cabinet, a drum rotatively arranged inside the tub, and the motor. The motor includes a stator arranged on the rear wall of the tub, and a rotor. The stator is arranged to rotate by electromagnetically interacting with the stator. The rotor includes a plurality of rotor cores alternatingly arranged with a plurality of magnets in a radial form. Each of the rotor cores includes a body, a tooth formed in the front end part of the body, a first groove formed in the upper part of the body, and a second groove formed in the lower part of the body. A partition between the first and second grooves constitutes a part of the body providing an interval between the first and second grooves.

Motor and washing machine having the same

A rotor and a motor including the same. The motor includes a stator and a rotor configured to rotate by interacting with the stator. The rotor includes a plurality of permanent magnets disposed in a circumferential direction of the rotor and rotor cores disposed between the plurality of permanent magnets. The rotor core includes a notch cut inward from a circumferential surface thereof, and the notch is formed in an asymmetric shape. The rotor core has a notch formed on one side of the circumferential surface and the rotor core has a shape inverted left and right with the rotor core are alternately stacked, so that a magnitude of a synthetic cogging torque generated in the rotor is reduced.

Rotor and motor including the same
