Abstract: Exemplary embodiments disclose a rotor of an electric motor and an electric motor using the same. The rotor includes a core which includes a plurality of protrusion portions which are arranged along an outer circumference of the core and protrude radially to an outer portion of the core, and a plurality of concave portions interposed between the protrusion portions; a plurality of permanent magnets which are respectively disposed at the plurality of concave portions; and a plurality of pole pieces which are disposed at the plurality of concave portions and at outer sides of the plurality of permanent magnets. A length of each of the plurality of pole pieces in an axial direction is shorter than a length of each of the plurality of protrusion portions in the axial direction.

Abstract: A motor for a washing machine includes a stator and a rotor. The rotor includes a rotor casing including a base portion formed in a disk shape and a vertical wall extending substantially perpendicularly from an outer periphery of the base portion, a permanent magnet provided on an inner surface of the vertical wall of the rotor casing, and a connecting member provided at a center of the base portion of the rotor casing and connected to a shaft. The base portion of the rotor casing includes a first ring portion facing a coil portion of the stator and a second ring portion, provided with a plurality of air inlet holes, that is positioned between the first ring portion and the connecting member and does not face the coil portion of the stator.

Abstract: An in-wheel assembly includes an in-wheel actuator and a wheel. The in-wheel actuator includes a driving motor, a decelerator which is disposed in the driving motor and configured to decrease a rotational speed received from the driving motor, and an output shaft which is configured to receive the rotational speed decreased by the decelerator. The wheel is configured to accommodate the in-wheel actuator in an inner space and is driven by the rotational speed of the output shaft to rotate.
