Abstract: A motor of the invention includes a stator having a slot wound with a coil and a circular shaped housing accommodating the stator, and a rotor disposed on an inner surface of the housing and spaced apart from the slot and having a plurality of permanent magnets having the same number as magnetic poles and having different magnetic polarities. Each of the plurality of permanent magnets has a length corresponding to a first angle according to the number of magnetic poles. The plurality of permanent magnets are spaced apart from each other at a third angle according to the first angle and a second angle corresponding to the number of magnetic poles. The first, second, third angles of the motor refer to a center point of the housing as an angle reference point. The motor of an embodiment may be a motor provided in a washing machine.

Abstract: A driving device including a stator; a rotor including a rotor frame and provided to be rotatable about a rotational axis of a clothing treatment device through interaction with the stator; and a clutch including a movable member configured to slide along the rotational axis to be selectively coupled to the rotor according to an operation mode of the clothing treatment device. The rotor frame may include a plurality of holes, and a plurality of coupling protrusions protruding toward the clutch so as to be coupled with the movable member when the movable member is slid to be coupled to the rotor. The plurality of coupling protrusions are integrally formed with the rotor frame and punched out of the rotor frame to form the plurality of holes.
