Motor and washing machine having the same

A motor includes a stator having stator cores, a coil wound around the stator cores, and a rotor disposed at an inner side of the plurality of stator cores. The rotor includes a sleeve, a plurality of rotor cores arranged in a circumferential direction of the rotor, a plurality of bridges arranged to connect the sleeve to each of the plurality of rotor cores, a plurality of permanent magnets provided between the rotor cores to form an interior space with respect to the sleeve while being spaced apart from the sleeve, and a plurality of support protrusions protruding from the sleeve in an outward radial direction of the sleeve to support the plurality of permanent magnets while corresponding to the plurality of permanent magnets, respectively, the plurality of support protrusions being arranged between the bridges while being spaced apart from the bridges in the circumferential direction of the rotor.
