Claim Text:
1. A motor usable with a washing machine, the motor comprising: a stator mounted to a tub of the washing machine; and a rotor to rotate a drum of the washing machine, the stator comprising: a stator core; a first insulator and a second insulator arranged to cover the stator core; a plurality of mounts to couple the stator to the tub, the plurality of mounts being selectively provided at only one of the first insulator and the second insulator; and a cover to cover at least a portion of the plurality of mounts and to come into direct contact with the tub when the stator is mounted to the tub, the cover being selectively provided at one of the first insulator and the second insulator at which the plurality of mounts are not provided, wherein each of the plurality of mounts includes a fastening member, a coupling boss having a coupling hole configured to receive the fastening member inserted thereinto, a contact surface to come into direct contact with the tub when the stator is mounted to the tub, and a supporting surface formed at an opposite side of the contact surface to support the fastening member, wherein the coupling boss is comprised of a single member extending from the contact surface to the supporting surface, wherein each mount, including corresponding coupling boss, is spaced apart from other mounts, each of the plurality of mounts further includes a sleeve inserted into the coupling hole to reinforce the coupling boss; the coupling boss includes a stopper to support one end of the sleeve to prevent the sleeve from protruding out of the coupling boss; and the stopper has a stepped portion protruding inward from the coupling boss.
