Patent ID: 8659215

Claim:
A motor comprising: a cylindrical stator core; a first framework fixed to the first side of the stator core in an axial direction; a first bearing housing fixed to the outside of the first framework, wherein the first bearing housing holds a bearing; a second framework fixed to the second side of the stator core in the axial direction; a second bearing housing fixed to the outside of the second framework, wherein the second bearing housing holds a bearing; a rotor comprising: a rotational shaft rotatably supported by the bearings, wherein the rotational shaft extends into the first and second frameworks; a rotor core attached to the rotational shaft, wherein the rotor core faces an inner side of the stator core; and a first support base and a second support base fixed to the rotor, wherein the first support base and the second support base are interposed by the rotor core; a first locking member movably coupled to the first framework, wherein the first locking member is configured to move along the axial direction of the rotational shaft toward a side of the rotor core to contact the first support base and fix the rotor; and a second locking member movably coupled to the second framework, wherein the second locking member is configured to move along the axial direction of the rotational shaft toward a side of the rotor core to contact the second support base and fix the rotor.
