Abstract:
A motor includes a rotor having a rotation shaft, a stator arranged oppositely in a circumferential direction of the rotor, and a pair of bearing portions rotatably supporting the rotation shaft, the pair of bearing portions each include a first bearing being rotatable together with the rotation shaft and a second bearing being rotatable together with the first bearing, the first bearing rotates together with the rotation shaft when the first bearing is normal, and the second bearing as well as the first bearing rotates together with the rotation shaft when the first bearing is abnormal.
