Abstract: A motor includes a base, a rotor assembly, a first bearing, an elastic member, and a support member. The base includes a body and a support. The body includes a shaft hole. The support is arranged at an inner surface of the shaft hole. The rotor assembly includes a rotation shaft. The bearing is sleeved at the rotation shaft and at least partially mounted in the shaft hole. The rotation shaft is connected to an inner ring of the bearing and configured to rotate relative to an outer ring of the bearing. The elastic member is arranged between the support and the bearing and configured to apply pressure to the outer ring of the bearing. The support member is arranged at the rotation shaft. The support member abuts against the inner ring of the bearing and is configured to provide a support force to the inner ring of the bearing.
