Collector ring for motor, and motor

A motor, the motor comprising a stator wire outlet end, and a collector ring, wherein the collector ring has a connecting end, the connecting end including a base part and a welding part which is vertical relative to the base part, the base part is provided with a positioning hole and an elastic part, the positioning hole is a through hole, the positioning hole is used to permit a stator wire outlet end of the motor to pass through,

• and the elastic part is formed so as to be capable of applying an elastic force to the stator wire outlet end along a first direction serving as a length direction of the base part, so that two opposite side surfaces of the stator wire outlet end along the first direction are in close contact with the base part and the welding part, respectively the stator wire outlet end being connected to the welding part of the collector ring by welding.
