A mechanically commutated motor (200) configured for use with an external magnetic field (240) is disclosed. The motor (200) includes an axle (208) formed of anon-magnetic material. A rotor (206) is coupled to the axle (208), the rotor (206) including three or more actuator units (205) spaced about the axle (208). Each actuator unit (205) comprises a non-magnetic material, a coil winding (214) along each of the three or more actuator units (205), and a commutator (216) coupled to the axle (208) and electrically associated with the coil windings (214). The motor (200) further includes two or more resilient contacts (210) oriented to direct a current through the commutator (216) to one of the coil windings (214) to induce a current in the coil winding (214) to form an electromagnet that rotates the rotor (206) relative to the external magnetic field (240) from a magnet located external to the mechanically commutated motor (200).

A motor includes a bottomed cylindrical housing incorporating a rotor that rotate integrally with a shaft and a stator, and an end bell having an end plate that closes an opening of the housing and a holder that is provided between the rotor and the end plate in an axial direction and to which an electrical element is attached. The end plate has an air hole penetrating the end plate in the axial direction. The holder includes an attachment portion to which the electrical element is attached, and has an insertion hole through which the shaft is inserted. At least part, of the attachment portion, overlapping the air hole when viewed in the axial direction has a cutout portion.
