Abstract
A commutator includes a substantially tubular insulating core, a first slip ring fixed to the core, a plurality of first bars electrically connected to the first slip ring, a second slip ring fixed to the core, and a plurality of second bars electrically connected to the second slip ring. The first bars and the second bars are fixed to the outer surface of the core and are alternately arranged at equally spaced intervals in the circumferential direction of the core. The first slip ring and the second slip ring are arranged on the same side of the first bars and the second bars. The first and second slip rings respectively comprise a contact surface that is substantially perpendicular to the axis of the commutator and is configured for contacting brushes.
