摘要：
An electric motor has a pair of brushes for transferring power to windings of a wound rotor by making sliding contact with a cylindrical commutator. Each brush has a body with a pair of end surfaces, and a contact surface extending between the end surfaces and configured to slidingly contact a cylindrical circumferential surface of the commutator. The extending direction of the contact surface is inclined relative to the axial direction of the commutator, and the contact surface is V-shaped when viewed in the extending direction thereof.
