Abstract
PURPOSE: To eliminate the step of forming an undercut at a mica piece interposed between commutator plates after forming brush contact surface of the commutator by forming the undercut in advance at the mica piece and assembling the piece alternatively among the commutator plates for cutting step.
CONSTITUTION: A brush contact surface 10a is formed on a commutator plate 10 by alternatively laminating mica pieces 20 each having an undercut 20a at the position in height h1 among commutator plates 10 of sector shape in sectional area to thereby assemble a cylinder, fixing it to a core metal 3, and then cutting it at the position in height h2. Thus, the undercut 20a is formed at the position lower by t=h2-h1 from the brush contact surface 10a to thereby eliminate the step of forming the undercut 20a at the mica piece.
