<p>The molded commutator has commutator segments (1); cylindrical varistor pins (20) press-fitted between the adjacent commutator segments; and molding material (3) for molding commutator (1) and varistor pins (20) as an integral structure to form a molded commutator. Varistor pins (20) suppress spark voltage between the commutator segments, extending the operating life of the brush.</p> |
