MOLDING APPARATUS FOR A ROTOR OF AN ELECTRIC MOTOR

摘要

A molding apparatus for a rotor of an electric motor comprises a casting form made as a laminated rotor core, which is covered by a hood on perimeter and from faces by two half-forms, a riser with a can attached via a feeding gate to one of half-forms. At least one half-form has air gates united with a commutator. Between the core and the hood there is a hollow connected via channels to the commutator which has a hole in its wall for vacuum pump attachment.
