ABSTRACT:
An improved small electric motor for use as a power source for toys, small electric instruments, and portable electric instruments, and a method for manufacturing rotors for such motor. The small electric motor is provided on a rotary shaft with a commutator provided in parallel and feeder brushes in resilient contact with the commutator. The commutator is fitted to the rotary shaft in a manner providing simplicity of assembly, adjustable positioning of the commutator on the rotary shaft, standardization of a magnet case, and favorable performance in the small motor.
