A method of manufacturing the rotor of a coreless motor comprises the steps of molding a coil positioning disc integrally with the commutator of the motor, disposing rotor coils on or in the disc, and securing the coils thereto, thereby assembling the coils into the rotor at positions which achieve a dynamic and a magnetic balance of the rotor. In this manner, a balanced rotor is provided.
