ABSTRACT:
A rotor of a coreless motor high in mechanical strength and durable against a high torque for a long time is provided. A non-metal disk member is provided for holding a cylindrically wound coil secured at its one axial end to the periphery of the disk in coaxial relation to a metallic rotary shaft coupled at one end to the disk member whereby the coupling force between the disk member and the rotary shaft is made high. The disk member and rotary shaft may be made into an integral body with the same metal material. Commutator segments for feeding a source current to the coil are provided on the disk member through an insulative layer.
