Abstract of the Disclosure A coreless motor in which a coil of rotor wound into a hollow cylindrical shape is rotatably disposed concentrically in an air gap between a central cylindrical permanent magnet and a cup-shaped yoke surrounding the magnet. In the cylindrical coil of rotor, insulative coating of the coil at respective bent parts of the coil at an end edge of the rotor's cylindrical shape is taken off over the entire periphery of said end to expose inner conductive wires at the bent parts so that an electric current will be fed to the coil through brushes which are brought into contact with such exposed conductive wires of the coil.
