ABSTRACT:
An ironless rotor of high accuracy is provided readily and simply by coiling an elongated conductor into a plurality of hexagonal windings with a predetermined thickness, wrapping the windings around a cylindrical core member in such a manner that any overlap of the windings does not exceed two layers, and shaping the windings into an integral cylindrical form. Such ironless rotor is applicable to miniature electric motors to enhance the efficiency of the latter.
