ABSTRACT:
An electric motor or generator has a rotor and a stator comprising a generally cylindrical yoke having poles secured to the interior thereof. The yoke is closed by end members secured thereto, said end members mounting bearings for the rotor. The yoke consists of a continuous spirally wound coil of metal strip. The convolutions of said coil are secured so that the coil forms a monolithic structural element which mechanically interconnects the end members, without the need for additional frames or ties.
