Abstract

Electromotive machine of the type having a stator (14) and a rotor (15). The stator is provided with multiple sets of windings (quadrants 1:4, Fig. 1), each independently electrically coupled to an electrical means to establish separate power channels between the windings and the electrical means that allow for the simultaneous independent transmission of power through the channels when the machine is in operation. In case of failure in one of the windings (quadrants 1:4), operation of the machine can continue through use of the remaining windings. The machine may take the form of either a motor or generator.
