DEFINITION

Classification: 318/123

(under subclass 122) Subject matter in which there is either a polyphase alternating current supply, or two or more sources of supply, one or more of which are different or differently controlled than one or more others of the sources, connected to supply energy to the two or more of the motor windings.

(1) Note. All the phases or sources of supply may be connected to each of the several windings, or one or more of the sources or phases may be connected to one or more of the windings and one or more others of the sources or phases may be connected to one or more others of the windings. The several sources or phases may be connected simultaneously or at different times.
