DEFINITION

Classification: 318/108

(under subclass 107) Subject matter in which one or more of the sources of supply, supply electric energy at one voltage magnitude and one or more others of the sources supply energy at another magnitude of voltage.

(1) Note. Two voltages are of different magnitudes if, at any time during normal operation, one of them has a magnitude substantially different in effective value than the other. Hence, if the magnitude of one of the sources is varied relative to the magnitude of the other so as not to be the same, the two sources are considered to be of different voltages.

SEE OR SEARCH THIS CLASS, SUBCLASS:

109, for plural motor systems having similar types of sources (e.g., all ac sources or all DC. sources) for the motors in which one or more of the sources differ in voltage magnitude from one or more others of the sources.

442, for motor systems having plural sources of supply for a single motor in which the voltages of the sources differ in magnitude from one another.
