DEFINITION

Classification: 318/83

(under subclass 82) Subject matter in which means are provided for connecting the armature conductors or windings of one or more motors in series relationship with the armature conductors or windings of one or more other motors at one time and in parallel relationship therewith at another time; or for connecting the armature conductors or windings of one or more motors in series with the armature conductors or windings of one or more other motors and simultaneously connecting the armature conductors or windings of one or more

third motors in parallel with the armature conductors or windings of one or more other motors.

SEE OR SEARCH THIS CLASS, SUBCLASS:

93, for plural motor systems having series parallel connection of the armature circuits of plural motors during the acceleration thereof.

111, and the subclasses listed in the search notes thereto, for other plural motor systems having series parallel connections of the armature windings.

497, and the subclasses specified in the search notes thereto, for single motor systems having parallel connections of two or more armature or primary windings.
