.~ Plural, diverse or diversely controlled driving motors (e.g., driving differential gearing)
DEFINITION
Classification: 318/8
(under subclass 3) Subject matter in which two or more electric motors are employed to drive a particular load device and in which one or more of the motors (1) are substantially different, structurally, or (2) are controlled or operated differently with respect to time, load, speed, etc., from one or more other of the motors.
(1) Note. This subclass includes subject matter within the class definition where plural diverse or diversely controlled electric motors drive differential gearing.
SEE OR SEARCH THIS CLASS, SUBCLASS:
1, for subject matter within the class definition having an electric motor driving means and a nonmotor driving means.
5, for plural electric motors driving plural diverse, or diversely controlled particular load devices.
7, for this subject matter where the plural motors control the tension or tautness of a material being driven, conveyed or moved by the motor.
34, and the subclasses specified in the Notes to the definitions of those subclasses for other plural electric motor systems within the class definition. 39, for electric motor systems of the work and feed or
indexing type of motor combination where there are a plurality of motors.
