DEFINITION

Classification: 318/53

(under subclass 34) Subject matter in which means are provided for effecting two or more diverse operations of two or more motors.

(1) Note. Combinations of the following single operations are included in this subclass: (a) Reversing control, (b)

Acceleration control; (c) Running-speed control; (d) Braking control; (e) Motor Load control; (f) Automatic stopping and/or starting. The following are not considered to be a single operation such as when combined with only one of the operations in (a) to (f) or with each other form plural diverse motor-operation control for classification in these subclasses: (1) Phase or Power Factor control; (2) Temperature control of the motor; (3) Signalling, Testing, Indicating or measuring conditions in the motor or its system; (4) Ordinary (manual) stopping and/or starting; (5) Phase splitting or phase conversion to supply the motor; (6) Lubricating the motor. For example, operation (a) with any one or more of operations (1) to (6) are not classified in these subclasses.

51, for this subject matter where the system includes plural motors in which one or more of the motors is controlled differently than one or more of the others.

67, for plural motor systems where the system includes means for running one of the motors at a different speed from the speed of another motor.

255+, for motor systems having plural, diverse motor operations control the single electric motors.
