DEFINITION

Classification: 318/51

(under subclass 34) Subject matter in which means are provided for controlling one or more motors to effect one operational control thereof and for controlling one or more other motors to effect a different operational control thereof.

(1) Note. This subclass is designed to include systems in which the controls for different motors (which may be of the same type) differ from each other; i.e., substantially the same operational control is not exercised over all motors. The same kind or type of control applied to different motors merely at different times is not included herein. For example, see subclass 67 for plural motor systems where means are provided for running one motor at a different speed from another, and subclass 91 for plural motor systems having means to accelerate or decelerate the motors in succession or selectively.

(2) Note. For example, means may be provided for controlling the running speed only of one motor and for controlling the rate of acceleration only of another motor whether at the same or different times.

35, for plural motor systems where one motor has a different type of motion from the motion of another motor (rotary motor and reciprocating motor).

39+, for work and feed or indexing motor combinations involving different controls for different motors.

53, for plural motor systems where the system includes means for effecting two or more diverse operations of the motors (reversing, running speed control, braking, acceleration, deceleration, automatic stopping or starting) the control operations being effected upon all the motors, either simultaneously or in sequence. 67, see Note 1 above.

91, see Note 1 above.
