DEFINITION

Classification: 318/466

(under subclass 445) Subject matter in which the sensing means are responsive to a predetermined (1) movement (e.g., mere condition of motion, number of revolutions, etc.), (2) limit-of-travel, or (3) other position (e.g., mere presence of, altitude or elevation, etc.) of the motor being controlled or of any body or device.

SEE OR SEARCH THIS CLASS, SUBCLASS:

18, for follow-up motor systems in which the motor is started and/or stopped in response to the position of the "Transmitter".

120, for motor systems having means for stopping a reciprocating or oscillating motor in response to a predetermined number of revolutions or cycles.

128, for motor systems having means for controlling a reciprocating or oscillating electric motor in response to movement or position of the motor or device actuated thereby.

286, and the subclasses specified in the Notes to the definition of that subclass for automatic control of motor reversing in response to movement or position of motor or device actuated thereby. 369, for motor systems having automatic control of the braking of a motor in response to movement or position of the motor or device driven thereby.

396, for motor systems having automatic control of the acceleration of a motor in response to the movement or position of the motor or device driven thereby.

461, and the subclasses specified in the Notes thereto, for motor systems having means responsive to rate-of-change of position (i.e., velocity, speed) of the motor or other devices.
