DEFINITION

Classification: 388/848

OPEN LOOP ACCELERATION CONTROL SYSTEM FOR DC MOTOR WITH COMMUTATOR:

(under the class definition) Subject matter wherein a derived reference signal is applied to the input circuit of a commutating DC electric motor to regulate acceleration or deceleration of the motor.

(1) Note. In this subclass, and the subclasses indented hereunder, the control circuitry may function in either a digital mode or an analog mode or a combination of digital and analog modes. See the Glossary in the class definition for "digital" and "analog."
