DEFINITION

Classification: 318/802

Responsive to an additional condition:

(under subclass 801) Subject matter wherein the circuit connected to the primary member of the motor is responsive to another condition as well as being responsive to the speed or the rotational phase angle of the motor.

(1) Note. Subject matter of this subclass type includes feedback sensing of a motor condition or some characteristic of the motor control circuit and may include the sensing of motor current, voltage, or a signal indicative of some characteristic of the control circuit.
