DEFINITION

Classification: 318/822

Responsive to motor condition:

(under subclass 821) Subject matter wherein the impedance element of the circuit is controlled by a motor characteristic.

(1) Note. The motor characteristics include secondary motor voltage, the secondary motor current, the primary motor current, and the motor rotor speed.

(2) Note. The term "controlled" includes the addition, removal, the shorting out, or somehow changing the value of the impedance element or elements of the circuit.
