.~.~ By space-discharge or unidirectionally conductive devices in energizing circuit
DEFINITION
Classification: 318/132
(under subclass 126) Subject matter in which the means for controlling the energizing circuit of the motor includes a space-discharge device or an unidirectionally-conductive device connected in series with or in shunt to the energizing winding of the motor.
SEE OR SEARCH THIS CLASS, SUBCLASS:
125, for this subject matter where the motor has plural windings.
505, and the subclasses specified in the search notes thereto, for other motor control systems having space-discharge devices in the armature or primary circuit of the motor.
