(under subclass 140) Subject matter in which the motor is an alternating current motor (i.e., a motor which operates when the armature or primary circuit is supplied with alternating current) and in which the generator supplies an alternating current to the armature or primary circuit of the motor.

700+, for other synchronous motor systems. 725+ for other repulsion motor systems. 727+ for other induction motor systems.

310, Electrical Generator or Motor Structure,
159, for structural details of alternating current motors, per se. 322, Electricity: Single Generator Systems, appropriate subclasses for alternating current generator control systems.
In Class 322 classification is not determined by whether the generator output is AC or DC and the appropriate subclass would depend on the particular control or response of the generator.
