(under the class definition) Subject matter in which the motor is an alternating-current commutation motor.
(1) Note. See Alternating-Current Commutating Motor, of the class definition for a definition of alternating current commutator motor. Such motors are commonly referred to as a "series a-c motors", a "universal motor", and an "a-c commutator motor".

43, for plural motor systems having alternating-current commutating motors with electrical synchronizing interconnections between the windings of the motors.
135, for linear-movement motor systems with commutating means for progressively energizing an a-c supplied field winding of the motor.
138, for a-c supplied motors having space-discharge devices operating as commutating devices for the several windings of the motor.
700+, for synchronous (AC motor systems where the motor is provided with commutators. 725+, for repulsion motor systems where the motor is provided with commutated windings.
737, and 738, for induction motor systems where the motor is provided with a commutated winding.
