DefinitionA <SCHRAGE MOTOR> is an <ALTERNATING CURRENT COMMUTATOR MOTOR> and a <POLYPHASE MACHINE> that is an alternating current commutator motor in which the rotor carries two windings, one of the windings receiving current from the supply by means of slip-rings while the other is connected to a commutator
The commutator carries two adjustable sets of brushes and supplies each of the separate phases on the stator with adjustable voltages, in order to attain a variation of speed and of the reactive power taken from the supply. IEV 411-33-22
