Abstract
5153. Elektrizitõts-Akt.-Ges. vorm. W. Lahmeyer & Co. March 18, 1905, [date applied for under Patents Act, 1901]. Motors, controlling.-Asynchronous alternating- current motors a are regulated by coupling them with alternating-current commutator motors fed with current from the secondary winding of the asynchronous motor, further regulation being effected by shifting the brushes or by including a regulable series transformer in the stator circuit of, or otherwise regulating, the commutator motor.
