Abstract
501,866. A.C. commutator motors; induction regulators. SPENCER, M. C. Feb. 21, 1938, No. 6380. Convention date, Feb. 19, 1937. [Classes 35 and 38 (ii)] A polyphase motor having stator windings connected to the supply has the commutator brushes connected to the series connected secondary windings of two or more single phase induction regulators, the series connected primary windings of which are connected to the supply. In the form shown, the brushes 21-23 are connected to the secondary windings 27, 28 of two induction regulators, the primary windings 29, 30 of which are connected to the supply 11-13 and may be on cores carried by a common shaft in a housing containing both secondary cores. Each primary core may also carry a short-circuited winding 35, 36.
