hase Motor (Repulsion Motor withVoltage applied to the Rotor Brushes).This machine is similar to the Atkinsonrepulsion motor, save that an auxiliary emfis fed into the rotor, which will in generalbe in phase with the emf across the inducingcoil, though it may be convenient to varyits phase somewhat… … Fig. 21.—Funga8 Series Induction-conduction Single-phase Motor It has been pointed out that the commuta-tion of the Thomson repulsion motor at syn-chronism is equivalent to that of a cc motor.The net effect of the auxiliary rotor emfused in this motor is to change the speed ofbest commutation from…
