ALTERNATING CURRENT MOTORS 1,349 Since, as stated, commutator motors are similar to directcurrent motors, the question may be asked: Is it possible to run adirect current motor with alternating current? If the mainsleading to a direct current motor be reversed, the direction orrotation remains the… … Fig. 1,860.—Wagner single phase variable speed commutator motor. The commutator is ofthe regular horizontal type and the brushes remain in contact all the time. As the torqueof alternating motors varies directly as the square of the applied pressure, wide speetivariation may be obtained by varying…
