ent machine, when it is . HAWKINS ELECTRICITY remembered that the direction of rotation of the direct currentseries motor is independent of the direction of the voltage applied. At any moment the torque will be proportional to the productof the current and the flux which it is at that moment… … Fig. l.*S7.—Diagram of single phase series commutator motor. It is practically the sameas the series direct current motor, with the exception that all the aetal of the magneticcrcuit must be laminated. are not to be too high, the torque will be proportional simply totlie square of the current,…
