ncrease in the magnetic leakage thus causedis not important, as the phase difference is avoided by the arrange-ment described. The most remarkable thing about the motor is the commutationof the current by a commutator formed of a ring closed on itself.It is natural that such a commutator is not at… … Fig. 167 Alternatingr Motors forms to the winding. This is correct, but by the arrangementdescribed the exciting current is already so reduced that this loss iswithout importance. In all induction motors the principle is the same. A primarycurrent sets up a secondary current by magnetic induction,…
