Abstract :
A series motor (single phase or 3 phase) having an armature winding with cross connectors permits a 2nd-pole operation for its rotor as an induction cage. Experimental investigations reveal that the preferred 2nd pole is a lower one. Six terminals are required for 3-phase and 4 for single-phase machines. With no additional winding in their stators, pole-changing windings in these machines provide an additional constant-speed characteristic besides a series one.
