PROBLEM TO BE SOLVED: To increase acceleratable load torque by relieving a goerges phenomenon at the time of induction starting. SOLUTION: By setting the cross section of an armature winding 13b of one of three slots at every pole and every phase so as to be larger than those of armature windings 13a of the other slots, the whole electrical resistance of the armature windings 13a, 13b is set so as to be smaller than the electrical resistance of the armature winding in an induction motor of which the outside- diameter dimension and axial dimension are the same and of which the synchronous output is equal.
