Abstract

PURPOSE: To improve the synchronous characteristic and to increase the synchronizing torque of a squirrel-cage induction synchronous motor by narrowing a magnetic path of teeth of recess poles only at the part of the tooth corresponding to the inner slots of double squirrel-cage slots.
CONSTITUTION: Double squirrel-cage slots 2, 2' are formed on the outer periphery of a rotor core 1, slits 3 are formed, and projecting and recess poles 4, 5 are formed. The slot 2' formed at the pole 5 is widely formed in width at the inside with respect to the slot 2 formed at the pole 4, thereby narrowing the width of the tooth 6 to narrow the magnetic path of this part. Thus, the difference of the magnetic resistance of the magnetic path 8 of the pole 5 from the magnetic path 6 of the pole 4 is increased to increase a synchronous torque. Since the magnetic flux passes the outer periphery to generate a torque at the conductor in the outer slot at the time of starting, the starting characteristic is not reduced thereby.
