摘要： The present invention aims to strengthen the durability against the centrifugal force acted on a rotor of a synchronous induction motor to increase reliability of the motor. The rotor for the synchronous induction motor of the invention includes: at least one pair of slits forming salient poles in a direction of a d axis in which the magnetic flux can flow easily and in a direction of a q axis in which the magnetic flux can hardly flow; and plural slots located at an outer circumference side of the slits and connected to at least one end of the slits in the direction of the d axis to generate induction torque. Conductive material is filled in at least the slots among the slits and the slots. The rotor is provided with a rotor cover made of a non-magnetic body as a reinforcing member to strengthen the rotor against the centrifugal force acted at the outer side of the direction of a diameter.

摘要： When an inverter circuit is driven at a predetermined driving frequency, an amount of current change per predetermined period of time of an input current or a coil current is detected, and a heating period from a start of control until the amount of current change becomes a set value or less is measured. Then, the inverter circuit is controlled to reduce high frequency power to be supplied to a heating coil in accordance with a length of the measured heating period.
