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.

摘要： The conventional slit is symmetrically aligned with respect to the q-axis that is a direction where the magnetic flux is difficult to flow. Because of this, the generated magnetic flux must jump over the slit, whereas its jumping over position being dependent on the rotation of the rotor. This hinders a flow of the magnetic flux. This has caused problems such as making the efficiency worse and increasing the losses. Therefore, at least one pair of slits is constructed on the rotor, which forms the salient pole so as to obtain the d-axis (where the magnetic flux is easy to flow) and the q-axis (where the magnetic flux is difficult to flow). A low magnetic resistance parts having a small magnetic resistance are formed at these slits that are asymmetrically aligned with respect to the q-axis.
摘要翻译： 传统的狭缝相对于作为磁通难以流动的方向的q轴对称地排列。 因此，所产生的磁通必须跳过狭缝，而其跳跃位置取决于转子的旋转。 这阻碍了磁通量的流动。 这导致了诸如使效率更差并增加损失的问题。 因此，在转子上形成至少一对狭缝，形成凸极以获得d轴（其中磁通易于流动）和q轴（其中磁通难以达到 流）。 在相对于q轴不对称排列的这些狭缝处形成具有小磁阻的低磁阻部分。
