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.
