Document Type and Number:
Japanese Patent JP2022146759
Kind Code:
A
Abstract:
To provide a rotary electric machine capable of estimating a rotation angle without having to align a permanent magnet to its initial location even for the rotary electric machine including a rotor that does not have magnetic saliency.SOLUTION: A rotary electric machine 10 has a rotor 20 having no magnetic saliency and a stator 14. The rotary electric machine 10 has a saliency ratio of 1.03 or more, which is the ratio of the inductance of a d-axis of the rotary electric machine 10 to the inductance of a q-axis.SELECTED DRAWING: Figure 2
