Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2023057734
Kind Code:
A
Abstract:
To provide a rotary electric machine capable of improving a degree of freedom of magnetic sensor arrangement while suppressing an increase in the number of components.SOLUTION: A rotary electric machine comprises: a rotor 20 provided with permanent magnets 23 embedded respectively in magnet housing holes 24 in a rotor core 22; a stator for applying rotating magnetic field to the rotor 20; and a magnetic sensor 30 for detecting rotation information of the rotor 20. The permanent magnets 23 have a folded shape protruding inward a radial direction of the rotor 20. The magnetic sensor 30 is configured to face the permanent magnets 23 so as to be able to detect a magnetic flux of the permanent magnets 23.SELECTED DRAWING: Figure 3
