Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/212867
Kind Code:
A1
Abstract:
According to the present invention, a permanent magnet to be inserted in a permanent magnet hole formed in a rotor core is fixed by an interposed member, and the interposed member is intended for inhibiting temperature rise in the permanent magnet by preventing the permanent magnet from exiting the permanent magnet storage hole of the rotor core and by decreasing the thermal resistance from the magnet to the rotor core. Provided is a rotary electric machine comprising a rotor and a stator, wherein: the rotor is provided with a rotary shaft, a permanent magnet, a rotor core forming a storage part for storing the permanent magnet, and an interposed member that fixes the permanent magnet in the storage part, and that has a fixing surface on the permanent magnet side and a shear surface on the inner surface side of the storage part; and the rotor core is in contact with the permanent magnet at a surface thereof on which the interposed member is not fixed.
