Abstract
A rotary electric machine includes: a shaft that rotates about an axial direction; a rotor that is disposed around the shaft and that includes a rotor core and a plurality of magnets provided in the rotor core; a stator that is disposed around the rotor and that includes a stator core and a stator coil provided in the stator core; a magnetic flux short circuit plate that is disposed so as to face the rotor core in the axial direction and that moves in the axial direction; a biasing member that biases the magnetic flux short circuit plate to a side away from the rotor core; a holding member that holds the biasing member; and a fixing member that fixes the holding member to the shaft. Further, a strength of a material of the fixing member is higher than a strength of a material of the holding member.
