Abstract
The present invention provides a rotary electric machine, in which it is possible to reduce the dimension of a casing in a direction along a rotation center line. The rotary electric machine comprises a magnet rotorrotating about a rotation center lineand one or more magnetic sensorsfor detecting leakage flux leaking out of the magnet rotor. The magnet rotorand a statorare received in a casing. A sensor receiving portionfor receiving the one or more magnetic sensorsis disposed in an outer wall portion of a side wall of the casinglocated in an extending direction of the rotation center lineof the magnet rotor. The one or more magnetic sensorsare received in the sensor receiving portion. The sensor receiving portionis disposed in a position that allows the one or more sensors to detect leakage flux leaking out of the magnet rotor
