Summary:To provide a rotary electric machine, a compressor, a refrigeration unit, and a vehicle, which diversify the control of the rotary electric machine.SOLUTION: A stator (20) includes: a stator core (30) provided with an armature slot (35a) and a field slot (35b); an armature winding (40) accommodated in the armature slot (35a); and a field winding (50) and a first field magnet (70) accommodated in the field slot (35b). The armature winding (40) generates a rotating magnetic field that rotates a rotor (10) by being supplied with an armature current (i40). The field winding (50) generates a field magnetic flux (M50) by being supplied with a field current (i50). The magnetic force of the first field magnet (70) can be changed by the field magnetic flux (M50).SELECTED DRAWING: Figure 1 【課題】回転電気機械の制御を多様化させる。【解決手段】固定子(20)は、電機子スロット(35a)と界磁スロット(35b)とが設けられた固定子コア(30)と、電機子スロット(35a)に収容される電機子巻線(40)と、界磁スロット(35b)に収容される界磁巻線(50)および第1界磁磁石(70)とを有する。電機子巻線(40)は、電機子電流(i40)が供給されることで回転子(10)を回転させる回転磁界を発生させる。界磁巻線(50)は、界磁電流(i50)が供給されることで界磁磁束(M50)を発生させる。第1界磁磁石(70)は、界磁磁束(M50)により磁力を変更可能である。【選択図】図1
