SYNCHRONOUS MACHINE WITH COMMON STAGE OF EXCITATION DEVICE FOR MOTOR/GENERATOR Russian patent published in 2019 - IPC H02K19/38 H02K11/42 H02K3/28 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Synchronous machine (100) has housing (110), shaft (115), main section (120) and excitation section (125). Main section (120) has stator winding (130), which is installed on the housing, and rotor winding (135), which is installed on the shaft. Excitation section has transformer (140) and rectifier (145). Transformer has primary winding (140A) installed on housing, and secondary winding (140B) installed on shaft. Rectifier is installed on shaft and rectifies output signal of secondary winding to provide supply of rectified output signal to rotor. Control unit (170) provides for supply of high-frequency control signal to primary winding. This signal is magnetically connected to the secondary winding, rectified and then supplied to the rotor to control operation of the synchronous machine.

EFFECT: higher stability of machine operation.
