The main motor Mi is started by the frequency-sensitive rheostat RFi
. After starting, it switches to the speed control system.
Part of the output power of the main motor is transmitted to
the production machinery, and the other part is converted into electric energy through the rectifier U and the auxiliary
unit (a motor-generator unit composed of M2 and G)
and sent back to the grid.
