There are three main modes of operation for synchronous motor operation: generator, motor and compensator.

Playing the role of a generator is the most important mode of operation of a synchronous motor.

Operation as a motor is another important mode of operation of a synchronous motor. You can adjust the power factor of a synchronous motor. Without speed adjustment, you can improve operating efficiency by using a large synchronous electric motor. Small synchronous motors are beginning to find more applications in variable frequency speed control systems.

The synchronous motor can also be connected to the grid as a synchronous compensator. No mechanical load is applied to the motor at this time. The excitation current from the rotor is tuned to send the required inductive or capacitive reactive power onto the grid, with the goal of improving the grid force or regulating the voltage. Of the grid.
