Because synchronous motors can operate at advanced power factors by adjusting the excitation current, it is beneficial to improve the power factor of the power grid. Therefore, large equipment, such as large blowers, water pumps, ball mills, compressors, rolling mills, etc., are often driven by synchronous motors. This advantage is particularly prominent when low-speed large equipment uses synchronous motors. In addition, the speed of the synchronous motor is completely determined by the power frequency. When the frequency is constant, the speed of the motor is also constant, and it does not change with the load. This feature is of great significance in certain transmission systems, especially multi-machine synchronous transmission systems and precision speed regulation and speed stabilization systems. The running stability of synchronous motors is also relatively high. Synchronous motors generally operate in an over-excited state, and their overload capacity is greater than that of corresponding asynchronous motors. The torque of an asynchronous motor is proportional to the square of the voltage, while the torque of a synchronous motor is determined by the product of the voltage and the internal electromotive force generated by the motor's exciting current, which is only proportional to the first power of the voltage. When the grid voltage suddenly drops to about 80% of the rated value, the torque of the asynchronous motor often drops to about 64% and stops running because it does not move the load; while the torque of the synchronous motor does not drop much, it can also be forced by Excitation to ensure stable operation of the motor
