WebA Synchronous motor is a type of AC motor which runs at a constant speed, known as synchronous speed. The rotor in a synchronous motor always maintains synchronism … WebA Synchronous motor is a type of AC motor which runs at a constant speed, known as synchronous speed. The rotor in a synchronous motor always maintains synchronism with the rotating magnetic field of the stator. Even the load variations do not alter the motor’s synchronism. Hence, synchronous motors are used in constant speed applications.
WebMar 9, 2024 · The stability of the working speed is affected by the compressibility of air. However, the use of a gas-liquid linkage device provides satisfactory results. Due to a low working pressure of generally 0.31 MPa and the need to keep the structure size small, the total output force should not exceed 10 to 40 kN.
