Steady-state operation, the rotor speed and grid frequency has a constant relationship between n?ns?60f/p, ns known as the synchronous speed. If the frequency of the grid is constant, then the steady-state synchronous motor speed constant constant and independent of the size of the load. -Regardless of the size of the load, as long as the step does not lose speed will not change.
