HUNTING For satisfactory operation of a synchronous motor, the mechanical speed of the rotor should be equal to the stator field. Any departure from this condition will upset the synchronizing forces that tend to maintain the equality. The oscillation of rotor about its final equilibrium position is called hunting. When synchronous machine is coupled with a system where torque variation contains harmonics, hunting pulls the machine out of step when the frequency of the torque component is equal to that of the frequency of free oscillations. | |
