In a synchronous motor hunting occurs due to
WebThe Hunting process occurs in a synchronous motor as well as in synchronous generators if an abrupt change in load occurs. The steady state or stable operation of a synchronous … WebMar 11, 2024 · In conclusion, hunting is a phenomenon that occurs in synchronous motors when the motor oscillates in speed in response to changes in load. Hunting can be caused by a number of factors, including load imbalances, variations in power supply frequency, and improper tuning of the motor.
