In a synchronous motor hunting occurs due to

WebHunting can occur in a synchronous motor due to the following reasons: 1. When the load on the shaft of a synchronous motor is suddenly increased or removed or a continuously … WebThe hunting can also occur in a synchronous generator. In this case also, due to sudden change in electrical output or mechanical input, oscillations are set up in the rotor called hunting, which can be prevented by providing damper winding in synchronous generator. Thanks for reading about “damper winding in synchronous motor”. ← Previous Post
