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. WebUnder which of the following conditions hunting of synchronous motor is likely to occur ? A. Periodic variation of load B. Over-excitation C. Over-loading for long periods D. Small and …

WebP hys = Hysteresis losses; η = Hysteresis coefficient; B max = Maximum flux density; f = Supply frequency; V = Volume of the magnetic material; Eddy Current Loss: Eddy current loss occurs due to the current induced in the core of the synchronous motor. As we know, a varying magnetic field induces a current in a conductor and the core is made of iron which … Web⇒ Hunting in a synchronous motor takes place when supply voltage fluctuates when load varies when power factor is unity motor is under loaded ⇒ If the field of a synchronous motor is under-excited, the power factor will be zero unity lagging leading ⇒ The standard full-load power factor ratings for synchronous motors are zero or 0.8 leading bounty bars
