Abstract :
This paper presents a new method for estimation of rotor surface losses in small-to-medium capacity synchronous machines. In this study, the authors have proposed a method for estimating the slot ripple losses induced on the rotor surface. Also, we compared the damper systems using the finite-element method and verified the results by the measured data.
