Abstract

Formulas that have been derived are used for calculation of eddy current losses in square teeth. It is shown that, assuming that permeability and conductivity of iron are constant, the overall eddy current losses can be calculated as the sum of pulsation and surface losses. Directions have been given on how to calculate the overall teeth losses for all forms of teeth taking into consideration skin effect of flux in lamination, damping of teeth flux and factors of iron sheet and core processing.

Keywords

induction machines; eddy current losses; hysteresis losses; pulsation losses; surface losses
