The results of experimental and theoretical investigations of open circuit tooth ripple losses in slotted laminated poles of rotating electrical machines with amortisseur windings are presented. A laboratory machine model developed for this investigation is described. Both a Poynting vector method based on the electronic multiplication of electric and(More)
An integral equation formulation is obtained for the solution of electric and magnetic polarization in the material body subjected to external excitations. Numerical treatment of saturable magnetic field problems is facilitated by the introduction of a function called 'co-reluctivity' to describe the property of the magnetic material. The Gauss-Seidel(More)
