ANALYSIS OF THE CORES OF INDUCTION-MOTORS WITH STATORS MADE FROM CUT LAMINATIONS

Analytical methods for yoke magnetomotive force, magnetization current and basic core loss calculation for induction motors with tangential- fan acid multiplanar cores are suggested. Analytical relationships are given which allow for a variable cross-section of yoke elements at th e design stage. Comparison of calculated results with the results of n umerical modelling of the magnetic field in the stator yoke for varyin g saturation levels is given. Some recommendations are made for optimu m stator yoke configuration selection and for the scope of analytical relationships.
