3D Finite Element Computation of Axial Flux in Induction Machine
Abstract
In the paper results of finite-elementcalculations of the electromagnetic field in a squirrel-cage
induction motor with particular reference to the shaft flux
were presented. A three-dimensional field-circuit model of
the 300 kW induction motor was developed taking into
account supplying the stator winding from the voltage
source and the rotary motion of the rotor. Distribution of
axial and radial components of the magnetic flux density in
the end-winding region and the bearing region as well as
transient waveforms of the shaft flux were computed at the
initial period of the motor start-up.
