Abstract
This paper presents a mathematical model of
magnetic fields in an induction motor. A two-dimensional
nonlinear time-stepping finite element method (FEM) is
used for the electromagnetic field analysis in an induction
machine operating with full load steady-state rotor
movement. To solve this time-dependent system, a stepby-
step numerical integration of the backward difference
algorithm is applied. In addition, the Newton-Raphson
(N-R) method is employed to handle the nonlinearities of
the system equation. To evaluate its use, a three-phase,
four-pole 5-hp squirrel-cage induction motor with double
layer winding was tested. As a result, the magnetic flux
distribution through the cross-sectional area of the
induction motor was well described, graphically, using
the flux line plot. Moreover, space and time
electromagnetic forces resulting from the magnetic flux
were also analyzed. |
