Abstract
In this paper a YKK400-6
710KW induction motor is taken as an example.We create its 3D physical model and solve region
we boundary conditions and mathematical model are determined according to electromagnetic theories.The eddy loss in motor frame near end windings is calculated by using the numerical methods and find the method to reduce the additional loss of motor by changing the size and the components of the materials.
