How to find magnetic field in squirrel cage induction motor?
Answer Typical applications Geometry
Given
Solution
The nonlinear magnetization curves of the laminations and of the shaft are given in the "Data" file. Current density in the coils (Cu1,Cu2,Cu3) is for the rated power of the motor. The model is useful for other operating points too.

Simulation problem
Problem Type
Plane-parallel problem of DC magnetics.
Rated power Pn=1.5 kW,
Rotating speed Nn=1390 rpm,
Voltage Un=380 V,
Frequency f=50 Hz
Study is made on a half pole length, because of the symmetry of the machine.
