Squirrel-cage induction motor simulation

QuickField simulation example

Problem Type
Plane-parallel problem of nonlinear magnetostatics.

Geometry:
squirrel-cage induction motor

Given
Rated power Pn=1.5 kW,
Rotating speed Nn=1390 rpm,
Voltage Un=380 V,
Frequency f=50 Hz

Solution
Study is made on a half pole length, because of the symmetry of the machine.

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.

Results
