- Abstract (EN)
- For predicting the performance characteristics of highly utilized induction machines, commonly finite element analysis (FEA) is applied. If only the stationary behavior is of interest, both time-harmonic and transient calculations are feasible. Both procedures offer benefits and drawbacks regarding precision and computing time. In this paper the stationary torque-slip-characteristic of a squirrel cage induction machine for electric vehicle application is calculated by means of time-harmonic and transient FEA. The simulation results are compared to measurements taken on the test bench. For low saturation levels the time-harmonic and transient simulation produce nearly equivalent stationary torque results. For high saturation levels, the commonly used approach for nonlinear time-harmonic calculation is to use a corrected magnetization curve. It is shown that the assumption of sinusoidal time variation of the magnetic field strength usually made in this case results in a torque error increasing with the saturation level for the time-harmonic calculation.
