Thermal modeling tools
Rotating electrical machines — Simulation of thermal behavior

Thermal modeling tools are increasingly used for the design of new machines associated with non-sinusoidal power supplies. A validated software tool provides access to points that cannot be reached experimentally. Similarly, simulations of behavior in extreme situations (high loads and severe ambient conditions) do not jeopardize a real motor.

The validation of these tools is particularly complex. Experimentation and simulation are totally inseparable. Figure 3 shows why it is preferable to combine two experimental phases with two simulation phases to calibrate a model. The greater the distance between the induced temperatures for the same reference points, the wider the range of validity of...
