Thermal - Fitting

Positioning and objective

The aim of the “Characterization – Thermal – Motor & Generator – Fitting” test is based on a steady state thermal computation.

Whatever the considered machine, FluxMotor creates a thermal network based on the machine topology design. However, if needed, it is possible to adjust the thermal resistances with some calibration factors (X-Factors, for external cooling as well as internal cooling) to be consistent with the measurement results for instance. This has an impact on the resulting temperatures one gets in steady state or transient mode.

The user can adjust the calibration factors, step by step, and evaluate the final temperatures by performing a manual iterative process.

This can be used either when the users want to impose the reference temperatures that are coming from measurements or when the users want to keep the same temperatures after a modification of the internal thermal architecture model.

With the test Characterization-Thermal-Motor&Generator-Fitting, the calibration for the X-factors is fully automatic. The user must target the temperatures to be obtained and the X-Factors that can be used to reach this goal. As a result, one gets X-Factors values to be applied for reaching the targeted temperatures.

The following table helps to classify the test: “Characterization – Thermal – Motor & Generator – Fitting”.

User inputs

First, the targeted temperatures and the calibration factors to be used for the calibration. Then, the main inputs are the losses to be considered for evaluating the corresponding thermal behavior of the machine and the speed.
