Transient

Positioning and objective

The aim of “Characterization – Thermal – Motor & Generator – Transient” test is to evaluate the impact of electromagnetic performance on thermal behavior of the machine in a transient mode.

A thermal working point defined by a speed and a set of losses can be considered to compute the temperature charts and the main thermal parameters.

In addition to that, a maximum evaluation duration and a time step are added as inputs to set the transient mode.

This test helps to answer the following questions:
  • Can the machine operate at the targeted working point without any overheating? Yes / No
  • Can the different kinds of proposed cooling help to reach good performance? Yes / No
  • How long does it take to reach the thermal steady state and what are the thermal time constants of the machine?

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