Thermal steady state

1. Positioning and objective

The aim of “Characterization – Thermal – Motor & Generator – Steady state” test is to evaluate the impact of electromagnetic performance on thermal behavior of the machine.

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. The inputs describing the thermal working point can be set manually or imported from electromagnetic tests that were previously solved.

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

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

2. User inputs

The main inputs are the losses to be considered for evaluating the corresponding thermal behavior of the machine and the speed.

3. Main outputs

Here are the main results available:

• Temperature charts – radial and axial view
• Temperature table
• Main thermal parameters
