Inputs

Standard inputs ––––--

Speed

The speed of the machine to be considered.

Set of losses

The losses to be defined are the following ones:
  • Stator Joule losses
  • Stator iron losses
  • Magnet losses
  • Rotor iron losses
  • Mechanical losses

Time definition

The time during which the test is performed, defined by:
  • Max. evaluation duration
  • Time step

Description

The set of inputs can be imported from another test already performed in Motor Factory Test environment.

It can be current results or saved test results.

Then the duration of the evaluation and the time step must be defined.

Table 1. How to define a set of losses ?


1 Fill in the table to define the speed, all the losses to be considered, the max evaluation duration and the time step.
2 Click on the button “import” to import inputs corresponding to a solved test. All existing data of the selected test will be imported into the inputs of the thermal characterization. The data which does not exist in the outputs of the selected test are set to 0.
Table 2. Dialog box to select the test from which a set of losses must be imported


1 Selection of the test. Only solved tests are available in the drop-down list.
2 Current tests as well as saved tests can be selected.
3 When several working points are computed in the selected test, each of them can be selected to consider the corresponding losses.
4 The thermal settings of the referent test can be imported as well
Note: The imported data are the output data directly shown in the considered solved test. For some tests, some values are not defined (like for instance the Joule magnet losses or rotor iron losses). In that case, the corresponding input in transient thermal test will remain at the value existing before the import.

Advanced input ––––--

There are no advanced inputs required for this test.

Advice for use

Note: The resistance network identification of a machine is always done without any skew angle. This can bring some inaccuracy in the results for highly skewed machines.
