IM SQ 3PH

1. Preamble

In this document all the tests are described for both types of machines:

  • Induction Machines with Squirrel Cage – Inner Rotor
  • Induction Machines with Squirrel Cage – Outer Rotor

When the machines are illustrated with inner rotor, keep in mind that the conditions of test and methods of computation are the same.

One test allows to perform thermal computations for Induction Machines with Squirrel Cage – Inner Rotor.

2. Overview

The dedicated test environment (TEST area inside Motor Factory) enables users to assess motor performance.

Standard and relevant test portfolios are available. All the predefined tests are ready to be performed.

Relevant input parameters allow users to control test conditions.

Processes are based on optimization technology. All the results are automatically illustrated.

Tests associated with the convention of operating Motor are grouped into packages and classified into test families.

Test family Topology Package Convention Test
Characterization IMSQ – IR/OR Model Motor Basic
Characterization IMSQ – IR/OR Model Motor SSFR
Characterization IMSQ – IR (1) Thermal Motor & Generator Steady State
Working point IMSQ – IR/OR (1) Sine wave Motor U-f-N
Performance mapping IMSQ – IR/OR Sine wave Motor T(slip)
Mechanics IMSQ – IR (1)(2) NVH Motor Work. Pt. U-f-N
Mechanics IMSQ – IR (1)(2) NVH Motor Work. Pt. I-f-N
Mechanics IMSQ – IR (1)(2) NVH Motor Spectrogram - U-f-N
Mechanics IMSQ – IR (1)(2) NVH Motor Spectrogram - I-f-N
Note:

  1. The test (working point U-f-N, in motor mode is available for both topologies inner and outer rotor. However, the computation in steady state of the thermal behavior is available only for inner rotor topology.

    NVH tests are also available only for inner rotor topology.

  2. In the current version, NVH tests are available only in beta mode user level (See user preferences – Advanced tab)

  3. The tests are described in documents dedicated to each test family. Here is the list of available documents:
