| All Motor Test systems are available as manual, semi automatic or fully automatic versions. Systems include performance test and vibration test capabilities and optional: |
 |
• |
Insulation test |
|
• |
Assembly balancing |
|
• |
Auxiliary test |
Performance and vibration are tested by PI and VAD methods (Parameter Identification and Vibro-Acoustic Diagnostics). The PI system is able to give a precise accept/reject decision and motor diagnosis to identify electric and mechanical motor faults. The PI test technique offers completely new features for motor testing with important economical advantages:
The diagnostic capability and the statistical process control (SPC) enable immediate correction during production.
material faults for magnets, core stack, brushes
manufacturing faults for windings, commutator surfaces or welding points, and
assembling faults like missing parts or misaligned bearings are reliably recognized.

|
• |
Performance testing of permanent magnet motors without load coupling by means of parameter identification method. |
|
• |
The evaluation of all characteristic electrical, mechanical and vibro-acoustic parameters of the motors under test enables documentation of test data according ISO 9000 requirements. |
|
• |
The learning capability of the diagnostic system enables a flexible adjustment of quality set points. |
|
• |
The operation costs are reduced due to high testing speed and full automation. |
PI test systems are designed for easy operation. The hardware of the test system guarantees high reliability as its components are designed for an industrial environment. Companies around the world are working with Schenck PI systems for quality assurance. References to the systems in use for almost all types of electrical motors are available upon request. |
