End-Of-Line Testing Of Electric Motors

Insulation testing is usually repeated in the final phase of motor testing. This can be performed using traditional techniques such as insulation resistance measurement, dielectric strength test (Hi-Pot), surge test or partial discharge measurements. This step is critical in ensuring that assembly operations have not compromised the integrity of the electrical insulation.

However, complete motor quality control also includes other functional tests aimed at evaluating key parameters, such as:

• Vibration and Noise (NVH testing)
• Back EMF
• Friction and iron losses
• No Load test
• Load test

and many other essential performance characteristics.

To meet the needs of the various stages in the life cycle of electric motors, Marposs E.D.C. has developed two distinct lines of functional test systems:

• The AMT320/W series is designed for use in production environments and is ideal for automatic end-of-line testing. These modular and configurable systems can adapt to different types of motors and line layouts, ensuring high performance and reliability in production.
• The ATC320/W is the most suitable solution for laboratory and R&D applications. This version is optimised for characterisation, validation and analysis activities on prototypes, offering maximum flexibility in test parameters and usage scenarios.
