DESCRIPTION
The types of tests that can be performed depend on the construction technology, size and final application of the motor. Each system can include electrical and functional tests to ensure comprehensive and reliable final testing.
For R&D and laboratory applications, Marposs E.D.C. offers the dedicated ATC320/W version, which is designed to support the characterisation, validation, and prototyping of electric motors. Each system is developed according to the customer's specific needs.
The test system can be configured with several major components, including:
- an AMT320/W computerised control unit, which is responsible for complete testing process management;
- an Active or Passive Brake, which is necessary for performing load tests;
- the Power Supply Unit (PSU320) integrates the power distribution unit (PDU) and the DC power supply for the inverter of the motor under test and the active brake. The DC power supply can power the device under test (DUT) and regenerate braking energy directly to the grid.
The AMT320/W is an extremely versatile system designed for testing a wide variety of electric motors. It supports single-phase and three-phase AC motors, DC motors (including windscreen wiper motors), brushless motors, geared motors, swing and sliding gate motors, shutter and blind motors, and specialised motors such as synchronous reluctance motors.
Marposs E.D.C. can also supply customised systems for testing multiple types of motor within the same facility. These solutions are ideal for companies that produce small volumes of motors and require a flexible, reconfigurable system that can adapt to a diverse range of products.
Available testing solutions
The AMT320/W system is designed to perform a wide range of tests aimed at the comprehensive characterisation of motors' electrical and functional performance. Some of the main tests available include:
- Electrical insulation tests and Partial Discharge measurements
- Safety tests
- No-load test
- Load test
- Winding temperature rise test
- Start-up test
- Motor characterisation
- Automatic calculation of efficiency and losses according to EN 60034-2-1
- BEMF (Back Electromotive Force) measurements with RMS and THD value indication
- NVH (Noise, Vibration, Harshness) test
- Rotation check
- Hall sensors, resolvers and encoders check
- Motor blocked test
- Cogging and Friction test
- Ld and Lq acquisition
The AMT320/W system from Marposs EDC offers a comprehensive range of solutions to meet all your electric motor testing needs.
BENEFITS
Opting for Marposs E.D.C.'s AMT320/W system means relying on a tried-and-tested, flexible solution designed to ensure operational continuity and consistent measurement accuracy.
Thanks to its well-established experience in motor testing and high design flexibility, Marposs E.D.C. is a reliable and effective partner in developing tailor-made solutions that can respond specifically to customer needs.
Marposs E.D.C. supports customers in adapting the testing system continuously to product evolution, offering modular upgrades and integration of new features at optimised cost and with high performance.
Attention is also paid to safety and ergonomic aspects to ensure a safe, efficient, and comfortable working environment for the operator.
Thanks to its extensive portfolio, Marposs E.D.C. can provide manual benches, which are ideal for small production batches, as well as semi-automatic solutions and fully automated lines dedicated to mass production.
VERSIONS
The AMT320/W is designed to offer flexible configurations to suit specific customer needs. Configurations can vary according to the following:
- Motor power: systems for motors up to 20 kW (with an integrated power supply) or up to 1 MW (with an external power supply).
- Use: It is designed for integration into fully automated lines or as a standalone operator test bench.
- Test bench structure: we offer a wide range of modular solutions, from single test benches to complex systems capable of handling two or more stations. These can be custom-designed for specific types of motors or applications. Configurations can include three-station rotary tables, safety light curtains and ergonomically and functionally optimised layouts that comply with industrial safety standards.
- Integration on automatic lines: in addition to stand-alone or semi-automated use, we can also provide fully automated test stations or islands designed for direct insertion into new or existing production lines. These solutions ensure high productivity, reliability, and business continuity in the most demanding industrial settings.
- AMT320/WF - Complete Fan Testing System: is a complete fan testing system designed for high-cadence production environments. It enables comprehensive electrical and functional testing, including speed measurement, direction of rotation control, and vibration analysis. The system can be integrated into automated production lines or supplied as a standalone station.
- AMT320/WP - End-of-Line Test System for Pumps: is an automatic system for testing pumps in a production environment. It can be configured for integration into automated production lines or for manual operation. As well as carrying out electrical tests on the motor, it allows the measurement and verification of important parameters such as flow rate, pressure, head, capacity, speed (RPM), torque and direction of rotation.
