Load Test with Coupled Machines — Thessaloniki Facility

At our premises in Thessaloniki, we recently performed a full load test using two identical electric motors, mechanically coupled to simulate real operating conditions.

This testing method — often referred to as back-to-back testing — allows us to evaluate the performance, thermal behavior, vibration response, and mechanical balance of the tested unit with high accuracy and full control over load parameters.

The setup involved:

• Two matched machines, operating as motor and generator

• Controlled load conditions, monitored throughout the test

• Real-time data acquisition, including current, voltage, torque, temperature, and vibration

This procedure is used to confirm both the quality of the motor under test and the robustness of its application-specific configuration, especially in demanding industrial environments. The test helps us verify alignment, cooling performance, mechanical integrity, and the response under sustained load — long before the motor is ever installed on-site.

Tests like these are a key part of our commitment to ensuring trouble-free commissioning and maximum reliability in the field.
