Vertical Motor Load Testing at MENZEL

MENZEL now offers vertical motor load testing: realistic, manufacturer-independent, and compliant with international standards.

Vertically installed electric motors are subject to specific mechanical and thermal loads that differ significantly from those in horizontal configurations. Gravity acts directly on the bearings, shaft, and, where applicable, the brush gear, affecting wear, vibration behavior, and thermal performance. In many applications, including pumps, mills, and marine propulsion systems, vertical installation is standard. Testing under realistic conditions is therefore essential.

To meet these requirements, MENZEL now offers vertical load testing in addition to its proven horizontal test procedures. Tests are carried out under actual mounting conditions and enable comprehensive evaluation of both mechanical and electrical properties regardless of motor type or manufacturer.

Extended Testing Parameters for Vertical Configurations

In addition to standard electrical measurements, vertical testing includes analysis of bearing loads, bearing temperature rise, axial and radial force distribution, and vibration behavior. A key focus lies on the influence of vertical orientation on bearing performance. We manufacture all required adapters and clamping fixtures in-house, tailored to a wide range of motor designs.

Power is supplied via precisely controlled frequency converters, allowing various load conditions to be simulated. Test sequences are operated manually to ensure flexibility for different motor configurations. All measurement data is recorded, evaluated, and documented using our proprietary test software in accordance with IEC / IEEE standards – enabling transparent and traceable analysis.

Vertical load testing provides reliable insights into operational safety, supports repair assessment, and helps prevent failures during operation. It plays a key role in quality assurance and enables targeted maintenance planning for vertically mounted motors.
