High-precision mechanical and electrical adaptations for heavy-duty industrial electric motors up to 25 MW & 13.8 kV.
MENZEL Elektromotoren is your expert for custom designs, mechanical modifications, and specialized drive conversions in industrial drive technology. When standard off-the-shelf electric motors fail to comply with existing mounting footprints, severe environmental constraints, or specific electrical grid parameters, our in-house engineering team delivers precision-engineered drop-in solutions up to 25 MW.
Whether your application requires a customized mounting flange, extended shaft dimensions, enhanced ingress protection ratings (up to IP67), or specialized cooling conversions, MENZEL executes all structural and electrical modifications directly within our modern Berlin factory.
From custom mechanical machining to advanced electrical re-engineering, MENZEL delivers custom solutions for all industrial requirements.
Precision manufacturing of custom flanges for vertical (V1) or horizontal installations, special shaft extensions, dual shaft ends, custom keyways, foot adapter plates, and modified mounting hole patterns to ensure exact drop-in fitment.
Conversion between cooling methods including open-circuit ventilation (IC 01/IC 06), surface rib cooling (IC 411/IC 416), air-to-air heat exchangers (IC 611), air-to-water heat exchangers (IC 81W), tube cooling (IC 511), and forced external ventilation units.
Installation of specialized PT100 temperature sensors in windings/bearings, SPM vibration monitoring sensors, optical shaft encoders, electromagnetic brakes, anti-condensation standstill heaters, custom terminal box positions, and rewinding.
Optimal drive reliability can only be achieved when the entire drive system is engineered with extreme technical precision. Backed by nearly 100 years of German engineering expertise, MENZEL’s in-house calculation engineers carefully analyze electrical grid conditions, starting behaviors, thermal dissipation, and mechanical loads to optimize every customized motor configuration.
Prior to dispatch, every modified motor undergoes comprehensive routine and full-load testing in our state-of-the-art test field (capable of testing up to 25 MW, 13.8 kV, and 2,300 kVA continuous duty). Overseas buyers and plant directors are welcome to observe performance testing live on-site in Berlin or via real-time video inspection.
"We deliver engineered drive reliability. Through rigorous quality testing, precision craftsmanship, and decades of practical engineering experience, MENZEL guarantees maximum uptime and long-term durability for heavy industrial installations worldwide."
