Company Profile & Manufacturing Heritage

German Industrial Motor Manufacturing with Personal Engineering Support

At MENZEL Elektromotoren, we place industrial plant operators and their unique drive requirements at the core of our engineering process. Operating out of state-of-the-art facilities in Hennigsdorf near Berlin, Germany, MENZEL has delivered rugged, reliable industrial electric machines to heavy industries across the globe for nearly a century.

From cement works, steel mills, paper factories, and mine shafts to chemical process plants and power stations, our high-voltage and low-voltage electric motors are designed for continuous heavy-duty operation under extreme environmental conditions.

Comprehensive Electric Motor Manufacturing Portfolio

Our engineering team manufactures and customizes heavy-duty industrial electric motors according to strict international standards including IEC/EN 60034, VDE, DIN, and ISO:

Asynchronous Squirrel Cage Motors: Available in cooling classes IC 01, IC 411, IC 611, IC 81W, and IC 511. Engineered for continuous efficiency, low maintenance, and high structural rigidity up to 25 MW.
Asynchronous Slip Ring Motors: Specialized drives for high starting torque and limited start-up currents. Ideal for cement mills, shredders, mine ventilation, hoist drives, and heavy crushers.
Industrial DC Motors: High-torque direct current motors up to 2,000 kW and 1,000 V for rolling mills, extruders, cable car drives, dynamic test stands, and variable speed processes.
Special & Custom Replicas: 100% mechanically and electrically interchangeable 1:1 replicas for obsolete or legacy motors, matching existing foot dimensions, shaft centers, and terminal box positions without structural plant modifications.
In-House Manufacturing

Dual Heavy-Duty Clamping Fields: Measuring 12 x 5 m and 9 x 3 m with overhead crane capacity of 80 tons (7.5 m hook elevation above testing beds).
Vertical Testing Setup: Angular gearbox systems enabling full vertical axis testing for IM V1, IM V10, and IM 311 motor configurations.
Thermal Climate Chamber: Integrated 4.5 x 3 m thermal tent simulating high ambient temperature conditions for tropical or high-heat plant installations.
Live Customer Observation Lounge: Overseas procurement teams and consulting engineers are invited to witness live Factory Acceptance Tests (FAT) directly from our soundproof workstation suite.
Expert Engineering Support

Technical Consulting & Customized Drive Engineering

Maximum operational reliability is only achieved through exact matching of electrical and mechanical drive parameters. Our in-house engineering team provides expert guidance for demanding industrial projects worldwide.

Whether analyzing grid voltage drops during motor startup, matching torque-speed curves for heavy mill applications, or retrofitting legacy equipment in restricted spaces, MENZEL engineers provide direct, solution-oriented assistance from initial enquiry through commissioning.

Grid & Startup Optimization: We evaluate mains supply capacity, DOL vs. soft-starter or VFD operation to eliminate grid disturbance.
Cooling Method Customization: Engineering across all cooling systems: IC 01 (Open ventilated), IC 411 / IC 416 (Rib-cooled), IC 611 / IC 616 (Air-to-Air heat exchanger), IC 81W / IC 86W (Air-to-Water heat exchanger), and IC 511 (Tube-cooled).
Direct Mechanical Retrofitting: Adaptation of mounting flanges, shaft dimensions, terminal box locations, and cooling ducts for drop-in replacements.

Lead Engineer Oversight

Our technical engineering division, directed by Jörg Waschek (Head of Engineering Department), ensures that every custom drive design meets strict mechanical tolerances and electrical load characteristics prior to manufacturing release.

Fast engineering feedback and detailed technical dimensional drawings provided for every project quote.
