Danfoss OMVS Series Motor | OMVS630 151B3128 OMVS800 151B3129 | Short Heavy Duty Motor

Danfoss OMVS Series (151B-) Ultra-Heavy Duty Short Motors

Product Overview: The Danfoss OMVS Series (151B- sequence) represents the pinnacle of power density within the orbital motor family. This category highlights the most powerful high-displacement models: OMVS 630 (151B3128) and the massive OMVS 800 (151B3129). Designed with a specialized Short/Bearingless architecture, these motors omit output bearings for direct integration into large planetary gearboxes, heavy-duty material mixers, or marine thrusters. Combined with Disc Valve technology, the OMVS series delivers staggering industrial-grade power within an incredibly compact footprint.

Key Technical Advantages:

• Elite Integration Capability: The bearingless “Short Motor” design allows for seamless integration into host machinery, leveraging the host’s bearing system to achieve maximum compactness and reduce total equipment weight.

• Peak Torque Performance: Utilizing optimized Geroler® roller set geometry, these motors provide smooth, pulse-free Low Speed High Torque (LSHT) performance even at massive 630cc or 800cc displacements.

• Precision Disc Valve System: The independent valve plate automatically compensates for wear, ensuring superior volumetric efficiency and minimized energy loss under high-pressure and frequent reversing cycles.

• Industrial Sealing Integrity: Equipped with high-performance sealing components designed to handle significant back-pressures and harsh outdoor industrial environments.

• Technical Spec Decoding:

  • 151B3128 (OMVS 630): A balanced powerhouse offering a blend of heavy-duty torque and operational speed.

  • 151B3129 (OMVS 800): The maximum displacement in the series, engineered for extreme heavy-load traction and pushing applications.
