Danfoss OMM Series Ultra-Compact Precision Micro Orbit Motors

Product Overview: The Danfoss OMM Series (151G- sequence) is an ultra-compact orbital hydraulic motor specifically engineered for space-constrained and precision applications. As the most lightweight member of the Danfoss family, this page highlights three essential models: OMM 12.5 (151G5041), OMM 32 (151G0006), and OMM 50 (151G0013). Despite its micro frame, the OMM series inherits the robust DNA of larger motors like the OMS and OMH, delivering reliable high-speed performance. It is the premier choice for small conveyors, machine tool spindle attachments, lawn care equipment, municipal sweeper brushes, and medical or industrial automation precision drives.

Key Technical Advantages:

• Ultra-Compact Footprint: Minimal physical dimensions allow for seamless integration into tight spaces where conventional motors cannot fit, significantly optimizing host machine layout.

• High-Speed Responsiveness: Optimized internal fluid channels ensure exceptional dynamic response and power stability even at high RPMs and low flow rates.

• Precision Spool Valve Technology: Features optimized spool valve logic for exact oil distribution, minimizing internal leakage and maximizing volumetric efficiency.

• High Back-Pressure Resilience: Equipped with premium shaft seals that handle significant back-pressure, simplifying hydraulic circuit design by reducing the need for complex drain lines.

• Technical Decoding:

  • 151G5041 (OMM 12.5): High-speed specialist, ideal for micro-drives requiring rapid rotational response.

  • 151G0006 (OMM 32): The versatile balance between compact size and consistent torque.

  • 151G0013 (OMM 50): The powerhouse of the micro series, providing maximum output within a miniature frame.
