BM2 Hydraulic Gerotor Motor | BM2-50 to BM2-500 | HMT BM1 BM2W Orbital Motor

LIC Hydraulic offers the BM2 Series (HMT/Orbital Motor), a robust mid-range hydraulic motor utilizing disc valve distribution technology. Engineered for efficiency and durability, the BM2 series covers a wide displacement range from 50cc to 500cc. Its Geroler gear set design with internal rollers reduces friction, ensuring high starting torque and smooth operation at low speeds. Whether you need the standard BM2, the BM2W wheel motor for direct vehicle drive, or the BM1 for compact tasks, our motors provide a reliable, cost-effective alternative to world-leading brands.

Technical Specifications (Bulleted List)

• Series: BM2 / HMT / BM2W (Wheel Mount)

• Displacements: $50, 63, 80, 100, 125, 160, 200, 250, 315, 400, 500\text{ cc/rev}$

• Max. Pressure: Continuous $17.5\text{ MPa}$ ($2538\text{ PSI}$), Intermittent $20\text{ MPa}$.

• Max. Torque: Up to $1000\text{ N}\cdot\text{m}$ for the BM2-500 model.

• Speed Range: Smooth operation from $5\text{ rpm}$ up to $800\text{ rpm}$ (depending on size).

Key Technical Advantages

• Disc Valve Technology: Automatically compensates for wear to maintain high volumetric efficiency and consistent performance over long service intervals.

• High-Pressure Shaft Seal: Designed to handle high backpressures, allowing multiple motors to be connected in series without an external drain line in moderate applications.

• Superior Low-Speed Stability: The Geroler design ensures that even at the lowest flow rates, the motor provides steady torque without “cogging” or vibration.

• Interchangeable Design: Dimensions and mounting interfaces are standardized to directly replace Eaton Char-Lynn 2000 series, Danfoss OMS, and White RE series motors.

Application Areas

• Mobile Hydraulics: Wheel drives for skid steers, salt spreaders, and mini-excavators.

• Maritime: Fishing net haulers, deck winches, and capstans.

• Forestry: Wood splitters, saw feeds, and log loaders.

Expert Maintenance Tips

• Case Drain Management: For applications with frequent reversing or high return line pressure, always use the case drain port to ensure the shaft seal remains intact.

• Filtration Standard: Keep your system fluid clean to $ISO\text{ 19/16}$ or better. Particles are the primary cause of disc valve scoring and loss of efficiency.

• Radial Load Limits: If using the motor to drive a heavy chain or gear directly, ensure the radial load does not exceed the bearing capacity (check technical curves for the specific BM2 model).
