The BM3 series is a high-performance disc valve orbital hydraulic motor utilizing an advanced Geroler gear set design. Unlike smaller spool valve motors that use the output shaft itself to distribute oil, the BM3 features a dedicated, hydraulically balanced disc distribution valve driven by a separate drive link. This separation significantly improves volumetric and mechanical efficiency, provides smoother rotation under extreme low speeds, and allows the motor to withstand higher operating pressures and larger external loads.
Disc Valve Distribution: The independent disc valve self-compensates for wear over time, ensuring tight sealing, consistent torque delivery, and minimal internal oil slippage under prolonged high-pressure use.
Geroler Rolling Mechanism: Built with precision steel rollers on the outer ring teeth to minimize start-up friction, damp structural vibrations, and ensure reliable continuous mechanical efficiency under heavy-duty cyclic reversals.
Heavy-Duty Tapered Roller Bearings: The output shaft assembly is supported by robust tapered roller bearings. This allows the BM3 to handle significant radial and axial forces directly, making it perfect for driving heavy sprockets, vehicle wheels, or winches without needing auxiliary bearing blocks.
High-Pressure Shaft Seal: Fitted with an upgraded dynamic shaft seal capable of handling high backpressures, allowing flexible series or parallel plumbing configurations.
Independent Case Drain: Features a standard external third-line case drain port to relieve internal body cavity pressure, protecting the shaft seal from pressure spikes and ensuring long service life.
| Parameter | Range / Value | Metric & US Units | Notes |
|---|---|---|---|
| Displacement | 100 ~ 500 | cc/rev (cm³/rev) | Standard displacement options include 100, 125, 160, 200, 250, 315, 400, 500. |
| Max. Speed | 5 ~ 750 | RPM | 100cc small displacement can reach 750 RPM; 500cc large displacement max continuous speed approx. 150 RPM. |
| Max. Continuous Torque | 240 ~ 850 | N·m | Medium & large displacement (250cc-400cc) can steadily output 600-850 N·m under continuous operation. |
| Max. Intermittent Torque | 320 ~ 1080 | N·m | Peak torque allowed during startup instant, overload or impact load. |
| Max. Continuous Pressure | 140 ~ 200 | bar (approx. 2030 ~ 2900 psi) | 100cc-250cc models withstand up to 200 bar continuously; pressure drops gradually to 140 cc as displacement increases. |
| Max. Intermittent Pressure | 175 ~ 225 | bar (approx. 2540 ~ 3260 psi) | Maximum instantaneous pressure peak during system shifting, braking or temporary overload. |
| Max. Peak Pressure | 210 ~ 250 | bar (approx. 3050 ~ 3625 psi) | Ultimate impact pressure the system can withstand within extremely short seconds. |
| Max. Oil Flow | 60 ~ 75 | L/min (approx. 16 ~ 20 US gpm) | Max recommended continuous input flow for hydraulic motor; large displacement models usually support higher flow rate. |
| Max. Output Power | 15.0 ~ 30.0 | kW | Medium-high power grade, capable of output up to 30 kW under high pressure & heavy load conditions. |
