The core characteristics and typical applications of BMM series cycloid hydraulic motors are comprehensively compiled from technical literature and manufacturer data：
Core features
Structural design
It adopts axial flow distribution or end-face flow distribution structure, which is compact in size and light in weight (for example, BMM-160 weighs only 6.7kg).
The built-in check valve design eliminates the need for an external oil drain pipe, simplifying the layout of the hydraulic system.

Performance parameters
Displacement range: 80-800 mL/r, covering small and medium torque requirements.
Working pressure: the rated pressure is 12-14 MPa, and the peak tolerance is 16-20 MPa.
Low-speed stability: the minimum stable speed is 5-10 rpm, which is suitable for heavy-duty start-up.

Technical advantage
The starting efficiency is as high as 90%, and the mechanical efficiency is 75-85%.
It has strong short-term overload capacity and can withstand radial/axial composite loads (with bearing models).
Typical application scenarios
Agricultural machinery: harvester drive, spreader (BMM-80/160).
Engineering equipment: tubing pliers, bolt drilling rig (BMM-315/400).
Shipbuilding industry: fishing gear, net collection, winch (BMM-200/250).
