Description
BM6 Hydraulic Motor
The BM6 series hydraulic motor is a high-performance heavy-duty orbital geroler hydraulic motor with advanced end face distribution, upgraded and developed on the basis of the classic BM5 series. It is specially designed for high-demand low-speed, heavy-duty operation scenarios that require higher pressure, larger torque and more stable efficiency, integrating high power density, strong load-bearing capacity and intelligent adaptability. Widely applied in large-scale industrial equipment, heavy mining machinery, high-end marine equipment and other fields, it perfectly meets the operational needs of high-pressure, high-efficiency and long-time continuous work. Below is the complete technical specification, including model parameters, core features, performance data and application scenarios, helping you quickly select the suitable product.

Key Features of BM6 Series Hydraulic Motors
-
High-performance heavy-duty design, upgraded from the BM5 series, adopting advanced precision end face distribution technology and internal curve gear meshing principle, with higher power density and load-bearing capacity, fully meeting the high-pressure and heavy-duty operation needs of large-scale equipment[4].
-
Enhanced high-precision end face distribution structure with automatic wear compensation function, optimized internal flow channel design, effectively reducing internal hydraulic loss, the volumetric efficiency can reach 86%-93%, and the total efficiency is higher than the industry average, ensuring ultra-smooth operation at low speed and long-term stable operation under heavy load.
-
High-strength reinforced double-row tapered roller bearings on the output shaft, adopting precision machining, heat treatment and anti-corrosion technology, which can bear larger static and dynamic radial loads than the BM5 series, with strong impact resistance (up to 150% of the rated load), greatly extending the service life of the motor[5].
-
Integrated intelligent monitoring and protection function, optional built-in pressure and temperature sensors, real-time monitoring of motor operation status, timely early warning of overload, overheating and other faults, reducing maintenance costs and improving equipment operation safety[5].
-
Excellent low-pressure start performance and large starting torque (T启=(2.2~3.2) T额), which can realize stable start and continuous operation under low oil pressure and heavy load conditions, with fast response speed and strong adaptability to complex working conditions.
-
Flexible compatibility and wide adaptability, compatible with the mounting flanges, output shafts and oil port types of the BM5 series, supporting customized design of pressure, torque and control mode according to user needs, easy to replace and maintain, and interchangeable with mainstream high-performance hydraulic motor models.
Performance Characteristics
The BM6 series hydraulic motors are high-performance heavy-duty end face distribution orbital geroler hydraulic motors, developed for high-demand low-speed, heavy-duty operation scenarios in industrial and mining fields. As an upgraded version of the BM series, it integrates advanced hydraulic technology and intelligent protection design, adopting internal curve gear meshing principle to ensure efficient and stable power transmission. The displacement ranges from 100.8 cm³/rev to 1300.8 cm³/rev, covering a wide range of torque (260-3300 N·m) and speed requirements (5-820 rpm), and the maximum intermittent pressure can reach 22.0 MPa. The motor features high efficiency, high torque, strong load-bearing capacity, low noise, long service life and intelligent protection, and the total efficiency (actual output power and actual input power ratio) meets the high-standard industrial requirements, making it an ideal choice for high-performance heavy-duty applications that need high pressure and stable operation.
Application Areas
BM6 series hydraulic motors, as the high-performance upgraded version of the BM series, are widely used in various industries requiring high pressure, large torque and stable operation due to their excellent performance, including:
-
Mining machinery: Large coal shearers, roadheaders, mine hoists, crushers and other equipment, adapting to the harsh and heavy-load working conditions of mining sites, with strong impact resistance and long service life[5].
-
Construction machinery: Large hydraulic excavators, heavy-duty rollers, large cement mixers, tower cranes and other equipment, adapting to large-scale construction projects that require high-pressure and heavy-duty operation.
-
Industrial equipment: Large winding machines, high-pressure vulcanizing machines, large injection molding machine preplasticizing screw drives, heavy-duty conveyors, suitable for high-efficiency and heavy-duty industrial production scenarios[4].
-
Marine equipment: Large ship anchor winches, marine cranes, offshore operation platforms and other equipment, with excellent corrosion resistance and load-bearing performance, adapting to the complex marine working environment.
-
