By certification 
BM5 series of orbital hydraulic motor is a small, low-speed orbit-motor of inner meshing gear.
Advantage：
1.Small,light weight, size is quite smaller than other hydraulic motor of same toque
2.Wide speed range, non-grade adjustment of speed, minimum steady speed is almost 15rpm, easily and conveniently assemble way, low cost
3.Be used in hydraulic system in series or in parallel
4.little inetia of rotary, easily to be started, can rotate clockwise and counterclockwise, don’t have to stop rotating when change direction
Main function features:
1.Disc distributes flow, simple and compact structure, high accuracy of flow distributing
2.The compensate disc of pressure compensation mechanism can automatically fill in the radial gap caused by the frictions between compensate disc and flow-distribution disc ,between flow-distribution disc
