BM2 series orbital hydraulic motor is a small motor of low speed, high torque, with a stator-rotor package in toothed shape.
Advantage:
1. Small, lightweight , smaller than other orbit motor of same torque
2. Wide speed range, non-grade adjustment of speed, minimum steady speed is 15rpm, easy and convenient to be equipped with, low cost
3. Used in series and in parallel way of a hydraulic system
4. Small rotary inertia, easy to be started, rotate clockwise and counterclockwise, no need stopping rotating when change direction
Main function features:
1. Shaft groove distributes flow, simple and compact structure, high accuracy of flow distributing
2. Stator-rotor in toothed shape, high mechanical efficiency, longer working lifetime under high pressure
3. Touching-ball bearing of coupled-angle, bear higher loading in both radial and axial direction, small friction force, high mechani-cal efficiency.
