About hydraulic motors
Radial piston hydraulic motor Poclain MG21 is a hydraulic motor converting fluid pressure into rotation. We supply gerotor, axial piston and radial piston motors from Danfoss, Poclain, M+S, SAI, White Drive and Eaton.
Motor types
| Type | Characteristic | Application |
|---|---|---|
| Gerotor (orbital) | Compact, high torque at low speed | Traction drives, winches, augers |
| Axial piston | High pressure and efficiency | Mobile machinery, closed circuits |
| Radial piston | Very high torque | Heavy machinery, drum drives |
What to consider when selecting
- Torque and speed — define required torque and operating rpm.
- Displacement — determines speed and torque at a given flow.
- Shaft and flange type — splined, keyed, tapered; SAE standard.
- Brake — traction and lifting drives often require an integrated brake.
Send the marking or a photo of the nameplate — we will match a genuine part or a compatible alternative with verified mounting dimensions.
Frequently asked questions
How does a gerotor motor differ from an axial piston motor?
Gerotor motors are simpler and cheaper and work well at low speed with high torque. Axial piston motors withstand higher pressure and offer better efficiency, but cost more.
Why does the motor overheat?
Most often due to internal leakage, a blocked drain line or a wrongly set valve. Check the drain line and circuit pressure.
Can a motor be used as a pump?
Many motors are reversible in principle, but not all are rated for continuous pump duty. Check the specific series.
