CA210 High-Efficiency Motor

Working principle

Radial pistons push against a fixed cam ring. Hydraulic oil enters cylinder block, pistons generate radial force, force drives cylinder block + hollow output shaft rotate.

Model code example

1. CA210 = frame size

2. 210 = variant (13200 cc/rev, 210 N·m/bar)

3. SA0N00: shaft type, mounting, brake option

4. 02: rotation direction

5. 00: design revision

Key features

1. Hollow through shaft: Drum cable can pass through shaft centre, ideal for marine winch / windlass direct drive, eliminate gearbox

2. High shock load tolerance, robust construction for heavy pulsating loads

3. Very good low-speed stability, smooth rotation at near-zero rpm

4. Modular rear cover: can add MDA holding brake if needed

5. Compact envelope compared to older Hägglunds MB / Marathon motors

Mounting & Commissioning points

1. Torque arm must be fitted correctly, no rigid coupling that transfers reaction torque to shaft

2. Case drain line must run continuously downhill to tank, avoid high loops. High case pressure will damage shaft seals

3. Before commissioning: fill motor housing with hydraulic oil, vent air

4. Rotation direction defined at order, check port connection matches rotation

Typical applications

• Marine: anchor windlass, deck winch, dredger cutter head drive

• Mining: heavy feeders, conveyors, shredders

• Heavy industry: rotary kiln, large mixer, TBM auxiliary rotary drive

  
  

Common faults for standalone CA210

1. Leakage: shaft seal failure, usually from excessive case backpressure

2. Low torque: internal piston/cam wear, insufficient supply pressure

3. Vibration & noise: loose torque arm, air entrained in oil, damaged cam ring or rollers

4. Overheating: insufficient flow for cooling, internal wear causing high volumetric losses
