Hydraulic motor with integrated Brake is the MT/B Brake Motor. These motors have disc valve. The distributor valve has been separated from the output shaft and is driven by short cardan shaft. A balance plate counterbalances the hydraulic forces around the distributor valve. It gives the motor high efficiency even at high pressures and good starting characterstics. The Gerotor set have teeth fitted with rollers. The rollers reduce local stress and the tangential reaction forces on the rotor reducing friction to a minimum. This gives long operating life and better efficiency even at continuous high pressures.
Options
- Fully integrated friction disc brake.
- Side ports.
- Shafts: Straight, Splined or Tapered.
- Ports: BSPP
