Radial Piston Motor MCR

1.Compact and Lightweight Design

2.High Power and Torque Density

3.Excellent Starting and Low-Speed Performance

4.Modular Construction

5.Low Noise Operation

Detailed description

This hydraulic motor adopts a compact and lightweight overall design through optimized internal structural layout and material optimization. It effectively reduces overall installation space and equipment load, making it highly adaptable to compact machinery and mobile devices with strict space and weight limitations. It delivers outstanding high power and torque density, outputting strong power and torque with a small structural size, greatly improving equipment working efficiency while maintaining a miniaturized structure. The motor achieves excellent starting and low-speed performance with stable pressure and flow control. It features smooth starting response, no jitter or crawling phenomenon, and can operate steadily at ultra-low speeds to meet precise and stable operation requirements. Adopting a mature modular construction, it supports flexible assembly and quick replacement of components, simplifying installation, maintenance and later upgrading. In addition, optimized internal flow channels and precision machining parts effectively reduce fluid turbulence and mechanical friction, realizing low noise operation and providing a quiet and stable working environment for the whole hydraulic system.

Selection and RFQ

This motor series should be selected from the required torque, speed and duty cycle. Confirm displacement, working pressure, case-drain arrangement where applicable, mounting interface and fluid conditions before final selection.

Information to include in your RFQ

  • Required torque and speed at working pressure
  • Preferred displacement or calculated displacement
  • Mounting flange, shaft and port orientation
  • Duty cycle, fluid, temperature and operating environment

Notes on technical data

T= Torque in Nm qV = Inlet flow in L/min qVL = Case drain flow in L/min
-All torques apply to run-in motors (see note p. 4, footnote 7)
-For "half displacement" mode multiply torque- and qV-values by 0.5.
-The torque values at half displacement do not apply to both directions of rotation but only to the preferred direction of rotation marked (see pp. 7-9)
