M+S Hydraulic Motors
Reliability and high torque in low-speed applications
Fluid System distributes M+S Hydraulic (MS Hydraulic), one of Europe’s leading manufacturers in the design and production of LSHT (Low Speed High Torque) orbital motors. These motors convert hydraulic energy into rotary motion with maximum efficiency even at low speeds, offering high torque, robust construction and long operating life.
Thanks to the wide range of Euro versions (metric standards, ISO/DIN flanges and BSPP ports), M+S Hydraulic motors ensure full compatibility with European hydraulic systems and adapt easily to mobile, agricultural, industrial and handling applications.
LSHT Orbital Motors
High performance and versatility for mobile and industrial systems
M+S Hydraulic orbital motors use the gerotor / roll-gerotor principle, in which an internal rotor transmits torque to the output shaft with consistent efficiency and torque available from start-up. Disc-valve and spool-valve versions ensure smooth response and torque continuity, while the range of mechanical configurations – flanges, shafts, side or rear ports – provides maximum integration flexibility.
TECHNICAL FEATURES
Continuous operating pressure up to 200-250 bar, with peaks up to 275-325 bar depending on the series.
Maximum torque up to 260 daNm (MS series) and 229 daNm for MT/MV versions.
Displacements from 8 to 565 cm³/rev, depending on the series.
Operating speeds optimised for LSHT applications, with high torque at low speeds.
Euro standard versions, with metric flanges and BSPP connections.
Available options: integrated brake, speed sensor, drive-wheel variants and compact “short motor” mounting.
Compatible fluids: HLP mineral oils (DIN 51524) or HM oils (ISO 6743/4); optimum viscosity 20-75 mm²/s.
Main applications
M+S Hydraulic orbital motors ensure controlled motion and high torque in applications where continuous power at low speed is required.
- Agricultural and forestry machinery.
- Construction and earthmoving vehicles.
- Conveyors and travel systems.
- Textile, wood-processing and plastics machinery.
- Compact equipment and special vehicles.
