Sauer-Danfoss Series 90M — hydraulic motor
Sauer-Danfoss Series 90M is a line of swashplate axial piston hydraulic motors with fixed displacement from 55 to 130 cm³ for closed-circuit hydrostatic systems. The motors are designed as counterparts to the Series 90R/90L pumps and together form a complete hydrostatic transmission. The design is unified with the Series 90 pump line, simplifying maintenance and spare parts selection in field conditions.
Series 90M models
The series includes motors with displacements from 55 to 130 cm³.
All series are available in the Sauer-Danfoss hydraulics section.
Advantages Series 90M
- Five frame sizes from 55 to 180 cm³ allow precise selection of the motor for the required torque and speed
- Parts unification with Series 90R/90L pumps reduces the number of unique components in the repair kit and simplifies staff training
- Compact high-power-density design provides minimal installation dimensions while delivering substantial torque output
- Compatibility with PLUS+1 control systems enables implementation of complex transmission control algorithms
Applications Sauer-Danfoss Series 90M
Sauer-Danfoss Series 90M hydraulic motors are used in the hydrostatic transmissions of grain and forage harvesters from John Deere, Claas, Fendt, and New Holland as drive motors for traction and working attachments. In road construction equipment the series is used in asphalt pavers, road rollers, and trenchers from Hamm, Vögele, and Dynapac.
Parts and repair Series 90M
Quality spare parts are available for the Sauer-Danfoss Series 90M: cylinder blocks, shafts, pistons with slippers, valve plates, slipper retainer plates, seals, and repair kits. Due to parts unification with the Series 90 pumps, a number of components are interchangeable, reducing lead times.
Aspect Plus provides professional repair of Sauer-Danfoss Series 90M hydraulic motors: fault diagnosis, replacement of worn components, and final bench testing with confirmation that parameters have been restored to factory specifications.
