Wherever high forces have to be applied in mobile applications, hydraulic systems are used. Typical examples are agricultural and construction machinery such as tractors, combine harvesters, excavators, loaders and forklift trucks. As a long-standing supplier to leading companies like John Deere, Sonceboz has extensive experience of stepping motor technology for mobile hydraulic uses.
 
For the adjustment of mobile hydraulic components such as multi-way valves, electro-hydraulic pre-controls with proportional magnets are used in most cases nowadays. By adopting mechatronic systems with stepping motors and integrated electronics with a CAN bus instead of classic servo-elements, a number of significant advantages are achieved:

In this application a mechatronic system from Sonceboz is being applied to a hydraulic situation. A hybrid stepping motor with gearbox is built into an enclosure along with the control electronics. The control electronics have a CAN bus interface.
 
Typical examples include agricultural and construction machinery such as tractors, combined harvesters, excavators, loaders or forklift trucks. By their nature, these machines are exposed to special strains such as extreme load changes, impacts and vibrations. These influences act on the built-in hydraulic systems and require considerable expenditure on regulating technology for stabilization purposes. The use of mechatronic stepping motor drives enables some of these difficulties to be resolved elegantly.
