Direct drive technology compared to the combined motor/gearbox Combined motor/gearbox Direct drives solution

Many market leaders rely on high-torque motors with an integrated thrust bearing from Baumuller as the drive for their extruder screw. This integrated drive approach provides many advantages for the mechanical engineer with regard extrusion technology requirements. Reduction of operating and energy costs © No gearbox losses © Gearbox maintenance no longer necessary © Close adding of drives possible Your advantage Increased cost-efficiency due to improvement in overall economic and ecological benefits. Improved power density Less installation space required due to high integrated design...

DST motors for injection molding machines Many leading manufacturers of injection molding machines are increasingly replacing their hydraulics with direct drive solutions from Baumüller. Baumüller draw from our extensive experience in your market segment and develop, together with you, systems with very high energy efficiency and productivity. Increased productivity and reduced energy costs No system losses due to hydraulic fluids that are converted into wasted heat No heating of the system, meaning there is no need to use a fan motor for temperature control Your advantage Lower energy...

DST motors for printing machines Baumüller was the first system manufacturer in the printing machine sector to perform pioneering work with direct drive technology. In the past, it was more common to drive synchronized rotating cylinders using positive coupling via hard gearing. Increasingly more manufacturers are now relying on direct drive technology with electronic synchronization from Baumüller and are profiting from the advantages. Increased precision Improved control and positioning precision as well as load stiffness because gearbox and gear connections are no longer required....
