This belt-driven rodless electric actuator is characterised by the fact that the motor and reducer unit is integral with the carriage, instead of being fitted to one end of the extruded section. This solution is known as s'cantilever. In the typical application the carriage is fixed while the extruded section moves. The SVAK can be used either horizontally or vertically, but the most common use is in vertical applications, which explains why the motor is supplied complete with a brake that causes the axis to remain still even when it is not electrically powered. The SVAK can be applied to the SHAK GANTRY series to obtain an X-Y-Z Cartesian manipulator robot featuring high performance and rigidity. The SVAK uses the universal V-Lock modular system for fixing the carriage to external auxiliaries and the various components to one end of the extruded section. The sides of the extruded section, which is made of anodised aluminium, houses two hardened and ground guides that slide on adjustable wheels that are integral with the carriage. The carriage is moved by a toothed belt, complete with a tensioning system. Guide lubrication nozzles are also provided on the carriage. A BRUSHLESS motor with a toothed belt 1:2 gear speed reducer for the pulleys was also chosen. This design was opted for because it ensures excellent load capacities without sacrificing dynamics and the typical speed of this product. In addition to the standard drive proposed in the catalogue, it is also possible to customise the cylinder by using other motors. The homing position is detected by an inductive proximity sensor included in the supply.
