Huco Dynatork’s comprehensive new 30-page catalogue highlights the merits of the piston air motor where the application involves harsh duty cycles and hazardous environments. It also contrasts its performance against that of a vane motor, where the air motor’s advantages include far greater energy efficiency and low noise. The seven product groups in the Huco Dynatork range offer maximum torques from 2Nm to 550Nm. They consist of air motors in aluminium, acetal and cast iron, spur gear motors, worm gear motors, planetary gear motors, and electronically controlled pneumatic stepper motors. With neglible leakage, these offer maximum torque at minimum air consumption, plus instant stop-start.
