GLOBE RM012 compact piston motor Low speed, high torque Oil free, silicone free GLOBE has developed a new compact piston motor with the next benefits: • 12 pistons for very low speeds and smooth running improved design pistons for longer life time silicone free so very useful in mixing applications available with front flange which incorporates an extra bearing special version for food and chemical industry ATEX approved Operating principle front cross sectional view in the compact piston air motor displayed are 7 pistons, the RM012 has 12 pistons The radial piston principle presented here operates without rod or crank shaft. The radially arranged driving pistons travel along a curve and are inevitably controlled by the centre. The static control shaft supplies the driving pistons with the necessary air. Air supply and release openings along the static driving shaft are periodically opened and closed by the rotating shaft to pressurise or release the pistons in an appropriate sequence.

GLOBE RM012 compact piston motor Low speed, high torque Oil free, silicone free Six of the twelve driving pistons are actively contributing to the torque at any moment. Once reaching the highest point on the curve, the air driving the piston is released by the control unit and the piston is forced into its lowermost position. This operating principle is equivalent with the one of a simple cylinder. The compact piston air motor’s high torque is due to the power transmission of the pistons along the large external diameter of the curve. The friction connected with the travel along the curve...
