Need compact piston air motors for their high starting torque? MODEC air motors have this too – but without piston motors’ disadvantages.

Not all compact air motors are equal, and air motors manufacturers will be quick to inform you of the benefits of their particular design without necessarily comparing it to different types of motor. As a general comparison though, piston-type motors are larger, heavier, are relatively complex, more costly, and only achieve relatively low RPM while having the advantages of high starting torque and low air consumption per unit time. Vane-type motors can be smaller, lighter, simpler, and can achieve high RPM while often having low starting torque and higher air consumption per unit time. These differences are important to consider when implementing a compact air motor system.

But is it necessary to accept the trade-off on price, size, weight and complexity in order to enjoy the benefits of compact piston air motors? We assert that it isn't. MODEC, a leading geared air motors manufacturer, effectively achieves the torque advantages of piston motors but retains vane air motor prices, weight, size, simplicity, and high RPM. This is due to a cluster of technologies that allow their motors to achieve high torque. The other supposed advantage - efficient air consumption - is then addressed by MODEC's systemic approach to workplace component design, enabling energy savings of an order comparable or superior to those of compact piston air motors.

High torque, often not achievable by vane-type designs, is made possible with MODEC's compact geared air motors. A planetary gearing system is the central innovation that drives this solution, benefitting from the high power density, small volume, and pure torsional reactions of such systems. This gearing offers several reduction levels to suit any given application - while still offering the relatively high RPM a vane motor provides. Operating in conjunction with planetary gearing, a torque limitation system prevents output shaft breakage, and a coupling ring can be employed for especially high torque requirements while maintaining the size advantage of these compact geared air motors.

It's well known that compact vane air motors offer a price advantage over piston types, but their higher air consumption can often prove more expensive overall. For this reason, MODEC's systems approach is perhaps their most valuable innovation. Apart from the obvious low maintenance and repair costs, ATEX motor safety certification, versatility, and ease of use, the efficiency advantage of MODEC's motors inheres in the fact that air pressure must be maintained whether components use it or not, thus energy expenditure is constant even when motors are not running. For this reason MODEC chooses the multiple advantages of compact vane air motors: high air consumption per component frequently does not impact overall energy usage.
