The correct motor design for any application
1st Quarter 2015
Pneumatic systems & components
Deprag ensures the selection of the correct motor design for any application. Pneumatic motors provide the ideal drive for winding processes, with stepless speed regulation attributed to alteration in the amount of air or operating pressure.
Winding drives can be found in many production processes. They wind continuous materials before or after their handling on spirals, rolls, reels or balls. The spectrum of material to be wound ranges from base paper of up to 10 m wide or thin film with a thickness of 6 m, to carbon fibre threads with low elasticity and high durability against tearing. Every material to be wound places different requirements on the winding drive due to their specific features in terms of surface, hardness, tensile strength, cross-section profile or thickness. Reams of paper with a roll diameter of around 2 m for example are wound at a high speed of up to 2000 m/min. Films are a sensitive material which must be wound or unwound very precisely. The winding of metals on the other hand means that large masses are in play which influence the winding process.
Pneumatic motors are safe and robust drive systems providing a drive solution for winding processes. A pneumatic vane motor consists of a rotor which turns inside an offset chamber in the rotor cylinder. The vanes in the rotor are pressed against the wall of the rotor by centrifugal force creating working chambers. Inside these chambers, the sealed compressed air expands and pressure energy is changed into kinetic energy and the rotor turns.

Selection of two-port valves: an open and shut case
SMC Corporation South Africa
Pneumatic systems & components
Little consideration is generally given to two-port valves because they are often perceived as simple devices that only open and close to control downstream fluid supply. Although this is mechanically true, choosing the optimal two-port valve for your application can make a big difference, saving space, weight and energy consumption.
