EDITO Welcome to the modec world modec vane air motors have been used for more than 30 years as an alternative to traditional electric motors for many heavy duty applications, particularly in chemical, petrochemical and automotive industries. Our team’s technical expertise and business flexibility enable us to develop and provide innovative, robust and powerful air motors as well as specific solutions such as portable valve actuators, tapping machines and nut runners in a short and reliable lead time. Carefully assembled by our experienced fitters in our factory based in Valence, France,...

GENERAL INFORMATION

The Power / Weight output of an air motor is 5 to 6 times higher than that of an electric motor. This makes it ideal for portable applications and / or in cases of space constraints. No spark, no hot spot, hence no risk of fire or explosion in sensitive environments. Air motors deliver a wide speed span that automatically adapts to the required load. All our motors can be ATEX certified on request. Rotation direction, speed and torque are easy to control and adjust, even while motor is running. Remote control is easy to implement. Air motors work in any position. Operating temperature...

HOW DOES IT WORK ? Torque (Nm) An air motor gets its mechanical power from a gas expansion (usually compressed air). Its main characteristics are safety, reliability & compactness. It is easy to use, transport and store. Air motor power first depends on the air (or any other inert gas) supply pressure and flow. For a given supply, there is an inverse relation between speed and torque. Changing the injection point will make the rotor turn the other way around. Thus, changing rotation from clockwise to counterclockwise is possible by simply changing the injection point on the motor. Modec...

4 HOW TO CHOOSE THE RIGHT MOTOR ? A common mistake when choosing an air motor is to focus on its main performances only, without considering the application requirements and the type of work expected from the motor. A TOUCH OF MAGIC IN A BOX Thanks to the integrated gearbox, modec geared air motors deliver speed and torque ranges which are appropriate to different applications’ requirements. And this while keeping a maximum compactness and a close to 100% efficiency. A planetary gearbox is a quite simple mechanism: One or more satellites orbit around the rotor output pinion and drive the...

READY TO CHOOSE THE RIGHT MOTOR ? GET THE RIGHT WORKING RANGE Torque (Nm) To be sure that the motor is adequate, you need not only the right power, but also the right reduction ratio. Simply plot the working point of the application (speed and torque) on the torque/speed curve of each selected motor as shown. If this point is below the torque/speed curve, the motor will be able to do the job. But if the point is above the curve, the motor will not fit your needs. CHOICE OF THE POWER RANGE Once you know the speed and torque required for your application, you can calculate the power required...

5 READY TO CHOOSE THE RIGHT MOTOR ? Reversible motor You’re almost there! Before you start your work, there are just a few steps left. SAFETY FIRST ! Here are some safety rules to follow before using your air motor : 1. Compressor 2. Isolation valve 3. Filter 40µm 4. Pressure regulator 5. Lubrication system 6. 3/2 way valve 7. 5/3 way valve 8. Non reversible motor 9. Reversible motor 10. Exhaust regulator Adequate hearing protection Air motors can be noisy when running and require adequate hearing protection (motor silencer, earplugs or earmuffs). SUPPLY & EXHAUST CONNECTION Adequate masks...

6 AIR MOTORS STORAGE AND MAINTENANCE INGRESS PROTECTION INDEX (IP) With a collected exhaust, our motors can be considered equivalent to IP52. Modec air motors must be stored in a dry environment to avoid any corrosion of mechanical parts. Before storing a motor, introduce 10 drops of modec oil into the supply port and run the motor for a few seconds. Before restarting the motor after a long storage period or before using it for the first time, introduce 10 drops of modec oil into the inlet port. Maintenance must be carried out by skilled technicians trained by modec, in compliance with the...

PRODUCTS DATA SHEETS Product data sheets provide all technical and performance information. We sorted them from the smallest to the highest power range. For each range, you will find first straight motors without and with handle, then right angle drive motors without or with handle. All information included in these data sheets comes from tests performed in our labs. These tests were carried out in very precise conditions and environment, with air pressure, flow, quality and lubrication consistent with our recommendations, and without any option or accessory. However, given the nature of...
