Air motors

Dental turbines usually run at 150,000 to 300,000 RPM's with very little torque.

Dear sir,

kindly check ingersol rand,aro and other pneumatic tool manufacturer.

sankar

Dotco, Aro, Atlas Copco, Master Power, Sioux, Ingersoll-Rand, Air Turbine, Dynabrade

Cleco, Florida Pneumatics. Look under Cooper Tools they produce Dotco, Aro, Ingersoll-Rand and Cleco.

Most Air Motors RPM's 20000 plus

Gast makes air motors at max 6000 RPM.

I am sure I can help you with your application. I have been in the air motor / air tool business for over 40 years and specialize in special application air tools and air motors. Please advise what your application is and the exact requirements you need. I worked as a Sr. Pneumatic Design Engineering consultant for several major brand name airtool companies.

Thanks and good luck, I hope we may be of some help to you..

it is good to know of somebody who has worked for 40 years in air motor field. i also have been racking my brain about air motor for an unusual application. my requirement is for motor of considerable size.

problem: flooding of low lying areas on both sides of a big storm water drain during episodes of heavy rainfall. though the duration of overflow is for short havoc it creates is enormous. the gredient along the drain is not much so much so pump assisted evacuaton of water has to be done.

soluton proposed: place propeller pumps along the water flow direction and connect it to safer areas through high density polythene pipes of dia 10 inches to 20 inches. the length of pipe could be as long as 1 mile. for reasons of safety, electric motor cannot be used. diesel engine drive is unacceptable due to bulk, weight and possibility of stoppage due to many reasons when in proximity to splashing water. air motors driven by compressors placed on bank of the drain is ok. power requirement is equivalent to 5o to 100 HP. Air motor will be hooked up to propeller pump directly or through gear drive. ideal pump speed is about 1000 rpm. is it practicable?

Please contact me directly as I may have a solution for your problem. We work with large industrial special application air motors that develop 80,000 to 100,000 ft.lbs. of torque and large HP. Your application will require a lightweight motor that will run at 100 to 120 psi , produce 50,000 to 80,000 ft. lbs and have a flow cfm of around 65 to 75. What type of compressor do you anticipate using ?? It should be a large industrial type of at least 500 CFM and have a screw type compressor unit. If you have an interest in our working with you to develop an air motor for your application please contact me at ata@stny.rr.com . I have almost 50 years in the air motor and air tool development field and have spent most of my working life as a Sr. Pneumatic Design Engineer consultant to several major air tool companies such as Ingersoll-Rand.

I hope we may be of some help to you..

Why are electric motors not allowed? Safety?

What about the safety of this huge amount of compressed air that needs to be transported over 1 mile.

Does the installation need to be transportable?

The best and reliable solution is electric driven submersible pumps, with a diesel gen-set you can supply them when the normal power fails.

Electricity can be made very reliable and sub water level proof. (IP 68 + water height specification)

thanks for the replies. Can you tell me what kindof air motors are used in Air drills. I believe they must be pretty compact with low speed.

Air motors that are used in drills have a very wide variety of speeds and sizes. It also depends on material being drilled - type of bits - type of motor such as turbine or vane and being run on compressed air or with hydraulics such as oil or water. If you have a specific idea of what you need to accomplish, please e-mail me and I will try to advise and assist you in any way I can. I have designed air drills as small as .75 OD and as large as 8" OD. They have run on air and N2 (pneumatic) as well as oil and water (hydraulic). Excellent question are you looking for a small drill for a special project. I can also assist you with any FEA and CAD 3D models if you have a need.

i think the air motors used in the air drills are pretty low power as looking at the costs which is about 30 or 40$. I am wondering if it would be possible to dismount the air motor alone from the drill.

I could address your air motor better if you could give me some info such as - what speed (rpm) does your application require - air pressure (psi) required - torque (ft.lbs / in.lbs or Nm) - power (hp) required and an idea of what it will drive and/or be used in.. Using an existing air motor out of an air drill or any air tool for that matter is not practical and could be down right dangerous to the user and/or application. The use of air (pneumatic power) is not complicated but.. can be outright dangerous to the person or persons that have no or limited experience using pneumatic powered tools or equipment. I have a lot of experience and even after 45 plus years in the pneumatic fields - I AM VERY CAUTIOUS when I handle and use any air powered anything !!! Most probably I can help you if I have more to go on - I can then make some suggestions or recommendations to you..

Good luck - I hope I may be of some help to you.. ata@stny.rr.com
