AIR MOTOR (PNEUMATIC MOTOR)

.
Motor adalah penggerak yang umum dan banyak digunakan adalah menggunakan tenaga listrik dan sering disebut dengan elektro motor. Pada sebagian aplikasi elektro motor dianggap tidak dapat mewakili mungkin dikarenakan aplikasi yang khusus seperti karena power dan RPM yang dihasilkan susah diseting atau mungkin karena aplikasi yang menuntut dilarang adanya aliran listrik dan mungkin karena ambient temperatur
yang sangat ekstrim diatas 60 derajat celcius. Karena itu pemakaian motor yang cocok untuk hal ini adalah air motor atau sering disebut dengan pneumatic motor. Seperti halnya elektro motor variabel yang digunakan dalam menentukan model dari air motor ini adalah power ( KW atau HP) serta RPM. sementara untuk mounting juga ada yang foot mounting atau flange mounting.
Dan untuk aplikasi tercouple ke gear dinamakan Air gear motor dan pemilihan dari model harus di informasikan rationya. Yang terpenting pada penggunaan air motor adalah suplai compress air yang harus stabil dan biasanya konsumsi dari compress air ini tergantung besar kecilnya model yang digunakan (HP atau KW ), air motor cukup sederhana sekali cara kerjanya dan kebanyakan terdiri dari 2 macam type yaitu type piston  air motor dan vane air motor, walaupun ada juga yang gear.
Mengenai harga air motor ini jauh lebih mahal dibandingkan dengan  elektro motor, namun kharakteristik yang unggul dari air motor karena sifatnya explosion proof, sehingga aman dari ledakan dan kebakaran, sehingga banyak sekali air motor digunakan untuk mixer pada industri cat yang solvent base.
Hanya saja dalam mengatur besarnya tenaga serta kecepatan putar  dari pneumatic motor dapat diatur dengan mudah dan untuk mengoprasikan cukup dengan membuka dan menutup valve serta untuk besarnya tenaga/tourque pneumatic motor yang dihasilkan cukup dengan setting regulator serta kecepatan putar ( revolotion per minute ) dapat dilakukan dengan setting speed control.
Air motor dalam segi maintennace cukup simple dan bisa dikatakan free maintenance, asalkan kualitas udara yang digunakan memenuhi standart atau telah melewati air treatment dengan benar.
Dari segi harga pnumatic motor atau air gear motor tentunya untuk brand dari USA dan Eropa sangat mahal sekali. Brand yang beredar di pasaran adlah PSI ( neumatic system Inc), Gast, Huco Dynatork, Globe, Atlas copco, Ingersoll Rand, Mannesmann Demag, Deprag Inc.
Jika Ingin harga air motor yang lebih ekonomis bisa menggunakan produk dari China , Taiwan atau Korea dan mungkin Dari Jepang, Air motor Harganya bisa agak murah namun sedikit sekali. Seperti Tonson air motor yang mempunyai variasi aplikasi begitu luas atau lainnya
Dalam menentukan model dan type dari air motor ataupun air gear motor tidak ada bedanya dengan menentukan type dan model dari ectro motor atau electri gear motor yarng digunakan yaitu tenaga /power yang dinginkan dengan standar satuan KW atau HP, selanjutnya adalah jenis dari mounting air motor apakah foot mounting atau flange mounting hal ini tergantung pada aplikasi yang digunakan. Begitu juga untuk Pneumatic gearmotor maka perlu ditambahkan Ratio yang dinginkan.
Secara umum Air motor yang ada di pasaran sesuai standart variant nya tidak terlalu banyak dari segi power yang beredar dipasaran adalah : Power : 0.45 HP , 0.93 HP, 1.7 HP, 4 HP, 5.25 HP, 9.5 HP, dan 2.5 HP
Ratio untuk Air Gear Motor : 15:1, 10:1, 20:1, 40:1, 60:1,

Pneumatic Gearmotor
Known industry wide for their rugged construction and reliability, Gast Air Motors and air powered Gearmotors are available in both lubricated and oilless models.
These air motors and gearmotors are used in many industrial applications, from mixing equipment to running pump drives.
  • Self-sealing vanes take up their own wear, ensuring consistent output for thousands of hours of use
  • Variable speed capabilities allow flexibility and versatility in any number of applications 
  • Cool-running operation means air motors can be used in ambient temperatures of up to 250° F (120° C) 
  • Non-electrical operation reduces the possibility of explosion from igniting flammable gases
Pictured: typical rightangle, worm gear reducer.
A. Bearings
Ball bearings used on input shaft; tapered roller bearings used on output shaft.
B. Case
Fine close-grain cast iron; crankcase sealed; duplex-
milled for parallelism of mounting surfaces.
C. Worm
8620 alloy steel thread rolled to give uninterrupted grain pattern;  carburized and hardened after rolling; high- burnish contact surface from rolling reduces friction coefficient for less heat generation, lower power losses. In large sizes, worms are cut, hardened, and ground to a good micro-finish, providing the ultimate in efficiency and torque capacity.
D. Worm Gear
Forged bronze; geometry and high helix angle give maximum beam strength, high efficiency.
E. Cap Screw
High-strength fasteners with corresponding torque specifications prevent loosening or breaking.
F. Seals
Double-dipped and spring-loaded for leak proofing; tested to ensure compatibility with lubricant.

More reasons why you should switch from electricity to air.
If you compare Gast Air-Powered Gearmotors with any electric-powered  Gearmotor, there’s really no comparison. Here’s why:
  • More horsepower.
    • Size for size, weight for weight, you can’t beat a Gast Gearmotor. A typical rotary vane air motor – the type used in gearmotors – developing 21 /2 hp (1,9 kW) at 1800 rpm and 90 psi (6,2 bar), weighs just 17 pounds (7,7 kg). A comparable electric motor may be two or three times heavier.
  • More speed control.
    • You can’t get more precise turning power than with a Gast Gearmotor. In applications where you need variable speed – like bolt tensioning equipment or rock drilling rigs – one-speed electric motors just won’t fit the bill. Precise lifting, lowering, or turning is simple with Gast Gearmotors.
  • More flexibility.
    • More than most standard electric-powered gear reducers can provide. Gast Gearmotors give you infinitely variable turning power from 73 to 5200 lb. in. (8 to 587 Nm) of torque. And Gast Gearmotors are instantly reversible through easy valving in the air line.
  • More configurations.
    • That makes it easier for our product to work in your product. Our gearmotors are available in four mounting configurations.
  • More life.
    • Unlike electric-powered gearmotors, there’s no chance of burnout with a Gast Gearmotor. They can be stalled indefinitely with no heat buildup. They’re nonelectrical sparking, too, which makes them ideal for use in potentially explosive environments – places where you couldn’t even consider electricity
