Air Motors

Product catalog summary

Introduction
Air motors are versatile power sources ideal for operations requiring rotational drive. They are advantageous over electric motors due to their compact size, ease of speed and torque control, and resistance to harsh conditions.

Advantages of Air Motors

High power-to-weight ratio: Smaller and lighter than electric motors, suitable for portable applications.
Simple control: Speed and torque can be adjusted by regulating air pressure or flow.
Durability: Can stall without damage and resume operation quickly.
Safety: Explosion-proof and operable in hazardous environments.

Technical Terms

No load speed: Maximum speed at a given air pressure without load.
Maximum power: Achieved at about half the no-load speed for vane type motors.
Dynamic torque: Torque output during operation, increasing linearly from zero to maximum at stall.
Stall torque: Torque when the motor stalls due to load.
Starting torque: Higher than running torque to overcome inertia.
Air consumption: Maximum at no load, decreases with reduced air pressure.

Performance Specifications

Standard air inlet pressure is 6.3 bar, with a 14% power drop for every 10% reduction in pressure.
Non-reversible motors rotate clockwise when viewed from the air inlet end.

General Information

Air motors are components for machines, with safety responsibility on the customer.
Sound levels measured according to EN ISO15744, with nominal values subject to variation.

Selecting an Air Motor

Determine if a single or reversible motor is needed, then consider required speed and torque.
Select a motor with twice the free running speed of the required speed under load.
Use performance graphs to ensure the motor meets specifications.

Series Overview

DM6/DM65 Series: 0.35 hp, non-reversible, max torque 5.9 lbf ft.
2DM6 Series: 0.35 hp, reversible, max torque 5.9 lbf ft.
HM Series: 0.6 hp, non-reversible, max torque 30 lbf ft.
HM55 Series: 0.85 hp, non-reversible, max torque 30 lbf ft.
2HM5 Series: 0.85 hp, reversible, worm drive.

Conclusion
Air motors offer a reliable and efficient solution for various industrial applications, providing flexibility in control and operation in challenging environments.

Rotation non-reversiblemotors rotate in a clockwise direction if the motor is viewed from the air inlet end with the spindle pointing away from you. Performance specifications ֖ are normally shown with an air inlet pressure of 6.3 bar at the air motor, unless otherwise stated. Note that there is approximately a14% drop in power for every 10% reduction in air inlet pressure. > Air consumption measured inthe no-load condition. Air consumption is maximum at no load, and is approximately three quarters of this figure at maximum power. Air consumption reduces as the working air pressure is reduced....
