One issue often found with conventional air motors is speed control. The speed can vary with the load and you have no practical control.
There are two options now available which address this issue.
This is a type of centrifugal speed regulation which uses an integrated flywheel with spring loaded weight that controls the flow to the air motor. This is similar to the type that is used on air grinders to prevent overspeed when there is no load on the shaft.
Speed control is maintained within about /- 10%
This option is available in 300, 500, 700 and 1000 Watts.
This consists of a non-contacting speed sensor integrated between the motor and gearbox. The sensor sends a signal to a control module and a proportional valve is used in turn to control the speed of the motor.
This type of speed regulator can also be adjusted to suit different applications.
The electronic speed control system will give much higher resolution and more accurate control than the mechanical system detailed above.
Both of these types of system are normally custom made to suit the application.
