Air Motors
The motor to be used should be selected by starting with the torque
needed at a specific shaft speed. In other words, to choose the
right motor, you have to know the required speed and torque. Since
maximum power is reached at half the motor’s free speed, the motor
should be chosen so that the oprating point is as close as possible to
the maximum power of the motor.
The design principle of the motor means that higher torque is
generated when it is braked, which tends to increase the speed, etc.
This means that the motor has a kind of speed self-regulation function
built in.
Use the above graph to choose the correct motor size. The graph
contains the points for the maximum torque of each motor at maximum
output. Add your operating point to the graph, then select a marked
point above and to the right of your point.
Then use the correct working diagram of the chosen motor to get
more detailed technical data. Always select a motor whose requisite
technical data are in the shaded area. Also use the correction diagram
to find out what operation with different supply pressures would mean
for the motor.
Tip: Select a motor which is slightly too fast and powerful, then
regulate its speed and torque with a pressure regulator and/or throttle
to achieve the optimum working point.
