Piston Air Motors

RADIAL PISTON MOTOR

Piston Air Motors develop high torque and are well-balanced. They have three, four, or fives, providing for even torque at all speeds and smooth delivery of power with each revolution in either direction of rotation.

This type of motor operates at a much slower speed than does a vane-type motor because of the weight resulting from its reciprocating parts. Free speed is usually 3000 rpm or less. Maximum horsepower is usually developed at 1000 rpm or less. The smooth, overlapping power flow and accurate balancing of radial piston motors make them vibration-less at all speeds, a feature especially noticeable at lower speeds where maximum torque is developed.
