PSI Automation specializes in producing quality air motors that are designed to meet your customized applications. We sell bidirectional and unidirectional motors ranging from 1/4 hp to as much as 70 hp.
PSI’s air motors produce rotational power developed at an output shaft when compressed air is supplied to an inlet port. The objective of an air motor is to produce enough power to overcome a specified torque level and operate at the desired rpm range. The amount of torque a PSI motor can produce is determined by its integrated gearing. PSI uses heavy-duty spur gears for simplicity but offers planetary gearing on some models. Variable rpm and power are attained by simply throttling inlet air. PSI air motor models are designed to run slower with higher torque loads, and faster with lower torque loads. This characteristic is a major advantage in many applications. Matching the motor’s speed range with its available torque allows for consistently reliable high starting and running efficiencies. One important note on model selection should be considered by the purchaser – model selection should be based upon 2/3 of the available supply pressure, or less, as determined for each application.
