FAQs

For the environments and duties electric handles badly: wet, dusty and washdown locations, atmospheres where sparks are unacceptable, and applications with frequent stalls — an air motor stalls harmlessly against load and restarts when it clears, with no windings to burn. The trade-off is efficiency and the need for compressed air supply.

As a curve, not a point: air motors deliver maximum torque near stall and maximum speed unloaded, with rated power between. Match the duty's torque requirement at its working speed against the published curve, at your supply pressure — output scales with pressure. The figures are on each product page; Ask Simon can sanity-check a duty.

Simply: throttle the air supply — a valve in the line varies speed smoothly, and pressure regulation trims torque. Reversible motors swap rotation via a control valve. That control simplicity, with no electronics to protect, is part of the appeal in harsh environments.

More than intuition says: consumption at duty is listed per motor, and a motor running all shift draws like several hand tools, so the compressor's free air delivery must cover it with margin — screw compressors suit continuous motor loads. Filtered, lubricated air and managed exhaust complete the installation.

Air Motors

Air motors turn compressed air into rotary drive: the vane motors that power mixers, conveyors, winches, pumps and custom machinery wherever electric motors are unwelcome, in wet, dusty, explosive-atmosphere and washdown environments where air drive's simplicity is the safety case. PartsForMachines supplies air motors as part of the air tool and compressed-air range, with the compressors that drive them in the same section.

The engineering appeal is what air motors don't have: no windings to burn out under stall, no sparks, no heat build-up, and no damage from being stalled, reversed or overloaded, an air motor simply stops against the load and restarts when it clears, which is why mixing, tensioning and winching duties suit them so naturally. Selection runs on the published curves: power output, free speed and the torque-speed relationship, since air motors deliver maximum torque near stall, air consumption at duty, operating pressure, shaft and mounting format, with speed controlled simply by throttling supply. Each product page lists the figures, with Compare lining up candidates and Ask Simon answering the matching questions, duty torque and consumption against compressor capacity above all.

Installation discipline mirrors the rest of the section: filtered, lubricated air sized for continuous consumption, since a motor that runs all shift draws more than any hand tool, and exhaust management where noise or atmosphere matters.

Air tools, couplings and the compressor ranges complete the system in the same section. For application-matching on specific duties, contact the team via WhatsApp 07754288583.
