240 Volt Single-Phase Electric Motors
240 volt electric motors are designed for applications requiring more power than 120 V circuits can supply, yet where three-phase power isn’t available.
They deliver reliable torque and lower amperage draw, making them ideal for pumps, compressors, conveyors, and fixed machinery in commercial and light-industrial settings.
Built to NEMA Premium® efficiency standards, our 240 V single-phase motors are available in both Open Drip Proof (ODP) and Totally Enclosed Fan Cooled (TEFC) configurations, covering a wide range of horsepower, RPM, and mounting options.

When to Choose a 240 V Motor
Upgrading from 120 V Handles higher HP with reduced current draw.
Commercial / Industrial Facilities Runs larger pumps, blowers, and conveyors efficiently.
Rural Sites with Limited Three-Phase Operates on split-phase 240 V service.
Equipment Retrofits Standard frame sizes simplify swap-outs.
240 V motors are the most common single-phase power solution for small-to-medium machinery operating up to 5 HP.
Enclosure Options
Mounting Styles
Foot Mount Base-mounted for horizontal equipment.
C-Face Mount Flange coupling for pumps & gearboxes.
Rigid Base Compact OEM installations.
Performance and Efficiency
Because 240 V draws half the amperage of 120 V motors, these units operate cooler and with higher efficiency.
All models feature balanced rotors, sealed bearings, and thermal overload protection for continuous-duty cycles.
Typical Applications
Air compressors and vacuum pumps
Agricultural equipment and irrigation systems
Industrial fans and blowers
Conveyors and material-handling machinery
Mixers and process equipment
