Why Three Phase Over Single Phase
Three phase motors deliver power in a steadier, more continuous way than single phase, which means less vibration and a more efficient motor overall. They also start without the capacitors and centrifugal switches single phase motors rely on, which removes a few common failure points entirely.
How Far the Horsepower Range Goes
Single phase power runs into practical limits around 10 to 15HP, but three phase has no such ceiling here. This catalog covers everything from small fractional horsepower units up into the hundreds of horsepower, which is why most larger pumps, compressors, and industrial equipment run on three phase by default.
Specialized Options Worth Knowing About
Beyond general purpose motors, this collection includes explosion proof units for hazardous locations, IEC metric Globetrotter motors sized to European standards, and dedicated saw arbor motors for woodworking equipment. If your application has specific demands, there's a good chance a purpose built option already exists here rather than needing a custom order.
No Three Phase Power at Your Building?
Plenty of shops and farms only have single phase electrical service even though their equipment calls for three phase. A phase converter lets you run a three phase motor off single phase power without an expensive utility upgrade.
Parts and Repair for These Motors
If a motor here needs a new bearing, shaft seal, or endbell rather than full replacement, we stock those separately. Our electric motor repair and rewinding service is also worth a call before buying new, especially on larger horsepower units.
