Baldor 1/4 HP vs 5 HP Air Compressor Motor: Which One Powers Your Workspace?

Deciding between a low-horsepower 1/4 HP three-phase Baldor and a 5 HP single-phase compressor motor? We compare price, specs, and use cases to help you pick.

Last updated Aug 17, 2026

Choosing the right industrial motor for your shop can be a daunting decision when the specs pull in opposite directions. One is a low-horsepower Baldor unit for lighter tasks; the other is a high-horsepower motor built for air-compressor duty. Both are brand new and priced closely, but they serve entirely different jobs. You need to weigh your power supply, the load you're driving, and the physical fit before you commit. Here's how to decide which one matches your setup.

Quick Verdict

If you need a light-duty motor for continuous, steady operation, the Baldor 0962-28 is the practical buy at $395. If you need a motor to drive an air compressor, the compressor motor at $455 is the stronger choice. The $60 difference is a small price for the extra capability, but only if you actually need that capability. Choose based on the machine you're powering, not just the sticker price.

Where Each Motor Wins

  • The Baldor 0962-28 wins for shops that need a low-horsepower motor for machines that run steadily and don't demand high starting torque.
  • The compressor motor wins when you're driving an air compressor and want a direct replacement unit with the muscle to handle heavy cycling.

In short, your decision hinges on the power supply you have, the physical space, and the starting torque your equipment demands.

Product Notes

New Baldor 0962-28 Industrial Electric Motor 1/4HP, 1425 Rpm, 3 PH, 660V

New Baldor 0962-28 Industrial Electric Motor 1/4HP, 1425 Rpm, 3 PH, 660V

This motor is a new Baldor unit with a 1/4 HP rating and 1425 RPM output, designed for three-phase power. It suits small pumps, fans, and other light equipment that run continuously. The reason to choose it is the combination of new condition and a modest output that keeps energy demands low. Because it is three-phase, it is a good fit for industrial settings already wired for that system. The limitation is its small output: it won't handle high-torque starts or heavy loads, and the three-phase requirement can be a problem if your shop isn't wired for it. So if you already have a three-phase line, this Baldor can handle light duties with minimal fuss and no extra converter.

1 Piece 5 HP Single Phase Industrial Air Compressor Electric Motor 184T Frame

This motor is built for air compressor duty, with a 5 HP single-phase output, a 184T frame, and a direct replacement fit. The reason to choose it is the combination of high horsepower and single-phase convenience, which lets you swap out an old compressor motor without rewiring your shop. The 2-year manufacturer warranty adds peace of mind for a motor that will see hard use. The limitation is that it's a specialized unit: the 184T frame and 5 HP rating target specific compressor applications, not every motor mount. Also, because it is built for the higher torque of compressor cycling, it may be overkill for lighter loads.

Final Choice by Use Case

Choose the Baldor for light-duty tasks with modest power needs; choose the compressor motor for heavy air-compressor duty. Your power source and the load you need to drive will settle the debate.
