Choosing an industrial motor is not just about matching horsepower. If you bring home a three-phase motor when your compressor needs single-phase, it won't run. The decision starts with voltage, phase, and mounting. These two new motors sit at opposite ends of that decision. One is a WEG W22 TEFC motor priced at $279.96. The other is a single-phase air compressor motor priced at $455.00. The right pick depends on your machine's power supply and workload.
Quick verdict
If your equipment needs a low-horsepower, foot-mounted motor, the WEG 00112ET3H145T is a precise match. If you need a more powerful air compressor motor, choose the OE Quality unit. The price spread runs from $279.96 to $455, so the WEG is the lower-priced option.
At a glance
| Motor | Price | Price position | Voltage | Horsepower | Standout |
|---|---|---|---|---|---|
| WEG 00112ET3H145T 575V 1 Hp W22 | USD 279.96 | 575V | 1 HP | TEFC, IP55, farm/agriculture duty | |
| 1 Piece 5 HP Single Phase 184T | USD 455.00 | 208-230V | 5 HP | ODTF, direct replacement, 2-year warranty |
Where each product wins
Where the WEG wins The WEG brings NEMA Premium Efficiency and bidirectional rotation, and it sits at the lower end of the price spread.
Where the OE Quality wins The OE Quality motor delivers more horsepower with a 2-year manufacturer warranty. For an air compressor job, that combination is the practical fit, and it is the higher-power choice by a wide margin.
WEG 00112ET3H145T 575V 1 HP W22

The WEG is a specialized 1 HP, 575V, three-phase motor in a foot-mounted enclosure. It runs at 1200 rpm with a 6-pole design, and the TEFC enclosure plus IP55 protection makes it suitable for dusty or damp industrial settings. The farm/agriculture duty tag points to continuous work. Its limitation is voltage and horsepower: 575V three-phase is not a standard residential or light-commercial supply, and 1 HP won't drive a large compressor. For a machine that specifically needs this power class, the WEG matches the spec at the lower end of the price range. The premium-efficiency W22 design and bidirectional rotation add usability, but only within that narrow role.
OE Quality Air Compressor Motor

If your compressor calls for a motor in a 184T frame, this unit is the direct-replacement choice. It runs on 208-230V and draws 28.5-27.0 A. The ODTF enclosure works for compressor duty, and the steel frame is part of the package. The 184T frame is the standard frame here, so matching it to the right compressor mounting is straightforward. Its limitation is that it is not a general-purpose three-phase motor: if your supply is three-phase or your load only needs low horsepower, this motor is more than the application can use. But for an air compressor that expects this exact frame and horsepower, it is the straightforward fit.
Final choice by use case
Choose the WEG when your installation is a low-horsepower, foot-mounted job that matches its electrical spec. Choose the OE Quality when you are replacing or building an air compressor that needs this frame and horsepower. Don't choose based on horsepower alone; choose based on what the motor will be connected to. A motor that doesn't match the power supply, frame, and load won't work no matter how attractive the price is. Getting those three things right matters more than the price tag.
