When you're choosing an industrial motor, the first decision comes down to horsepower and voltage: do you need a high-output single-phase motor for air compressor duty, or a lower-horsepower three-phase motor for a farm or light industrial line? Here we're comparing two 60 Hz TEFC motors at clearly different price levels: the 5HP 1750RPM Air Compressor Electric Motor 184T Single Phase TEFC 208-230V and the WEG 00112ET3H145T 575V 1 Hp W22 NEMA Foot-Mounted Industrial Electric Motor.
Quick verdict
If your job is running single- or two-stage air compressors on a 208-230V single-phase feed, the 5HP 1750RPM Air Compressor Electric Motor is the motor to buy. It delivers 5 HP at 1,750 RPM in a totally enclosed fan-cooled package with IP54 protection. If your facility runs on 575V three-phase and you need a compact foot-mounted motor for farm or agriculture duty, the WEG 00112ET3H145T fits that role with IP55 protection.

Where each motor wins
The 5HP 1750RPM Air Compressor Electric Motor wins when you need maximum output: 5 HP, 1,750 RPM, and single-phase operation for compressor work. Its 184T frame and rolled steel shell are suited to continuous duty, and the IP54 rating means it can handle limited dust and water spray in a compressor setting.
The WEG wins when your supply is 575V three-phase and you need a lighter-duty motor with a foot-mounted frame. The W22 design, 1,200 RPM output, and both CW and CCW rotation make it a flexible fit for agricultural equipment, and its IP55 ingress protection is a step above the 5HP motor's IP54 rating.
Product notes
5HP 1750RPM Air Compressor Electric Motor 184T
This is the higher-priced motor of the pair at $449.99, and it brings the most power: 5 HP at 1,750 RPM in a single-phase TEFC package. The product is described for single-stage and two-stage air compressors, so it's built for steady torque through continuous compression cycles. The 184T frame and rolled steel shell are useful details for a compressor environment. Its main limitation is voltage: it runs on 208-230V single-phase, so a facility with 575V three-phase service can't use it as a direct replacement. If your compressor calls for a 5 HP single-phase motor at 1,750 RPM, this is the one to choose.
WEG 00112ET3H145T 1 HP 575V Foot-Mounted Motor
The WEG is the lower-priced option at $279.96, and it's made for farm/agriculture duty with a foot-mounted NEMA frame. It produces 1 HP at 1,200 RPM from a 575V three-phase supply and is fully enclosed with IP55 protection, which is higher than the 5HP contender's IP54 rating. The W22 NEMA Premium Efficiency design, plus CW and CCW rotation, are listed advantages of this foot-mounted unit. The clear limitation is horsepower: this motor won't deliver the same air-moving output as a 5HP compressor motor, so it's only the right pick if 1 HP is enough for the job. For a 575V three-phase line, it's a sensible lower-priced choice.
Final choice by use case
Choose the 5HP 1750RPM Air Compressor Electric Motor 184T if you need 5 HP at 1,750 RPM with single-phase 208-230V power for single- or two-stage air compressors. It's the highest-output motor here and the only one matched to compressor duty.
Choose the WEG 00112ET3H145T 575V 1 Hp W22 NEMA Foot-Mounted Industrial Electric Motor if you need a compact 1 HP, 1,200 RPM motor on a 575V three-phase line with farm/agriculture duty. It offers IP55 protection and a foot-mounted frame for that type of installation.
