Choosing a 575V industrial motor for a 1 HP application comes down to matching your mounting, speed, and enclosure needs without overcomplicating the decision. If you need a NEMA foot-mounted motor that runs at 1200 RPM and can handle demanding environments, the WEG 00112ET3H145T deserves a close look.
Quick verdict
The WEG 00112ET3H145T is a 1 HP, 575V, 6-pole industrial electric motor from WEG's W22 line. It is a NEMA Premium Efficiency model with a 143/5T frame, foot-mounted F-1 mounting, and a TEFC (Totally Enclosed Fan-Cooled) enclosure rated IP55. It is listed at USD 279.96 and described as new open box. For a straightforward 1 HP, 1200 RPM motor in a NEMA frame, this unit packs the essential features without unnecessary extras.
Who it suits
This motor fits buyers who need a NEMA 143/5T frame, foot-mounted configuration, and a 575V three-phase power supply. The 6-pole design delivers 1200 RPM at 60 Hz, making it suitable for equipment that needs slower shaft speed. The TEFC enclosure with IP55 protection helps resist dust and water jets, so it can be used in workshops, agriculture, or light industrial settings where exposure to debris or moisture is a concern. It is also designed to run in both clockwise and counterclockwise directions, which adds flexibility for different drive arrangements.
What stands out from the listed details
Several attributes make this motor a practical pick. The NEMA Premium Efficiency designation points to energy-conscious operation, which can be a consideration for continuous-duty applications. The dual-direction capability is a nice touch because it means you are not locked into one rotation direction. The F-1 foot-mounted design is the conventional mounting arrangement for many pumps, fans, and conveyors, so it can often be a direct replacement. The included 575V rating is also important: you must have a 575V three-phase supply available, and this motor is specifically built for that voltage.
The price of USD 279.96 positions it as a reasonable entry point for a NEMA framed, TEFC motor with these specifications. The condition is listed as new open box, which may offer some cost savings compared to a fully sealed retail unit, though the exact packing state is not something this article can confirm.
Meaningful trade-offs
There are a few things to keep in mind. The motor is 1 HP, so it is not a heavy-duty workhorse for larger loads. The 1200 RPM speed is relatively slow; if your application needs 1800 or 3600 RPM, this is not the right choice. Also, the 575V requirement is not universal: many industrial facilities run on 230V or 460V, so this motor cannot be used on those systems without a transformer or a different motor. The foot-mounted F-1 configuration may not suit every mounting layout, and the 143/5T frame is a specific NEMA size that may or may not align with your existing equipment. Finally, while the seller notes that it will not ship to Hawaii, Puerto Rico, or Alaska without prior arrangement, that is a logistical detail you would need to handle separately.
