Choosing a 15 HP industrial motor isn't just about horsepower. You have to match voltage and phase to your facility's power supply, confirm the frame size lines up with your driven equipment, and decide whether the enclosure protects against dust, dirt, and other shop hazards. The Dayton 15 HP Industrial Electric Motor (230/460V, 3-Phase, TEFC, 1770 RPM, Frame 254T) aims to cover many of those bases, and the listing shows a $1,500 price for a new open-box unit. Here's a close look at what that gets you.
Quick verdict
This motor is a solid fit if your application already runs on three-phase power and you need a foot-mounted TEFC unit in a 254T frame. The open-box condition may bring minor cosmetic marks, but the motor itself is described as new and never installed. For facilities running pumps, compressors, conveyors, fans, or blowers, the specs align with typical continuous-duty needs.
Who it's for
Industrial maintenance teams and equipment builders that have 230/460V three-phase available will find the Dayton 15 HP easiest to work with. The 1770 RPM speed and 254T frame make it a direct replacement candidate for many industrial blowers, compressors, and conveyors. The foot-mounted design simplifies alignment with pulley or coupling drives when the existing base is set up for a footed motor. Because it is TEFC, the motor is better equipped for environments with airborne dust and particles than an open drip-proof design might be.
What stands out
Looking at the listed details, the service factor is 1.0, which means the motor is designed to handle its stated 15 HP output under continuous duty without extra overload capacity. Insulation Class F (rated for max 311°F) offers a thermal margin that supports demanding cycles. The dual-voltage rating (230/460V) gives facilities some flexibility when connecting to different three-phase systems, and the full-load amps of 37.5A at 230V or 18.8A at 460V help when sizing overload protection. The listed $1,500 price is the starting point to weigh against your budget for a motor with these specifications.
Trade-offs to weigh
The most obvious trade-off is the open-box condition. The seller describes it as new and never installed, but says it may have minor cosmetic marks from storage and handling. That doesn't affect function as described, but it does mean the motor won't be as shelf-pretty as a factory-sealed unit. Also, because this is a three-phase motor, it won't run on single-phase residential power. If your shop only has single-phase service, this isn't the right motor regardless of price. Make sure your application is built around a 254T frame motor, since that's what this unit offers.
Bottom line
If the specs match what your equipment needs-15 HP, 3-phase, 1770 RPM, 254T frame, TEFC-the Dayton motor is a straightforward choice at its listed $1,500 price. The open-box packaging is the main caveat, but the motor itself is described as new and never used. For a facility with the right power and mounting setup, this could be a reliable workhorse.
Dayton 15 HP Industrial Electric Motor 230/460V 3-Phase TEFC 1770 RPM Frame 254T
This is the motor under review. It comes new in open-box condition with potential minor cosmetic marks from storage, and its 230/460V three-phase operation, TEFC enclosure, and 1770 RPM output make it best suited for industrial pumps, compressors, conveyors, fans, and blowers. The primary limitation to weigh is the open-box condition, along with the requirement for a three-phase power supply.
