Choosing an industrial motor means matching more than just horsepower. You need to confirm three-phase input, the voltage your facility runs, the RPM range your equipment uses, and the frame size that physically fits the mount. The four motors here span 3 to 15 HP at 1725-1800 RPM and are listed from USD 332.63 to USD 1,500.00, so the real decision is how much power you need and how much frame size matters.
Quick Take
- For 15 HP, 254T-frame duty: the Dayton 15 HP TEFC motor at USD 1,500.00 is the only motor in this comparison at that power level.
- For a 5 HP, 460V general-purpose motor: the Baldor 5F604-1709 at USD 450.00 is the new, US-made design B option.
- For 3 HP: the 182T-frame TEFC motor at USD 363.99 gives you 230/460V input in a compact frame.
- For 5 HP with a 184T frame and severe-duty build: the 5 HP TEFC motor at USD 332.63 is the lowest-priced motor in the group.

Product Notes
Dayton 15 HP Industrial Electric Motor 230/460V 3-Phase TEFC 1770 RPM Frame 254T
The reason to choose the Dayton is simple: it's the only 15 HP three-phase motor in this comparison. It runs at 1770 RPM on 230/460V, uses a 254T frame, a TEFC enclosure, F-class insulation, and is described with a 1.15 service factor. It comes as a new open-box unit that has not been installed or used, though it may have minor cosmetic marks from storage and handling. The limitation is price: at USD 1,500.00, it's the costliest motor here, so it makes sense only when your load really needs 15 HP.
Baldor 5F604-1709 Industrial Electric Motor 3-Phase 35F604-1709 1725RPM 60HZ
The Baldor is a new 5 HP motor designed for 460V three-phase power and 60 Hz operation. It carries a NEMA Design B general-purpose rating, has a keyed and reversible shaft, and is made in the United States. At USD 450.00, it's the mid-price 5 HP option and the one you'd pick if you want a 1725 RPM motor with a Baldor model number. Its limitation is that it's rated at 460V, while the other 3 HP and 5 HP motors here show 230/460V operation, so it's the 460V-focused choice.
3 HP 3 Phase Electric Motor 1800 RPM 182T Frame 230/460V TEFC Premium Efficiency
This 3 HP motor gives you the compact 182T frame size with 230/460V dual-voltage input, so it's the natural fit for a lighter three-phase load. It's listed at USD 363.99, it runs at 1800 RPM base speed, and the attributes call out premium efficiency, Class F insulation, NEMA Design B, and an IP55 TEFC enclosure with a 1.25 service factor. The limitation is output: at 3 HP, it's the least powerful motor in the group, so it's only a match for equipment that doesn't need more than 3 HP.
5 HP 3 Phase Electric Motor 1800 RPM 184T Frame TEFC 230/460 Volt Severe Duty AC
The 5 HP, 184T-frame TEFC motor is the lowest-priced option in the comparison at USD 332.63. It's rated for 50/60 Hz, with a base RPM of 1800, a full-load speed of 1755, Class F insulation, IP55 enclosure, and a 1.15 service factor, and it's built as a severe-duty unit. That makes it a strong candidate when you need 5 HP but want to keep the purchase price down. The limitation is its 184T frame: if your existing motor mount is sized for a 182T frame, this one will not be a direct frame swap.
Final Recommendation by Use Case
Choose the Dayton 15 HP TEFC motor when your pump, compressor, or conveyor needs 15 HP and a 254T frame. Choose the Baldor 5F604-1709 when you want a new US-made 5 HP motor at 460V with a design B rating. Choose the 3 HP 182T-frame motor for lighter, compact three-phase duty at USD 363.99. And choose the 5 HP 184T-frame severe-duty motor when you need 5 HP, TEFC protection, and the lowest listed price at USD 332.63.
