Dayton 36VE91 GP Motor 1 HP 1770 rpm 7/8 in. shaft
Three-phase general-purpose motor delivering 1 HP at 1770 rpm with a 7/8 in. keyed shaft for HVAC equipment
- 1 HP motor drives pumps and fans
- 1770 rpm nameplate speed suits standard HVAC loads
- Dual-voltage 208-230/460 V fits common supplies
- 7/8 in. keyed shaft matches typical couplings
- Open dripproof frame rated for 40 °C ambient
1 HP Three-Phase General Purpose Motor
The Dayton 36VE91 is a 1 HP three-phase general purpose motor rated for 1770 RPM at 60 Hz. It operates on 208-230/460 volt supply with a 7/8 inch keyed shaft and rigid base mounting for horizontal installation.
Replaces Worn ODP Motors in Fixed-Speed Applications
This unit serves as a direct replacement for failed open dripproof motors in pumps, fans or compressors where nameplate RPM and frame size match. The jump is worth it when the existing motor shows bearing noise, insulation breakdown or thermal trips and the driven load does not require variable speed control.
Suits Maintenance Teams Standardising on NEMA
The motor fits facilities running 208-230/460 V three-phase power with ambient temperatures up to 40 °C and a 1.15 service factor. It is not for buyers who need single-phase input, vertical mounting, built-in thermal protection or an inverter-rated design for variable frequency drives.

Questions about this item
What size mounting base does the 182/4 frame motor require?
The motor uses a rigid base mount on an 182/4 frame and must be installed horizontally; verify the base bolt pattern matches your equipment before ordering.
How do I wire the 208-230/460 V three-phase supply to the terminal box?
Connect the three supply leads to the terminal block for either low voltage 208-230 V or high voltage 460 V; the nameplate shows 2.9-2.7/1.3 full-load amps, so size the branch circuit and overload protection accordingly.
When should I plan to re-lubricate or replace the ball bearings?
The motor has ball bearings with no factory relubrication interval published; inspect for noise or vibration annually and replace bearings if roughness or excessive play develops.
