Motor purpose and fit
The Dayton 31LH32 is a general-purpose three-phase motor rated at 1.5 HP with a nameplate speed of 3510 RPM. It suits HVAC equipment such as fans, blowers or pumps that require 230/460 V AC supply and continuous duty operation.
Installation practicalities
The unit mounts on a rigid base using a standard 56H frame, so alignment with driven equipment is straightforward for technicians familiar with three-phase wiring. Common issues include incorrect phase rotation causing reverse direction, and the absence of built-in thermal protection meaning external overload devices must be provided.
Voltage and duty limits
The motor operates on 230/460 V at 60/50 Hz with a full-load current of 3.7 A at 230 V and 1.85 A at 460 V. Its 1.15 service factor allows modest overloads, but the 40 °C maximum ambient temperature and open drip-proof enclosure restrict use in hot or wet environments.

Questions about this item
How can I verify the motor is running at the correct speed after installation?
Use a tachometer to confirm the shaft rotates at 3510 RPM under load; the nameplate lists 3510 RPM as the rated speed.
What comes with the motor and what must be sourced separately?
The motor ships with a rigid steel base and a 56H frame; you must supply three-phase 230/460 V power, overload protection, and any coupling or pulley.
Which voltage connection should I use for a 230 V three-phase supply?
Wire the motor for the low-voltage 230 V connection; the nameplate shows 3.7 A full-load amps at 230 V and 1.85 A at 460 V.
