- 84 % nominal efficiency reduces operating cost
- 56C frame with C-face mount simplifies installation
Three-phase motor for continuous duty
The Dayton 31LH67 is a 1.5 HP three-phase motor rated for continuous operation at 3510 RPM. It suits OEMs and maintenance teams needing a standard frame 56C motor for pumps, fans or conveyors in industrial settings.
Rigid base and C-face mounting simplify installation
The motor combines a rigid base with a C-face mount, allowing direct coupling or foot mounting without extra adapters. Ball bearings and Class F insulation support reliable running at up to 40 °C ambient temperature.
Dual-voltage design limits wiring options
Operation is fixed at 230/460 V AC, 60 Hz with full-load currents of 3.7 A and 1.9 A respectively. The 1.15 service factor provides modest overload margin, but the motor has no built-in thermal protection, so external overload devices are required.

Questions about this item
What maintenance will the ball bearings need over time?
The motor uses sealed ball bearings that are lubricated for life, so no periodic greasing is required under normal operating conditions.
Which limit appears first during continuous full-load operation?
The 1.15 service factor allows brief overloads, but sustained full-load running is limited by the 40 °C maximum ambient temperature rating.
How much heat and power draw should I expect when it runs all day?
At 84 % nominal efficiency the motor converts most input power to mechanical work; continuous duty at 1.5 HP on 230/460 V draws 3.7/1.9 A full-load current.
