Dayton 31LH41 1/3 HP three-phase motor 230/460V 56C frame
Three-phase general-purpose motor delivering 1/3 HP at 1160 RPM with 230/460V dual-voltage operation and 56C frame mounting
- Three-phase design delivers balanced power at 230/460 V AC
- 1/3 HP output with 1160 RPM suits continuous HVAC duty
- 56C C-face mounting simplifies direct coupling to pumps or fans
- Service factor 1.35 provides extra capacity for peak loads
- Class F insulation and ball bearings support 40 °C ambient operation
Application fit
The Dayton 31LH41 is a three-phase general-purpose motor rated at 1/3 HP for 230/460V AC supplies. It suits OEMs and maintenance teams that need a direct-drive unit for pumps, fans or conveyors where a C-face mount and continuous-duty cycle are specified.
Build and mounting
The open drip-proof steel frame carries ball bearings and Class F insulation with a 1.35 service factor. A 56C C-face flange provides direct coupling to driven equipment, while dual-voltage windings allow connection to either 230 V or 460 V three-phase networks.
Interface limits
The motor delivers 1160 RPM nameplate speed at 60 Hz with a nominal efficiency of 71.4 percent. Full-load current is 1.5 A at 230 V or 0.76 A at 460 V, and the design has no internal thermal protection. Operation is rated for a maximum ambient temperature of 40 degrees C.
