  • weight30.95
  • typeClosed Base
  • 1 hp motor drives demanding machinery
  • Capacitor-start/run design delivers strong starting torque
  • Dual-voltage 115/208-230V suits multiple power supplies
  • 56 frame fits standard industrial mounting patterns
  • Auto thermal protection prevents overheating damage

Capacitor-Start/Run 1 hp Motor

This Dayton 31TR94 is a single-phase general-purpose motor rated at 1 hp for continuous-duty machinery. It suits OEM equipment, replacement projects and light-industrial drives that need a rigid-base, open drip-proof unit.

Dual-Voltage 115/208-230V Operation

The nameplate voltage of 115/208-230V AC at 60 Hz decides fit; full-load current is 8.8 A at 115 V or 4.9-4.4 A at the higher voltages. Service factor 1.25 and automatic thermal protection support sustained loads.

56 Frame Rigid-Base Integration

The 56 frame with closed base and CW/CCW reversible shaft mounts at any angle, freeing the builder from orientation constraints. It needs a 208-230 V supply or 115 V circuit, capacitor-start/run wiring and a driven load matched to 3,450 RPM.

Questions about this item

What does the 1 hp rating actually deliver on a 115 V supply?

At 115 V the motor draws 8.8 A full-load current and runs continuously at 3,450 RPM with a 1.25 service factor.

How does the 115/208-230 V dual-voltage design affect the current draw?

Full-load amps are 8.8 A at 115 V and 4.9–4.4 A at 208–230 V, all on 60 Hz single-phase power.

Will the 56-frame rigid base bolt onto my existing mounting plate?

The motor uses a NEMA 56 frame with rigid base mounting and weighs 30.95 lb, suitable for all-angle installation.
