General Purpose Motor for Fan Accessories
The Dayton 4K811 is a single-phase capacitor-start motor rated at 1 hp and 1730 rpm. It operates on 115/208-230V AC at 60 Hz with a 145TC frame and open drip-proof enclosure. Designed for continuous duty, it suits replacement or new-build fan accessory projects.
Upgrade from Lower Output or Worn Units
This motor replaces units with less than 1 hp output or those lacking a 1.15 service factor. The jump is worth it when the application demands continuous operation at up to 40 degrees C ambient and a rigid C-face mounting base. It also supports usable 208V supply where older motors may not.
Check Voltage, Frame and Mounting Before Ordering
Verify that your supply matches 115V or 208-230V and that the 145TC frame fits the existing mounting pattern. Confirm the shaft rotation requirement suits CW/CCW reversible operation. Note the motor has no thermal protection and carries Proposition 65 warnings for cancer and reproductive harm.

Questions about this item
What frame size and mounting style does the 145TC motor need?
The motor uses a 145TC frame with C-Face rigid base mounting and can be installed at any angle.
How do I wire the capacitor-start motor for 115 V or 208-230 V operation?
Connect the leads for 115 V at 14.8 A or 208-230 V at 7.5-7.3 A following the diagram on the nameplate; the motor runs at 1,725 rpm.
What ongoing care does the open drip-proof motor with Class B insulation require?
Keep the 40 °C max ambient clean, ensure ventilation stays clear, and monitor bearing noise since there is no thermal protection.
