Dayton 5FTR9 Capacitor-Start Motor 1/2 hp 1/7 hp 115V AC 56 Frame

SKU CH-ZF42-7SJFY

Dual-speed capacitor-start motor delivers 1/2 hp at 1,725 RPM and 1/7 hp at 1,140 RPM on 115 V AC with a 56 frame cradle base

  • Dual-speed flexibility with 1,725 and 1,140 RPM options
  • Reliable capacitor-start design for single-phase 115 V AC supply
  • Service factor 1.25 handles continuous-duty overloads
  • Open drip-proof enclosure suits indoor installations
  • Keyed 56-frame shaft fits standard mounting configurations

Motor Design and Power

The Dayton 5FTR9 is a capacitor-start general-purpose motor rated at 1/2 hp and 1/7 hp for dual-speed operation. It runs on 115V AC single-phase power at 60 Hz and fits a standard 56 frame. The open drip-proof enclosure and cradle-base mounting suit all-angle installation in dry, ventilated locations.

Suitable Applications and Limits

This motor suits equipment needing two fixed speeds such as fans, blowers or light-duty machinery where 1,725 RPM and 1,140 RPM match the load. Buyers who require thermal overload protection, a totally enclosed enclosure or operation above 40 degrees Celsius ambient should look at other models.

Deciding Specification

The dual horsepower rating of 1/2 hp at 7.1 A and 1/7 hp at 3.7 A with a 1.25 service factor determines whether the motor can deliver the needed torque continuously on a 115V supply.

Highlights

  • Dual-speed flexibility with 1,725 and 1,140 RPM options
  • Reliable capacitor-start design for single-phase 115 V AC supply
  • Service factor 1.25 handles continuous-duty overloads

Questions about this item

Will the 56 frame and cradle-base mounting let me bolt this motor onto the same brackets as my old 56-frame unit?

Yes — the motor uses a standard 56 frame with cradle-base mounting and all-angle positioning, so it fits existing 56-frame brackets and can be rotated to match the old shaft height.

How can I confirm the motor is delivering both speeds correctly after wiring?

Run the motor unloaded and measure shaft speed; you should see approximately 1,725 RPM on the high-speed winding and 1,140 RPM on the low-speed winding at 60 Hz.

Does the box include a start capacitor, mounting bolts or a wiring diagram, or must I source them separately?

The motor ships as the bare unit only; a compatible start capacitor, mounting hardware and wiring diagram are not included and must be purchased separately.
