Farm-Duty Motor for Continuous Aeration
The Dayton 4K062 is a 3 hp capacitor-start motor built for farm-duty aeration fans that require continuous operation. It runs on 230V AC single-phase power at 60 Hz and fits a 145TZ steel frame with a rigid base for horizontal mounting. The enamel-coated enclosure is totally enclosed air-over, and the shaft rotates in either direction to suit the driven equipment.
Thermal Protection and Power Draw
Auto-reset thermal protection and Class B insulation allow a maximum ambient temperature of 50 Degrees C during continuous duty. At full load the motor draws 14.9 A with a 1.0 service factor, delivering nameplate speed of 450 RPM under normal operating conditions. The capacitor-start design provides the starting torque needed for fan loads without additional starting gear.
Sustained Load Behaviour
Under sustained load the motor maintains its 450 RPM rating continuously thanks to the continuous duty cycle rating and air-over cooling. The auto thermal protector will interrupt power if internal temperature exceeds the design limit, then restore operation once the motor cools. This behaviour supports uninterrupted aeration cycles without the performance drop-off seen in intermittent-duty designs.

Questions about this item
How do I wire the 230 V AC supply to the capacitor-start motor and which step is most often missed?
Connect the 230 V AC lines to the motor terminals and the start capacitor as shown on the nameplate diagram; the step most often missed is securing the capacitor leads and verifying rotation before final tightening.
What maintenance will the 145TZ frame motor need over its service life?
Inspect the totally enclosed air-over enclosure for debris, check the enamel-coated steel frame for corrosion, and verify the auto thermal protection resets correctly during routine service intervals.
At what point does the 50 °C maximum ambient temperature limit performance during continuous duty?
When the surrounding air exceeds 50 °C the motor’s insulation class B and service factor 1.0 leave no thermal margin, so the auto thermal protection will trip first under sustained load.
