Dayton

Dayton 4GPT2 1-1/2 hp washdown motor 1750 RPM 230/460 VAC

SKU CH-ADD3-T5HT1

A 1-1/2 hp three-phase washdown motor running at 1750 RPM on 230/460 VAC with a 145TC frame and continuous duty cycle

  • TypeBrake Motors
  • 5 hp output drives demanding washdown applications
  • 1750 RPM at 60 Hz provides steady three-phase speed
  • Dual 230/460 VAC voltage fits common industrial supplies
  • 145TC frame matches standard NEMA mounting dimensions
  • Totally enclosed fan-cooled enclosure resists water and contaminants

Washdown Motor for Wet Environments

The Dayton 4GPT2 is a three-phase brake motor rated at 1-1/2 hp with a 1750 RPM nameplate speed. It operates on 230/460 VAC power and fits a 145TC frame. This motor suits food-processing, pharmaceutical or marine equipment that requires regular high-pressure cleaning. Buyers needing single-phase input or a different frame size should look elsewhere.

Thermal Performance in Normal Operation

The totally enclosed fan-cooled enclosure protects internal components from moisture and contaminants. Insulation Class F supports a maximum ambient temperature of 40 degrees Celsius. A 1.15 service factor provides a margin for intermittent overloads. No internal thermal protection is fitted, so external overload devices are required.

Behaviour Under Sustained Load

The motor carries a continuous duty cycle rating for uninterrupted operation. At full load it draws 4.0 amps at 230 VAC or 2.0 amps at 460 VAC. It is usable at 208 VAC but not at 200 VAC. NEMA Design B torque characteristics deliver consistent starting and running performance across 60/50 Hz supplies.

Questions about this item

How do I wire the 145TC frame washdown motor for 230 V or 460 V three-phase power?

Connect the nine leads per the nameplate diagram for 230/460 V; the motor draws 4.0 A at 230 V and 2.0 A at 460 V. Verify rotation is CW/CCW as needed before coupling.

What maintenance does the Dayton 1-1/2 hp washdown motor need over its service life?

The totally enclosed fan-cooled enclosure has no user-serviceable bearings or thermal protection; plan on periodic shaft-seal inspection and external cleaning only.

At what point does continuous duty at 1.15 service factor hit its thermal limit in a 40 °C ambient?

Class F insulation and 1.15 service factor allow continuous operation at nameplate load in 40 °C ambient; sustained overload beyond 1.15 × rated torque will exceed winding temperature limits first.
