Black industrial electric motor with cooling fins and rigid base

Dayton

Dayton 36VF28 GP Motor TEFC 3 HP 1765 rpm 1-1/8in shaft

SKU CH-7MS5-GE4AJ

Three-phase TEFC motor delivers 3 HP at 1765 rpm with a 1-1/8 in keyed shaft for rigid-base mounting

  • TypeTemperature Controllers
  • 3 HP power drives demanding HVAC applications
  • TEFC enclosure protects motor in harsh environments
  • 1765 rpm speed suits standard 60 Hz systems
  • 208-230/460 V dual voltage fits common supplies
  • 15 service factor handles temporary overloads

General-purpose three-phase motor

The Dayton 36VF28 is a totally enclosed fan-cooled motor rated at 3 HP and 1765 rpm. It operates on 208-230/460 V at 60 Hz with a 1-1/8 inch keyed shaft. The 182/4T frame uses rolled steel construction and ball bearings for rigid base mounting.

Suited for fixed-speed industrial drives

This unit fits equipment needing a single-speed, horizontally mounted motor with Class F insulation and a 1.15 service factor. It is not for applications requiring variable speed control, vertical mounting, built-in thermal protection or multi-voltage configurations outside the stated range.

Delivers 3 HP continuous at 40 °C ambient

At nameplate conditions the motor draws 8.4-7.6/3.8 full-load amps and provides 15 percent overload capacity through its service factor. Headroom ends when ambient temperature exceeds 40 °C or when the load demands more than the 1.15 factor allows.

Questions about this item

What three-phase voltage supply do I need for the 208-230/460 V motor?

The motor runs on 208-230 V or 460 V three-phase power at 60 Hz; full-load current is 8.4-7.6 A on the low voltage and 3.8 A on the high voltage.

Will the 182/4T rigid-base frame bolt onto my existing 182T mounting pattern?

Yes, the 182/4T frame shares the standard 182T bolt pattern, so the rigid base fits existing 182T mounting holes without modification.

How can I verify the motor is delivering its rated 3 HP after installation?

Measure line current under load; it should read close to 7.6 A at 230 V or 3.8 A at 460 V while the shaft turns near 1765 rpm.
