  • 2 HP three-phase power drives demanding industrial equipment
  • 230/460 V dual-voltage design simplifies wiring across facilities
  • 3500 RPM nameplate speed suits high-speed pump and fan duties
  • 5 % nominal efficiency lowers energy cost during continuous operation
  • Totally enclosed fan-cooled steel frame withstands 40 °C ambient conditions

Motor Specifications

The Dayton 36VF70 is a three-phase general purpose motor rated at 2 HP with a 143/5TC frame. It operates on 230/460V AC at 60 Hz and delivers a nameplate speed of 3500 RPM. The totally enclosed fan cooled design uses steel frame construction with ball bearings and includes a conduit box.

Application Fit

This motor suits equipment requiring a C-face mounted, 2 HP three-phase drive with 1.15 service factor and Class F insulation. It is not for single-phase power supplies, applications needing built-in thermal protection, or installations where the 40 °C maximum ambient temperature is exceeded.

Critical Specification

The dual-voltage rating of 230/460V AC with corresponding full-load currents of 5.1 and 2.5 amps determines whether this motor matches the available supply and starter sizing.

Questions about this item

Will the 143/5TC frame and 3500 RPM nameplate speed match the mounting pattern and shaft speed of the 1.5 HP motor I am replacing?

The 143/5TC frame uses standard NEMA C-face dimensions and the 3500 RPM rating aligns with typical 2-pole motor speeds, so it fits existing mounts and maintains shaft timing.

How can I verify the motor is running at the rated 85.5 percent efficiency after installation?

Measure line current at full load; it should read close to 5.1 A at 230 V or 2.5 A at 460 V with a 1.15 service factor and the motor should stay below the 40 °C ambient limit.

Does the included conduit box cover all wiring needs or must I supply separate thermal overload protection?

The conduit box is included, but the motor has no built-in thermal protection, so external overload relays or a starter with overload must be provided separately.
