Dayton 35Z917 1-1/2 HP 1755 RPM 208-230/460V blower

SKU CH-2S2Y-WY6DW

Three-phase 1-1/2 HP motor runs at 1755 RPM on 208-230/460V with a 1.25 service factor

  • 1-1/2 HP output drives demanding HVAC loads
  • 1755 RPM nameplate speed ensures steady airflow
  • Dual 208-230/460 V three-phase input fits common supplies
  • Totally enclosed fan-cooled frame protects windings in dusty environments
  • 25 service factor allows continuous duty with thermal margin

Three-phase farm-duty motor

The Dayton 35Z917 is a general-purpose three-phase motor rated at 1-1/2 HP with a nameplate speed of 1755 RPM. It operates on 208-230/460V AC at 60/50 Hz and fits a 143-5T/56HZT frame with rigid base mounting for horizontal installation.

Suited for continuous industrial drives

This motor suits equipment that runs continuously at a 1.25 service factor in ambient temperatures up to 40 °C. Insulation Class F and a totally enclosed fan-cooled enclosure protect windings in dusty or damp environments. Buyers needing single-phase power, variable-speed control or built-in thermal overload protection should look elsewhere.

Steady output under constant load

With a continuous duty cycle and no thermal protection, the motor delivers consistent torque as long as supply voltage stays within 230/460V and cooling airflow is unobstructed. Full-load current draws 4.3 A at 230 V or 2.1 A at 460 V, so wiring and upstream protection must be sized for sustained operation rather than brief peaks. The reversible CW/CCW rotation allows flexible coupling to driven equipment.

Questions about this item

What three-phase supply voltage does the 35Z917 motor require?

It is rated for 208-230/460 V AC at 60/50 Hz and draws 4.3/2.1 full-load amps.

Can the 143-5T/56HZT frame motor replace an older 56-frame unit on the same base?

The rigid-base mounting matches NEMA 143-5T and 56HZ dimensions, so existing bolt patterns should align.

How do I confirm the motor is running at the correct 1755 RPM after installation?

Measure shaft speed with a tachometer; it should read 1755 RPM at full load on a 60 Hz supply.
