Dayton 4VAG6BG Capacitor-Start Motor 1/2 HP 1725 RPM 115/208-230V 56 Frame

SKU CH-N90Z-B2HKE

Capacitor-start motor delivers 1/2 HP at 1,725 RPM on 115/208-230 V single-phase power in a 56 frame

  • Capacitor-start design delivers strong starting torque
  • 1/2 HP output handles demanding pump applications
  • Dual-voltage 115/208-230V wiring fits common supplies
  • Open dripproof enclosure suits dry indoor locations
  • Auto thermal protection guards against overheating

1/2 HP Capacitor-Start Motor

This Dayton 4VAG6BG motor delivers 1/2 horsepower at 1725 RPM for belt-drive applications. It operates on single-phase 115/208-230V AC power at 60 Hz. The 56 frame size fits standard cradle-base mounts. It suits pumps, fans, and light industrial equipment needing reliable starting torque.

Voltage and Service Factor Limits

Dual-voltage wiring allows 115V or 208-230V supply with 8.2 or 4.1 full-load amps respectively. The 1.15 service factor provides a modest margin for intermittent overloads. Continuous duty rating means it can run without rest periods. Automatic thermal protection resets after cooling. These electrical boundaries define safe operating envelopes.

Open Dripproof Steel Frame

Rolled steel construction with open dripproof enclosure resists falling debris while allowing airflow. The 5/8 inch shaft accepts standard pulleys or couplings. Cradle base mounting works in any angular position for flexible installation. Class B insulation tolerates up to 60°C ambient temperature. Reversible rotation simplifies drive alignment.

Questions about this item

Should I choose the 115 V or the 208-230 V wiring for my 1/2 HP motor?

Wire it for 115 V if your supply is 115 V; the motor will draw 8.2 A at full load. Wire it for 208-230 V if your supply is in that range; the draw drops to 4.1 A.

What does the 1725 RPM nameplate speed mean once the motor is under load?

The nameplate rating is 1,725 RPM at 60 Hz. With the 1.15 service factor the motor can handle short overloads, but continuous loaded speed will settle slightly below that figure.

How does the 56 frame and 5/8 in shaft affect mounting and coupling?

The NEMA 56 frame fixes the bolt pattern and shaft height. The 5/8 in diameter shaft accepts standard 56-frame pulleys, couplings or pump adapters.
