Dayton 20VD22 1/3 HP Three-Phase Motor

The Dayton 20VD22 is a 1/3 HP three-phase general purpose motor built on a 56 frame with a rigid steel base. It suits industrial HVAC equipment and machinery that need continuous duty at 1,725 RPM. The open drip-proof enclosure and Class B insulation handle ambient temperatures up to 40 °C. Rotation is reversible CW/CCW for flexible installation.

Dual-Voltage 230/460V AC Operation

The motor runs on 230/460V AC at 60/50 Hz, drawing 1.2 A at 230 V or 0.60 A at 460 V under full load. A service factor of 1.35 provides margin for intermittent overloads, while ball bearings support the shaft. No internal thermal protection is fitted, so external overload protection must be supplied by the installer. Nominal efficiency is 73.4 percent at rated load.

Frame 56 Compatibility Decides Fit

Frame 56 defines the mounting footprint, shaft height and shaft diameter, so the motor only fits equipment designed for that NEMA frame size. Buyers whose application calls for a different frame designation cannot use this unit. Verify the driven equipment nameplate matches 56 frame, 1/3 HP and 1,725 RPM before ordering.

Questions about this item

Should I pick the 230 V or 460 V connection for my supply?

The motor is dual-voltage; wire it for 230 V AC and it draws 1.2 A, or wire it for 460 V AC and it draws 0.60 A.

What does the 1/3 HP rating deliver on the shaft?

At 1,725 RPM the motor produces its rated 1/3 horsepower continuously with a 1.35 service factor for occasional overload.

How does the 60/50 Hz rating affect speed and voltage?

At 60 Hz the nameplate speed is 1,725 RPM on 230/460 V; at 50 Hz the synchronous speed drops proportionally while the same voltage taps are used.
