Motor Application
The Dayton 30PT93 is a three-phase general purpose motor rated at 1-1/2 HP for 230/460V AC operation. It suits industrial equipment such as pumps, fans, conveyors and machine tools that require continuous duty at 3,450 RPM. Buyers needing single-phase power, a different horsepower rating or a totally enclosed enclosure should look elsewhere.
Voltage and Frame Fit
The critical specification is the dual-voltage 230/460V three-phase input combined with a NEMA 56 frame. Full-load current draws 4.2 amps at 230V or 2.1 amps at 460V, and the 1.15 service factor provides a modest overload margin. Verify that your supply voltage, starter sizing and frame mounting pattern match these values before ordering.
Installation Notes
The rigid steel base bolts directly to a flat mounting surface using the standard 56 frame footprint. Ball bearings are factory lubricated for the 40 °C maximum ambient temperature. No thermal protection is built in, so external overload protection must be supplied by the starter or controller. Confirm rotation direction (CW/CCW) during commissioning and ensure wiring matches the selected voltage.

Questions about this item
What does the 1 1/2 HP rating mean for actual output on a shop machine?
The motor delivers 1 1/2 horsepower at the shaft with a 1.15 service factor, allowing brief overload up to roughly 1.7 HP while running at 3,450 RPM.
How does the 230/460V dual-voltage design affect the wiring I must use?
The nine-lead winding lets you wire for either 230 V or 460 V three-phase supply; full-load current is 4.2 A at 230 V or 2.1 A at 460 V, so size conductors and overloads accordingly.
Will the 56 frame and rigid base bolt directly to my existing mount?
Yes — the NEMA 56 frame has standard foot-hole spacing and a closed-base steel frame, so it drops onto any 56-pattern rigid mount without adapters.
