3HP 230V Air Compressor Motor

This 3HP single-phase motor runs at 3450 RPM on 230V 60Hz power, drawing 15.5A at full load. It is built for air compressor replacements or custom builds that need a 56 frame footprint and reversible rotation. The factory setting is counter-clockwise but it can be wired for clockwise operation.

Open Drip-Proof Steel Frame and Keyed Shaft

The motor uses an open drip-proof enclosure suited for clean, dry environments and a sturdy steel frame that aids heat dissipation. A 5/8 inch keyed shaft with 1.88 inch length and 0.188 inch keyway provides a secure mechanical connection to pulleys or couplings. The unit weighs 29.3 lbs and measures 9.25 inches wide.

Single-Phase Power and Protection Requirements

Operation requires a 230V single-phase supply and a customer-supplied 40 amp circuit breaker for safe protection. The service factor is 1.0, so the motor should not be loaded beyond its 3HP nameplate rating. The ODP design limits use to locations free from excessive moisture, dust or corrosive fumes.

Questions about this item

Does the 230 V 60 Hz single-phase supply limit the motor to 15.5 A full-load current?

Yes, the motor draws 15.5 A at full load on a 230 V 60 Hz single-phase circuit.

Will a NEMA 56 frame with a 5/8" keyed shaft and 1.88" shaft length bolt directly to my compressor?

The motor uses a standard 56 frame, 5/8" keyed shaft with 1.88" shaft length and 0.188" keyway.

How do I reverse the factory CCW rotation to CW, and what wiring mistake should I avoid?

Swap the two main winding leads to change from factory CCW to CW; ensure the customer-supplied breaker is 40 A.
