Motor Specifications

This 7.5HP single-phase electric motor runs at 3450 RPM on 230V 60Hz power and draws 31.6 amps at full load. It uses a 184T frame with a 1-1/8" keyed shaft that is 2.75" long and has a 0.25" keyway. The open drip-proof enclosure suits clean, dry environments.

Target Installers

The motor fits air compressor replacements that require the exact 184T frame dimensions and shaft profile. It is not for buyers who need a three-phase design, a different voltage, or a shaft diameter other than 1-1/8". The 60.0 amp circuit breaker requirement also rules out service panels that cannot supply that capacity.

Included Hardware

The package contains only the motor unit itself. No mounting bolts, pulleys, wiring harnesses, or circuit breakers are supplied, so the installer must source a 60.0 amp breaker and any drive components separately. The reversible CCW/CW rotation is factory set to CCW and can be changed during wiring.

Questions about this item

What circuit-breaker rating do I need on my 230 V supply for this 31.6 A motor?

The motor draws 31.6 A at full load, so the installer must provide a 60.0 A circuit breaker.

Will the 1-1/8" keyed shaft and 184T frame bolt onto my existing compressor pulley?

The shaft diameter is 1-1/8" with a 0.25" keyway and 2.75" usable length on an 184T frame; match those dimensions to your pulley hub.

How can I confirm the motor is running at the correct 3450 RPM after wiring?

With power applied, measure shaft speed with a tachometer; it should read 3450 rpm at 60 Hz.
