5 HP 1 Phase Compressor Duty Electric Motor 1765 RPM 184T Frame 208-230V ODP CDM5-18-184T
Regular price
$659.95
The WorldWide Electric CDM5-18-184T is a 5 HP single-phase air compressor duty electric motor built to handle the high starting load and torque that air compressors demand. Its capacitor-start, capacitor-run design gets a loaded pump turning without bogging down, it runs on 230V or 208V service, and it can be wired to run in either direction (CW or CCW).
Replacing a compressor motor? Match the frame, shaft, and mounting to your existing motor — and if you change the RPM, resize the pulley or sheave to keep your compressor's CFM. Not sure it will fit your setup? Contact us with your old motor's nameplate and we'll confirm the right replacement before you buy.
Backed by a 2-year WorldWide Electric limited manufacturer's warranty from the invoice date. We package every motor carefully so it arrives ready to install, and we stand behind every sale. Questions about fit or specs? Get in touch.
Recommended magnetic starters
A magnetic starter protects this motor from overload and lets a pressure switch turn it on and off. Sized to match this motor.
