Three Phase Compactor Motors

What this page covers

Three phase motors run the vast majority of full-size industrial compactor installations — every stationary compactor over 5 yards, every self-contained compactor, every industrial waste-transfer-station setup. The standard horsepower range (5-25HP) covers everything from small stationary commercial to heavy-duty industrial cycling.

PRT three phase motors are NEMA TEFC with standard frame sizes (182T, 184T, 213T, 215T, 254T) used across compactor brands. They drop into Marathon, PTR, Wastequip, Harmony, SP Industries, and most other industrial compactor mounting locations.

How to choose

Match by horsepower (5, 7.5, 10, 15, 20, 25HP), voltage (208V, 230V, 480V), frame size (NEMA 182T, 184T, 213T, 215T, 254T), and shaft configuration (close-coupled to pump or foot-mount with belt drive).

For older compactors with discontinued OEM motors, PRT can recommend modern equivalents that drop into the existing pump assembly. Frame sizes are largely standardized across motor brands.
