A 5.5 kW three-phase electric motor is one of the most common ratings in small-to-medium pump, fan, compressor and machine-building applications. Its price is not a fixed figure; it varies with the choice of speed, frame and efficiency class.

Typical Specifications of a 5.5 kW Motor

A 5.5 kW motor runs on a 400 V / 50 Hz supply and draws about 11 A at full load. The 4-pole version turns at 1500 rpm and the 2-pole at 3000 rpm. This rating is usually built in frame size 132 with an aluminium or cast iron frame.

Choices That Affect the Price

At the same 5.5 kW, an IE3 motor costs more than IE2 because it contains more copper, but its running cost is lower. A cast iron frame raises the price over aluminium, and a flange (B5) mounting over a foot (B3) mounting.

Why Speed Choice Matters

For 5.5 kW centrifugal pumps a 2-pole 3000 rpm is typical, while fans and conveyors favour a 4-pole 1500 rpm. The wrong speed needlessly raises both price and energy use, so the choice should start from the application.

A Current Quote for 5.5 kW

Once speed, frame material and mounting type are set, DRG Motor gives a current, clear price for your 5.5 kW motor. Sharing the application details is the fastest route to both the right model and the best quote.
