The 5.5 kW electric motor covers the standard power requirement of small and medium machinery and is commonly built in the IEC 132S frame size. This power class is frequently chosen for compressors, booster pumps, fans, conveyors and woodworking machines. DRG Motor supplies the 5.5 kW rating in various pole counts and efficiency classes from its Izmir production.

Speed and Torque Values

The 2-pole version of the 5.5 kW rating offers high speed and lower torque at around 2900 rpm, while the 4-pole model produces higher torque at about 1450 rpm. The 6-pole option, at 960 rpm, suits mixer and elevator duties that need high torque at low speed. Rated current on a 400 V supply is roughly 11 A.

Why the Efficiency Class Matters

At a continuously running rating such as 5.5 kW, the efficiency class makes a clear difference to the annual energy bill. An IE3 Premium model saves a meaningful amount over the year compared with an IE1 standard unit, while IE4 Super Premium runs with even lower losses. In plants that operate around the clock, the difference can offset the purchase price within a few years.

Frame and Mounting Options

5.5 kW motors are available foot-mounted B3, flange-mounted B5 or face-mounted B14. A cast iron frame withstands vibration in grinding and crushing environments, while an aluminium frame eases installation on pump sets. IP55 protection and Class F insulation mean safe operation in dusty and humid conditions.
