IE5 Ultra Premium is the highest efficiency tier defined by the IEC 60034-30 family and pushes the limits of conventional asynchronous design. The DRG Motor IE5 series uses an electromagnetic design that minimises losses at the core and winding level, bringing energy consumption on continuously running industrial lines below that of IE3 and IE4 equivalents.

What Does the IE5 Class Mean?

IEC 60034-30-1 and the extended 30-2 grade efficiency from IE1 Standard up to IE5 Ultra Premium. Each step means lower losses at the same power and speed. At the IE5 level the rotor, stator laminations and winding copper are optimised to cut magnetic losses.

Where It Makes a Difference

On pump, fan and compressor lines running more than 6,000 hours a year, the energy a motor consumes over its life far exceeds its purchase price. The IE5 series lowers total cost of ownership in these duties; lower losses also mean less heating and a longer insulation life.

Technical Specifications

DRG IE5 motors are offered on a 400 V / 50 Hz supply in 2-pole 3000 rpm and 4-pole 1500 rpm versions. F-class insulation, IP55 protection, S1 continuous duty and B3/B5/B14 mounting are standard, and the cast iron frame safely carries vibration and thermal load.

Choosing the Right IE5 Motor

Moving up to IE5 pays back fastest on lines that run long hours and are driven by a variable frequency drive. DRG Motor reviews your operating hours and load profile to decide together which ratings make sense to cover with IE5 rather than IE4.
