Ankara, with its defence industry, machine manufacturing and dense production zones such as OSTİM, generates strong demand for high-efficiency electric motors. For bench, pump and fan motors running long hours, efficiency class sits at the top of the selection criteria because it directly affects the electricity bill.

How Efficiency Class Affects the Bill

Among IEC 60034-30-1 efficiency classes, IE3 Premium and IE4 Super Premium markedly reduce losses compared with IE1. On a pump motor turning 16 hours a day, a few percentage points of efficiency translate into a meaningful drop in annual energy consumption.

Selection for OSTİM and Ankara Industry

Machine workshops and automation lines mostly use 4-pole (1500 rpm) IE3 motors. In systems running under continuous or variable load, pairing IE3/IE4 motors with a frequency inverter raises efficiency even further.

Technical Features and Durability

Class F insulation and IP55 protection are standard on high-efficiency motors; the cast iron housing dissipates heat in continuous service and preserves winding life. B3 foot or B5 flange mounting fits bench and pump installations.
