IE4 Electric Motors

DRG MOTOR – IE4 Electric Motors
IE4 Premium Plus Efficiency
DRG MOTOR introduces IE4 class electric motors to Turkey, maximizing energy efficiency for industrial applications. Also known as “Super Premium Efficiency,” IE4 motors provide up to 10% additional energy savings compared to IE3 motors.
IE4 – More power with less energy.
These motors are fully compliant with EU Ecodesign 640/2009 & 2019/1781 directives and recognized as the future mandatory efficiency standard in Turkey.
What is IE4?

Efficiency Class	Definition	Status in Turkey
IE1	Standard Efficiency	Prohibited
IE2	High Efficiency	Import prohibited
IE3	Premium Efficiency	Current mandatory class
IE4	Super Premium Efficiency	Next-generation high-efficiency standard

IE4 motors achieve higher efficiency through optimized rotor and stator design, higher copper winding ratio, and geometry that minimizes energy losses, producing the same torque as IE3 motors with less energy.
