PRPDUCT INTRODUCTION

The IE4 series 3 phase AC induction motors refer to ultra-high energy efficiency motors as defined in the IEC 60034-30-1 standard. They offer significant energy savings, achieving an energy efficiency level of IE4. The energy efficiency of IE4 motors is 20%-30% higher than that of IE3 motors and 30%-50% higher than that of IE2 motors. The energy efficiency of IE4 motors far exceeds the first-level energy efficiency standard in the national standard GB 18613-2012.

IE4 motors are suitable for operating conditions with high requirements for energy efficiency and long-term economic efficiency.
