Description
The YE4 series represents China’s super premium efficiency (IE4) class of three-phase asynchronous AC induction motors, designed and manufactured to meet both international IEC 60034-30-1 and Chinese GB 18613-2020 (Level 2) efficiency standards. These motors feature a fully enclosed, self-ventilated (IC411) squirrel-cage rotor construction with robust cast iron frames, delivering exceptional performance across a wide range of industrial applications.
Available in frame sizes from H80 to H355 with power ratings spanning 0.75kW to 375kW (standard), YE4 motors operate at 380V/50Hz as standard (custom voltage options available) and are designed for continuous duty (S1 工作制). Key technical specifications include Class F insulation and IP55 protection rating, ensuring reliable operation in harsh industrial environments while providing excellent thermal resistance and dust/water protection.
What distinguishes the YE4 series is its optimized electromagnetic design incorporating high-quality copper windings, low-loss electrical steel laminations, and precision-balanced rotors, resulting in significantly reduced energy consumption compared to previous YE3 series motors. Additional advantages include low noise levels, minimal vibration, high starting torque, and easy maintenance, with installation dimensions fully compliant with IEC standards for seamless retrofitting.
These versatile motors find widespread application in various industries including manufacturing, water treatment, HVAC, mining, and agriculture, ideally suited for driving pumps, fans, compressors, machine tools, conveyors, and other general-purpose mechanical equipment requiring continuous, energy-efficient operation. As a cornerstone of industrial energy-saving initiatives, the YE4 series offers businesses a cost-effective solution to reduce operational expenses while meeting increasingly stringent environmental regulations.
