YEJVFSeries Motor Model
The YEJVF Series represents a specialized line of three-phase asynchronous motors with integrated electromagnetic braking systems, designed for applications requiring precise stopping and reliable holding torque under load. These motors combine high-efficiency power transmission with instant braking capabilities, making them ideal for machinery where safety and positional accuracy are critical, such as cranes, hoists, conveyors, elevators, and packaging equipment. Key features include a robust cast-iron or aluminum frame (depending on power rating) with IP55 protection, ensuring resistance to dust and moisture ingress. The electromagnetic brake, activated upon power cutoff, provides rapid, non-contact stopping, eliminating mechanical wear and enhancing operational safety. The brake system operates silently and requires minimal maintenance, with adjustable torque settings to suit varying load demands. The YEJVF Series supports power ratings from 0.55 kW to 22 kW and voltage compatibility of 380V–440V, accommodating global industrial standards. Speed options range from 900 r/min to 2,900 r/min, with 2-pole and 4-pole configurations available. Compliant with IE2/IE3 efficiency standards, these motors reduce energy consumption while delivering stable performance under continuous or intermittent duty cycles. Additional advantages include low vibration, thermal overload protection, and optional accessories like encoders or space heaters for enhanced control in harsh environments. With their compact design, rapid braking response, and durability, the YEJVF Series motors offer a cost-effective solution for industries prioritizing safety, precision, and reliability in motion control applications.

The YEJVF series motor is a high-efficiency variable frequency asynchronous motor specially developed for integration with reducers in precision-controlled industrial scenarios. It adopts a closed-type structure, optimized winding design and frequency conversion adaptation technology, enabling stable operation under wide frequency regulation range while matching the speed and load requirements of reducer-driven equipment.
A core advantage lies in its excellent frequency conversion performance and seamless coordination with reducers. The motor maintains low torque ripple and high speed stability during frequency adjustment, effectively reducing mechanical impact on reducer gears and extending the service life of the entire transmission system. It supports stepless speed regulation from low to high speed, meeting the flexible operation needs of equipment such as precision conveyors, automated production lines and precision mixers.
Equipped with F-class insulation and IP55 protection rating, it features strong resistance to dust, moisture and high temperature, adapting to harsh and complex industrial environments. The built-in temperature monitoring device prevents overheating, ensuring safe and continuous operation. Its high energy efficiency ratio under variable frequency conditions and low noise emission significantly reduce long-term operational costs.
With compact structure, standardized mounting dimensions and strong overload capacity, it is highly compatible with various types of reducers. This combination of precise frequency conversion control, reliable reducer adaptation and high operational efficiency makes it an ideal drive core for high-precision mechanical transmission systems.
