YDF-WF-121-4 Three-Phase Asynchronous Motor Product Introduction

YDF-WF-121-4 is a specialized three-phase asynchronous motor designed specifically for electric valve actuators. Integrating core advantages such as high efficiency, energy saving, reliable protection, and strong adaptability, it is an ideal power source for industrial valve automation control scenarios. It is widely used in industries such as electric power, chemical engineering, petroleum, metallurgy, and water treatment, providing stable and precise power support for valve opening, closing, and regulation.

The motor adopts a 4-pole design with a synchronous speed of 1500r/min. Its rated power is adapted to the conventional operating conditions of electric actuators. It runs smoothly with uniform torque output, capable of precisely matching the opening/closing speed and torque requirements of valve actuators. This avoids valve stalling and overshooting caused by speed fluctuations, ensuring valve regulation precision and operational stability. Its core structure uses a laminated stator core of high-permeability silicon steel sheets, paired with high-quality pure copper windings, effectively reducing iron loss and copper loss. The motor efficiency reaches National Standard Level 2 or above. Compared with ordinary asynchronous motors, its operating energy consumption is reduced by 10%-15%, which can significantly reduce corporate electricity costs over long-term use, aligning with the development trend of energy saving and consumption reduction in the industrial field.

Protection performance is a core highlight of the YDF-WF-121-4. The whole machine adopts a WF-grade protection design. The housing is made of high-strength aluminum alloy die-casting, and the surface is treated with electrostatic spraying for corrosion resistance. It possesses excellent moisture, dust, and corrosion resistance capabilities, with a protection rating of IP55, capable of adapting to industrial environments with humidity, dust, and mild corrosive gases. The internal windings of the motor are impregnated with high-temperature resistant insulating varnish, with an insulation class of F and a heat resistance temperature of 155°C. Even under continuous operation and conditions with large ambient temperature fluctuations, it can maintain stable insulation performance, eliminating risks of short circuits and leakage, thereby greatly improving motor operational safety and service life.

To accommodate the installation requirements of electric valve actuators, the YDF-WF-121-4 adopts a standardized flange mounting structure. Its installation dimensions are fully compatible with mainstream electric actuators (such as DZW and DKJ series), allowing direct connection without additional modification. Installation is convenient and versatility is strong. The tail of the motor integrates a high-precision centrifugal switch, enabling precise switching of motor start and run states. Cooperating with the actuator control system, it can respond quickly to valve opening and closing commands, with short start response time and no operational lag, meeting the demand for rapid valve regulation in industrial processes. At the same time, the motor has a built-in overheat protection device. When the winding temperature exceeds the safety threshold, it automatically cuts off the power, avoiding motor burnout caused by overload or stalling, reducing equipment maintenance costs and the risk of failure downtime.

In terms of operational stability, the YDF-WF-121-4 uses low-noise bearings and precision dynamic balancing technology. The motor operates with low vibration and low noise (≤65dB), complying with environmental requirements for industrial sites and reducing interference with surrounding equipment and operators. Its insulation system has undergone rigorous moisture and mildew proofing treatment, capable of long-term stable operation in environments with humidity below 90%, fearless of special conditions such as rainy seasons and humid workshops. In addition, the motor junction box adopts a sealed design with firm and reliable terminals, offering excellent waterproof and dustproof performance. On-site wiring operations are simple, adapting to various installation scenarios such as outdoor and semi-outdoor.

YDF-WF-121-4 is strictly produced in accordance with the national standard GB/T 755 "Rotating Electrical Machines - Rating and Performance". Each motor undergoes factory testing, including no-load tests, load tests, insulation resistance tests, and temperature rise tests, ensuring stable product performance and reliable quality. Relying on advantages such as high efficiency, energy saving, reliable protection, strong adaptability, and stable operation, this motor has become the mainstream supporting power equipment for electric valve actuators. It helps industrial automation systems achieve efficient, safe, and stable operation and is a trusted core component in the field of industrial valve control.
