YBDF-WF-412-4 Valve Dedicated Three-Phase Asynchronous Motor Product Introduction

YBDF-WF-412-4 is a high-performance three-phase asynchronous motor dedicated for valves, developed specifically for heavy-load valve driving scenarios in industrial pipeline systems. Integrating mature manufacturing processes with reliable safety designs, it adapts to special industrial environments such as petroleum, chemical, and natural gas, serving as the core driving component for large-bore, multi-turn electric valve devices. This motor is manufactured by professional vendors like Yangzhou Huatong and Yulin strictly in accordance with the JB/T 2195-1998 industry standard. It has passed ISO9001, CCC, and CE certifications, with quality fully meeting the requirements for long-term stable industrial applications.

Core Performance Parameters

The motor has a rated power of 5.5kW and a rated voltage of 380V (three-phase), adapting to mainstream industrial power supply systems; specifications such as 660V and 440V can be customized for special scenarios. The rated current is 14A, with stable operating current and excellent energy consumption control, fitting the intermittent short-time duty cycle characteristics of valves and meeting the 10min standard operating duration requirement. Its operating efficiency is superior to ordinary motors of the same power. The rated speed is approximately 1440r/min, which is the standard speed for a 4-pole motor. The opening and closing speed is moderate, allowing for precise control of the switching amplitude of large heavy-load valves and effectively protecting the valve sealing surface. The rotor adopts a slender design with small additional inertial load, ensuring smooth operation without jamming and significantly reducing impact damage during the valve opening and closing process.

Structural Design and Protection

The product structure balances durability and environmental adaptability. The frame is made of thickened cast iron, featuring high strength, vibration resistance, and corrosion resistance, capable of withstanding continuous impacts under heavy-load operation. The insulation class is F, offering excellent heat resistance and allowing a long-term operating temperature of up to 155°C. It can operate stably in ambient temperatures ranging from -15°C to +40°C and in areas below 1000m altitude. The insulation system effectively resists voltage fluctuations and environmental moisture erosion, significantly extending the motor's service life. The protection class reaches IP55, preventing dust intrusion and water jet effects, making it perfectly suitable for harsh operating environments such as outdoors, dampness, and dustiness. It adopts an end-face outlet structure without a junction box and uses a self-cooling design, simplifying the installation process, reducing external accessory failure points, and adapting to the integrated installation requirements of valve electric devices.

Specialized Performance Advantages

As a valve-dedicated motor, the YBDF-WF-412-412-4 possesses high starting torque and strong overload capability. The ratio of starting torque to rated torque exceeds 3.5 times, easily handling the high torque demand at the instant of valve opening and closing. It can withstand 2 times the rated torque in a hot state and 120% of the rated speed during no-load operation, perfectly adapting to the torque characteristics of valves which feature "high load at the instant of opening and closing, low load during intermediate operation," thereby avoiding equipment failures caused by load fluctuations. The motor windings are made of high-quality red copper, offering good conductivity and low loss, combining the advantages of high efficiency, energy saving, and stable output, fitting the trend of industrial energy-saving applications. The overall unit noise is ≤75dB (A), ensuring quiet operation and improving the working environment of industrial sites.

Applicable Scenarios and Customization

This motor has a wide range of applicable scenarios, mainly used in large pipeline systems in industries such as petroleum refining, chemical production, natural gas transportation, and sewage treatment. It drives heavy-load electric valve devices such as large-bore gate valves, globe valves, and butterfly valves, and can also be used in other industrial driving scenarios requiring high torque and intermittent operation. The product supports customization services; parameters such as voltage, speed, and installation method can be adjusted according to user needs. Standard installation methods such as B3, B5, and B35 are available to meet the installation adaptation requirements of different equipment. Output shafts and flange dimensions can be customized according to user equipment interfaces, enhancing on-site installation compatibility.

Quality Assurance and Maintenance

The YBDF-WF-412-4 motor undergoes strict factory testing before leaving the factory, including insulation tests, load tests, and temperature rise tests, ensuring that every product meets performance standards. The structure is simple and compact, and the parts have strong universality, making daily maintenance convenient without the need for complex maintenance procedures, thereby reducing later operation and maintenance costs and downtime. Relying on stable performance, reliable quality, and professional adaptation design, the YBDF-WF-412-4 has become a preferred product in the field of industrial valve driving, helping industrial pipeline systems operate safely, efficiently, and stably, and providing reliable power support for industrial automation control.
