With a rated power of 4KW (4000W), operating voltage of 380V three-phase AC, adjustable frequency range of 50-100HZ, and rotational speed of 2600 RPM, this motor is engineered to adapt to dynamic load requirements in heavy industries. Its standout features include a TEFC (Totally Enclosed Fan-Cooled) system, IP55 protection rating, and 34KG robust cast iron casing, which enable it to operate reliably in harsh environments (e.g., dusty mines, humid workshops). As an energy-saving solution, the motor reduces energy costs by 15-20% compared to fixed-speed motors, making it a preferred choice for machinery that requires frequent speed adjustments, such as machine tools and textile equipment. Additionally, it holds CSA security certification, ensuring compliance with international safety standards for industrial use.
50-100HZ Adjustable Frequency: The motor supports smooth speed adjustment within the 50-100HZ range, allowing precise control over connected equipment (e.g., adjusting conveyor speed for different product sizes, or modifying pump flow rates). This flexibility eliminates the need for additional speed reducers, simplifying system design.
High Starting Torque: With a starting torque of 1.8 times the rated torque, the motor can handle heavy loads during startup (e.g., mining crushers, large lathes) without stalling. This reduces mechanical stress on both the motor and connected machinery.
TEFC Cooling Design: The totally enclosed fan-cooled structure isolates internal components from external dust, debris, and moisture while using a built-in fan to circulate air. This ensures the motor remains cool even during 8-hour continuous operation, keeping the temperature below 80℃ and preventing overheating.
IP55 Protection Rating: The motor meets the IP55 standard, meaning it is fully dustproof and protected against low-pressure water jets (e.g., accidental splashes in workshops). This makes it suitable for use in dusty mining sites, textile mills with high lint levels, and outdoor auxiliary equipment.
34KG Cast Iron Casing: The heavy-duty cast iron housing provides exceptional structural strength, resisting impact and vibration during operation. It also reduces operational noise to less than 70dB, creating a quieter working environment.
CSA Security Certification: The motor has passed rigorous testing by CSA (Canadian Standards Association), verifying its compliance with global safety standards for electrical insulation, temperature resistance, and mechanical stability.
B3T Mounting Design: The B3T horizontal mounting configuration is compatible with most industrial machinery, allowing for quick installation and alignment with shafts or belts. The mounting base features pre-drilled holes for secure fixation.
The YVF variable-frequency motor is widely used in high-load, speed-sensitive industrial scenarios:
Mining Equipment: Powers conveyors, crushers, and screening machines in mines, where adjustable speed is needed to handle varying ore sizes and prevent blockages.
Machine Tools: Drives lathes, milling machines, and grinding machines in manufacturing plants, enabling precise speed control for different materials (e.g., slower speeds for hard metals, faster speeds for plastics).
Textile Machinery: Operates weaving machines, spinning frames, and dyeing equipment in textile factories. Adjustable speed ensures consistent fabric quality (e.g., finer fabrics require slower weaving speeds).
Power & Water Infrastructure: Controls pump systems in power plants (for cooling water circulation) and water treatment facilities (for adjusting water flow rates based on demand), reducing energy waste during low-demand periods.
No. Strictly do not use non-variable-frequency power for this motor. The YVF series is designed exclusively for frequency converter input; using standard grid power (fixed 50/60HZ) will cause the motor to overheat, damage the winding, or even lead to motor burnout. Always ensure the frequency converter matches the motor’s rated parameters (4KW, 380V) before use.
Reliable grounding is a critical safety measure. The motor’s electrical components may generate leakage current during operation; proper grounding diverts this current to the earth, preventing electric shock risks for operators. Additionally, the terminal box screws must be tightly fastened (as specified in safety warnings) to avoid loose connections that could cause arcing or short circuits.
Fan Inspection: Every 3 months, check the cooling fan for debris (e.g., dust, lint) that may block airflow. Clean the fan and fan cowl with compressed air or a soft brush.
Fan Cowl Integrity: Ensure the fan cowl is not cracked or damaged, as this could allow dust to enter the motor and reduce cooling efficiency. Replace the cowl immediately if any damage is found.
Bearing Lubrication: Lubricate the fan’s bearings annually with high-temperature grease to maintain smooth operation.
