In daily communication, customers usually don’t know whether to choose an industrial hvls fan with a reducer motor or a permanent magnet motor, and often need us to make recommendations. To recommend a suitable product, you need to first understand the advantages and disadvantages of the two motors. The following is a comprehensive comparison of RTFANS industrial hvls fan with reducer motor and fan with permanent magnet inner rotor motor:
1. Efficiency and energy consumption
• Industrial hvls fans with reducer motors:
o Advantages: Mature technology, suitable for high-power, low-speed applications, and the reducer can adjust the output speed.
o Disadvantages: Large mechanical transmission loss, low overall efficiency, and higher energy consumption compare to magnet motor.
• Fans with permanent magnet inner rotor motors:
o Advantages: Permanent magnet motors have high efficiency, low energy consumption, significant energy-saving effects, and are suitable for high-speed applications.
o Disadvantages: High initial cost.

2. Structure and maintenance
• Industrial hvls fans with reducer motors:
o Advantages: Simple structure, easy maintenance, mature reducer technology, and low maintenance costs.
o Disadvantages: The reducer requires regular maintenance (such as lubrication, gear replacement, etc.), which increases the maintenance workload. (RTFANS provide 20000 running hours’ free maintenance assurance)
• Fans with permanent magnet inner rotor motors:
o Advantages: compact structure, no mechanical transmission parts, low maintenance cost, and low failure rate.
o Disadvantages: Once the permanent magnet motor is damaged, it is difficult to repair and the entire motor may need to be replaced.

3. Noise level
• Fans with traditional reducer motors:
o Advantages: no significant advantages.
o Disadvantages: Mechanical noise is generated during the operation of the reducer, and the overall noise level is higher than magnet motor fan.
• Fans with permanent magnet inner rotor motors:
o Advantages: low noise during operation, providing a quieter working environment.(magnet noise is still there especially at certain frequency)
o Disadvantages: no significant disadvantages.

4. Adaptability and reliability
• Fans with traditional reducer motors:
o Advantages: mature technology, high reliability, suitable for harsh working conditions (such as high temperature, high humidity, and dusty environments).
o Disadvantages: The reducer may require more frequent maintenance in harsh environments.
• Fans with permanent magnet inner rotor motors:
o Advantages: Strong adaptability, suitable for a variety of working conditions, especially high speed and high efficiency demand scenarios.
o Disadvantages: Permanent magnet materials may demagnetize in high temperature environments, affecting performance.

5. Cost and cost performance
• Fans with traditional motors with reducers:
o Advantages: Low initial cost, suitable for customers with limited budgets.
o Disadvantages: Higher energy consumption in long-term operation, high maintenance cost, and average overall cost performance.
• Fans with permanent magnet inner rotor motors:
o Advantages: Low energy consumption in long-term operation, low maintenance cost, and high overall cost performance.
o Disadvantages: High initial cost and if motor damaged it cannot be repaired.
6. Technical features
• Fans with traditional motors with reducers:
o Advantages: Mature technology, wide market application, suitable for low speed and high torque scenarios.
o Disadvantages: Low mechanical transmission efficiency and slow response speed.
• Fans with permanent magnet inner rotor motors:
o Advantages: fast response speed, high control accuracy, suitable for high speed and high efficiency scenarios.
o Disadvantages: The technology is relatively new, and some customers may have doubts about its long-term reliability.
Summary:
“RTFANS industrial hvls fan with reducer motor has mature technology and is suitable for low-speed, high-torque scenarios, especially for spaces above 8 meters (up to 40 meters). The initial cost is low, but the long-term operating energy consumption and maintenance costs are higher than permanent magnet motor fans (RTFANS configuration can reach 20,000 hours maintenance-free). The RTFANS permanent magnet inner rotor motor has high efficiency, low energy consumption, low noise, and low maintenance cost. It is suitable for high-speed, high-efficiency demand scenarios and is recommended for 6-15 meters. Although the initial cost is high, the long-term cost-effectiveness is higher. According to your specific needs (such as working conditions, budget, efficiency requirements, etc.), we can recommend the most suitable fan solution for you.”
