  • How much more energy-efficient is the new permanent magnet synchronous motor-driven drum than the traditional motor? 22/09

    2025
    How much more energy-efficient is the new permanent magnet synchronous motor-driven drum than the traditional motor?
    Introduction In modern industrial systems, motor energy consumption often accounts for the majority of electricity used in production. Data shows that over 60% of electricity consumed in the manufacturing industry is consumed by motor equipment. With energy prices continuing to rise and the advancement of the "dual carbon" goals, improving motor efficiency has become a dual imperative for companies to reduce operating costs and achieve sustainable development. In recent years, permanent magnet synchronous motor (PMSM)-driven drums have gradually entered the market, demonstrating their potential to replace traditional asynchronous motors with their outstanding energy-saving and high-efficiency performance. This article will analyze the differences in the principles of permanent magnet synchronous motors and traditional asynchronous motors, and compare their energy efficiency under different operating conditions using case data. It will also explore various external and internal factors that influence energy savings. Comparison of the Principles of Permanent Magnet Synchronous Motors and Traditional Motors The operation of an asynchronous motor depends on the interaction between the rotating magnetic field generated by the stator and the induced current in the rotor. To maintain this energy exchange, the motor must consume a certain amount of reactive excitation current during operation. Although this current does not directly output effective power, it does cause additional losses. Therefore, under partial load conditions, the efficiency and power factor of asynchronous motors often drop significantly. In contrast, permanent magnet synchronous motors (PMSMs) have high-performance permanent magnets embedded in their rotors. Excitation is provided directly by the permanent magnets, requiring virtually no reactive current support, thus reducing copper and iron losses. Their power factor is typically close to unity, resulting in stable torque output and high efficiency across a wide load range. According to tests conducted by the Chinese Society for Electrical Engineering, the power factor of PMSMs generally exceeds 0.95, while that of conventional asynchronous motors is typically only between 0.80 and 0.85. This fundamental difference gives permanent magnet synchronous motors an inherent advantage in energy efficiency. Energy Savings Data and Case Studies In practical applications, permanent magnet synchronous motor-driven rollers have achieved significant energy savings in logistics, metallurgy, textiles, and mining transportation. Light Load Conditions (20%–50% of rated load) PMSMs perform most effectively under low-load operation, reducing energy consumption by 30%–50%. In contrast, asynchronous motors experience a sharp decline in efficiency under light loads due to their low power factor and increased excitation losses. For example, at a logistics warehouse in Shanghai, replacing its drums with permanent magnet synchronous motors reduced electri...
