采用永磁直驱的方式，与使用变速箱/皮带轮等驱动方式相比，具有高效节能、控制精度高控制性能好、启动转矩大、电流小、运行平稳等优点，与变频器匹配使用，能给客户带来更加智能的使用体验，提高便利性，有效降低维护成本。
Adopting the permanent magnet direct drive method, compared with the drive methods such as using gearboxes or pulleys, it has the advantages of high efficiency and energy saving, high control accura- cy and good control performance, large starting torque, small current, and smooth operation. When used in conjunction with frequency converters, it can bring customers a more intelligent usage experi- ence, improve convenience, and effectively reduce maintenance costs.
工作效率高 High work efficiency
永磁同步电机体积小、重量轻、工作效率高(一级能效)，而异步电机工作效率只有 (85-89)%之间;
Permanent magnet synchronous motors are small in size, light in weight and have high working efficiency (first-class energy efficiency), while the working efficiency of asynchronous motors is only between 85% and 89%.
传动效率高 High transmission efficiency
永磁同步电机因设计启动转矩大， 能够满足低转速运行， 从而取代了变速箱或皮带传动装置;改为电机与风机直连，没有了其他传动部件的效率上的损失，整体传动效率提高15%左右;
Permanent magnet synchronous motors, due to their large design starting torque, can meet the requirements of low-speed operation, thus replacing gearboxes or belt drive devices. It was changed to direct connection between the motor and the fan, eliminating the efficiency loss of other transmission components, and the overall transmission efficiency was increased by about 15%.
永磁同步电机与变频器配合，将启动方式改为软启动，能明显降低用其他启动方式所产生的噪音(15dB左右)。
直连配合 Direct connection coordination
永磁同步电机与风扇采用直连的安装方式，没有了原来的皮带传动或齿轮箱传动所产生的噪音，有效的降低了运行中的噪音(6dB噪音)。
The permanent magnet synchronous motor and the fan are installed in a direct connection, eliminating the noise generated by the original belt drive or gearbox drive, effectively reducing the noise during operation (6dB noise).
永磁同步电机因转速较低，在设计时取消了风冷散热装置，而异步电机是靠风扇散热的，因此电机运行时能降低噪音(10dB)左右。
Permanent magnet synchronous motors, due to their lower rotational speed, do not have air-cooling heat dissipation devices in their design. In contrast, asynchronous motors rely on fans for heat dissipation. Therefore, the noise during motor operation can be reduced by approximately 10dB.
