Youdaoplaceholder0 High energy efficiency and power factor ‌

Youdaoplaceholder0 Permanent magnet synchronous motor ‌ stands out particularly: 2%-8% more efficient than conventional asynchronous motor, and maintain high efficiency within the load range of 25%-120%; There is no reactive excitation current loss during operation, and the power factor is significantly improved.

It adopts a low-speed and high-torque design. The direct drive system can replace the traditional mechanical reduction device, reducing the volume by more than 50%.

Youdaoplaceholder0 Compact and lightweight ‌

Permanent magnet motors achieve smaller volume and weight by optimizing the magnetic circuit design. For instance, direct drive systems do not require reducers or pulleys, significantly reducing the installation space. Vibrating motor ‌ (vibrating motor) and other special types have the characteristics of light weight and adjustable excitation force, suitable for precision control scenarios.

Youdaoplaceholder0 Stable operation and low noise ‌

Permanent magnet synchronous motors eliminate mechanical reduction devices, reduce the noise of gear or belt transmission, and operate more smoothly. Asynchronous starting permanent magnet motors improve starting performance through cage-type windings, but attention should be paid to the problems of noise and vibration control.

Youdaoplaceholder0 Material dependence and cost fluctuations ‌

Permanent magnet motors rely on rare earth materials and have the risk of demagnetization (under high temperature, vibration or overload), and their manufacturing costs are greatly affected by the prices of raw materials.

Multi-functional application scenarios

Permanent magnet motors can be used as both electric motors (such as for driving electric vehicles) and generators, but they need to be combined with frequency converters to achieve speed regulation and stable operation. The DC brushless motor (DC brushless motor) is controlled by a variable-frequency power supply and features both high efficiency and maintenance-free advantages.
