Why asynchronous motors save energy compared to DC motors

Why asynchronous motors save energy compared to DC motors

Summary of energy-saving suggestions for asynchronous motors and DC motors: prioritize asynchronous motors: if high power, variable load, high efficiency and energy saving are required (such as fans and pumps), asynchronous motors with variable frequency speed regulation are better. Choose a DC motor: If high torque, constant speed operation, and stable load are required (such as for CNC equipment), a DC motor is more suitable. Improvement of frequency conversion technology: Asynchronous motors can significantly save energy through frequency conversion speed regulation, but attention should be paid to load matching to avoid efficiency decline.

Why is asynchronous motor called asynchronous

Why is asynchronous motor called asynchronous

The reason why asynchronous motors are called "asynchronous" is mainly due to the inherent difference between their speed and power frequency. The following are specific reasons: asynchronous speed and frequency, electromagnetic induction drive mechanism, differences in structure and operating principle. In summary, the "asynchronous" characteristics of asynchronous motors are reflected not only in the inherent differences in speed and frequency, but also in their electromagnetic induction drive mechanism and structural design.
