Motor market development trend
As energy conservation becomes the focus of global attention, the energy efficiency of motor design has increasingly become an issue of concern. Motor drive products continue to cooperate with the development trend of the industry, helping designers to improve energy efficiency, reduce energy consumption, improve reliability, reduce component count, etc., and play an active role in achieving energy conservation.
Motor market development trend
After a hundred years of development, the application field of electric motors has been very extensive. The application of motor drive products in the automotive and industrial fields is a microcosm of the main trend in the motor market.
The first is the trend of automotive electrification, in which automotive manufacturers integrate high-efficiency motors to replace traditional internal combustion engine power, usually with brushless direct current (BLDC) motors instead of belts and gear drives, for auxiliary components under the hood, such as pumps, Valves, heating and air conditioning, fans, etc. Due to the excellent performance of BLDC motors, other applications that traditionally use brushed DC (BDC) motor solutions have begun.
Another trend is that the increase in application assembly rate has increased the number of motor installations, such as motorized heating, ventilation, and air conditioning (HVAC) air flap control (mainly used for brushed DC and unipolar stepper motors). HVAC system.
The application of BLDC motors in industrial and telecommunications is also becoming more and more common. Typical applications include fans, blowers, pumps, and compressors. BLDC motors are more energy efficient than AC motors or switched reluctance motors. BLDC motors enable low-cost variable speed applications, especially for integrating sensorless commutation algorithms, eliminating the need for external sensors.
