Brushless DC Motor (BLDC) - Market Trend of Future Motors

2022-06-30 17:18:16 Volcano Motor Read

Brushless DC motor (BLDC) has too many advantages, no wonder it will become the market trend of future motors


Brushless DC motors (BLDC) are more expensive than brushed motors, but have obvious advantages, such as high performance and long life.


The motor market is dominated by the widespread use of AC motors and brushed DC motors, which is being broken by the situation of brushless DC motors.


When it comes to the convenience brought by the motor, we know that the brushless DC motor not only solves the problem of low efficiency of the traditional motor, but also brings us a lot of convenience. The moving distance is increased, and the distance between people is shortened. Another example is the cleaning robot, which is convenient for many office workers who do not have time to clean their homes.


Analyzing the advantages of BLDC, BLDC has higher efficiency than AC asynchronous motor, large torque, small torque ripple and long life.


Efficiency is an important indicator. Compared with traditional motors, BLDC motors have a BLDC efficiency of more than 80%, while the carbon brushes of current brushed motors require maintenance.


At present, the cost of brushed motors is low and the technical threshold is also low, so they have been promoted on a large scale. This also shows from the side that the potential demand for brushless motors with performance advantages has not yet been


Fully released, I believe that today's customers are getting more and more high-quality products, and BLDC still has ample room for development in the future. It is precisely because of the wide application of brushless DC motors that the corresponding control technology is required to be mature and reliable, and at the same time, it is also required that the control technology can improve performance and efficiency and have high cost performance. trend.


The miniaturization, integration and drive integration of low-voltage DC brushless motors will be the future market trends, especially in some enterprises that have higher requirements on production efficiency, small brushless integrated motors are also used to replace stepper motors and brushed motors. will be a big trend.
