What are the types of motors for cooling fans
Aug 22 , 2024
1. Brushless DC Motor (BLDC) Advantages: The brushless design reduces energy loss and improves overall efficiency. Because there is no brush, the brushless motor has less wear and longer life. Smooth operation and low noise for applications requiring a quiet environment. Disadvantage：High cost, the manufacturing process is complex, and the cost is higher than that of brushed motors. Complex contro...

What is gridlock feedback technology?
Feb 17 , 2025
The cooling fan with gridlock feedback technology refers to a technology used to prevent the fan motor from gridlock (that is, the motor shaft is stuck or unable to rotate) during operation. It monitors the speed and current of the motor in real time to determine whether there is a lock-up, and when it detects a lock-up, it feeds back to the control system to start the protection mechanism or take...
