This section describes different speed adjustment modes of the heat dissipation fan
Dec 02 , 2024
Different types of speed regulation 1.Voltage speed regulation: By changing the input voltage to adjust the fan speed, mainly used in DC cooling fans. Although the cost is low, the accuracy and stability are slightly lower than that of current speed regulation. 2.PWM speed regulation: The use of pulse width modulation (PWM) signal to change the working period of the motor is currently the most wid...

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...
