Professional manufacturing and production of radiator cooling fans, condenser fans and fan motors, etc.

What is the method of cooling fan control adjustment speed?

Cooling fan control adjusting speed method has the following three, small make up the following introduction could help you.


1, the speed control of dc cooling fan is mainly rely on improve coil current, can also increase the voltage to speed up. But it's easy to burning motor.


2, the use of dc speed control to adjust speed.


3, dc torque motor based on fuzzy PID speed control.


in the analysis of fuzzy control and PID control, on the basis of combination way, design a two-dimensional fuzzy PID control algorithm, the algorithm meets the threshold according to the error signal to decide when to switch between fuzzy control and PID control. The encoder, 80196 kc singlechip, 16 bits D/A converters and dc torque electric and combined with the above constitute dc torque motor of the fuzzy PID control algorithm steady speed control system.


based on the standard of PID and fuzzy PID measured data analysis and comparison
