The main products as the following list, brushless DC cooling fan, AC heat dissipation fan, customized fans for special industries and so on.
Classification and structure of DC brushless cooling fans
Structure of DC brushless fan: It can be divided into four main parts: rotor, stator, frame, motor (motor) and some other components.
DC brushless fan structure: mainly divided into rotor, stato
The authoritative expert of the cooling fan knows that if we disassemble the motor of the DC cooling fan, we can see that the DC cooling fan is a variable frequency motor, which can be identified from the position of the electromagnetic coil.
The principle of the cooling fan
AC cooling fan design principle: the distinction between AC fan and DC fan fan.
Expectation of MTTF and L10 calculation 1. Product life expectancy MTTF refers to the expected time when the product is 63.2% bad.
What issues should be paid attention to when selecting the c
First, the air volume of heat dissipation, the wind pressure should be large enough, even if the noise is a little bigger, the fundamental heat must be lifted. We said above, the high temperature of the mining machine will be a problem.
Difference between AC, DC, and EC fans
Speaking of the cooling fan, it is estimated that everyone is very familiar with it, we can't lack it in our lives, household appliances, electronic products, digital computers, etc.
