48v Fan

Brushless DC fan is brushless at first, brushless corresponding to brush speaking, that is, when the fan is running, the commutation does not use carbon brush contact commutation, just with the help of electronic parts commutation.

Electronic commutation, electronic commutation is the use of Hall devices to test rotor magnetic polarity commutation, phase conversion is electronic parts commutation, so no carbon brush commutation mechanical contact caused by electromagnetic sparks. Therefore, the brushless fan has the disadvantage of short mechanical life due to sliding friction caused by mechanical touch commutation method without electromagnetic radiation interference and carbon brushless commutation method.
Brushless DC fans are initially brushless, brushless corresponds to brushless speaking, that is, when the fan is running, reversing does not use carbon brush contact reversing, only reversing with the help of electronic components.

Electronic reversal, electronic reversal is the use of Hall devices to test rotor magnetic polarity reversal, phase conversion is the reversal of electronic parts, so no carbon brush reversing mechanical contact caused by electromagnetic sparks. Therefore, brushless fans have the disadvantage of short mechanical life due to the mechanical contact reversing method without electromagnetic radiation interference and the sliding friction caused by the carbon brushless reversing method.
