1. The scope of application of brushless DC cooling fans: usually used in equipment with relatively high control requirements and high speed, such as airplanes, precision instruments, etc., which have strict motor speed control and high speed. 2. The service life of the brushless DC cooling fan: The service life is usually in the order of tens of thousands of hours, but the service life of the brushless motor is also very different due to the different bearings. For example, the life of oil-impregnated bearings is generally 20,000 hours, and double ball bearings are generally 50,000 hours.
