24V DC Cooling Fan oil-bearing characteristics

Conventional DC brush less "24V DC Cooling Fan" motor design, the blades of the rotor (referred to as the rotor) and the axis of the core through the oil-bearing, short SLEEVE bearings, pivot motor fixed at the center of the star, the rotor and star maintain a proper gap between, of course, "24V DC Cooling Fan" between the shaft and bearing are also sure of the existence of a gap, it will not be the axis of the core deadlock and can not operate; motor star structure part of (the star), after the power input, it will generate induced magnetic field lines, and control of the drive circuit between the rotor and the star of the fan motor running. Therefore tradition "24V DC Cooling Fan" motor structure, only one fan rotor and a star and a motor drive circuit, and through the shaft and the pivot bearing of access, with the magnetic field induction and running,
