Cooling fanAccording to changes in the application environment, the fans used can be divided into DC DC cooling fans and AC AC cooling fans according to voltage. The EC cooling fans derived from the back are now widely used. Cooling fans are used in electronic power and military equipment.
, home appliances, machinery and equipment and other industries have applications. Let's learn about the structure of industrial cooling fan DC/AC, DC and AC cooling fan!
DC DC cooling fan structure industrial cooling fan fan is divided into two parts: stator and rotor;
Rotor (roter): including fan blade (impeller), axis (axial), magnetic ring (magnet), magnetic ring outer frame (case) and oil ring;Stator (stator): including motor (motor), frame (frame), bearing (bearing), retaining ring (fasterner), spring (spring), upper cover (top cover), silicon steel sheet (sl steel), lower cover (bottom)cover）、电路板（PWM assembly）。
The winding part of the motor: composed of silicon steel sheet, enameled wire and upper and lower insulating wire frames.
The function of the silicon steel sheet is to export the magnetic poles to determine the strength of the north and south poles: the windings determine the directionality of the magnetic lines of force and push the magnetic frame to operate. The windings of the stator are mostly distributed symmetrically in four phases, forming an angle of 90 degrees with each other.
The structure of the AC AC cooling fan is also divided into two parts: the stator and the rotor:
Stator: including motor, outer frame, bearing, buckle, spring, silicon steel sheet.
Rotor: including fan blade and shaft center.
The winding part of the motor: composed of silicon steel sheet, enameled wire and insulating wire frame.
The single-phase internal structure of the stator winding is composed of two coils, one is the starting winding and the other is the running winding. The two windings are connected in series to each other, thus forming three points.
The above is the sharing of knowledge of the classification of the cooling fan structure.
