Cooling fan type

Cooling fan can be divided into two categories, and DC and AC

Working principle

1: DC thermal fan is using DC electric for its provides power: DC motor has stator and rotor two big part composition, stator Shang has pole (winding type or PM type), rotor has winding, power Hou, rotor Shang also formed magnetic field (pole), stator and rotor of pole Zhijian has a angle, in set rotor magnetic field (n very and s very Zhijian) of mutual attract Xia, is motor rotating. Change the seat of the brush, you can change the angle between the stator and rotor magnetic pole (assuming the stator magnetic angle start, the magnetic side of the rotor, stator of a rotor pole pointing to the direction of the magnetic pole is the direction of rotation of the motor), thus changing the direction of rotation of the motor.
2: AC cooling fan is alternating electric provides power supply: single-phase AC motor is only one winding, the rotor is cage. When you single phase stator winding of the sinusoidal current through the motor generates an alternating magnetic field, the strength of the magnetic field and the direction of time sinusoidally, but is fixed in space, also called the magnetic field oscillating pulsating magnetic field. This alternating pulse magnetic field can be decomposed into two with the same speed, rotate opposite each other in the direction of a rotating magnetic field. Produced in the rotor are two equal and opposite torque, makes the synthesis of the torque is zero, so the motor cannot rotate. When we use external forces caused the motor to rotate in one direction (clockwise), and rotor and rotating clockwise rotating magnetic field in the direction of cut magnetic lines of force movement between smaller; Rotor with counterclockwise rotation of the rotating magnetic field in the direction of cut magnetic lines of force movement gets bigger. This balance is broken, generated by the rotor of the total electromagnetic torque is not zero, the rotor will rotate along the driving direction.

Axial fans, is the shaft with blade with the direction of the air flow, such as electric fans, running air conditioner outdoor unit fan is an axial flow fan. Is called ' Kaplan ' is because gas flows parallel to the fan shaft. Axial-flow fans are typically used in situations of low flow demands and pressure requirements. Fixed position of axial-flow fan and allows the air to move.
