The type of cooling fan

Cooling fans are divided into two categories and DC and AC

working principle:

A) DC cooling fan is the use of direct current to provide power: DC motor stator and rotor composed of two parts, the stator has a magnetic pole (winding or permanent magnet), the rotor has a winding, power, the rotor also formed a magnetic field Magnetic pole), there is an angle between the stator and the pole of the rotor, and the motor rotates under the mutual attraction of the fixed rotor magnetic field (between the N pole and the S pole). Changing the position of the brush can change the stator and rotor clamp (Assuming that the direction of the magnetic pole of the rotor is the direction of the direction of rotation of the motor), and the direction of rotation of the motor is changed.
B) AC cooling fan is to use alternating power to provide power: single-phase AC motor only one winding, the rotor is squirrel-cage. When the single-phase sinusoidal current through the stator winding, the motor will produce an alternating magnetic field, this The strength and direction of the magnetic field changes sinusoidal time with time, but it is fixed in the spatial orientation, so the magnetic field is also called the alternating pulsating magnetic field. The alternating pulsating magnetic field can be decomposed into two at the same speed, For the opposite rotation of the magnetic field in the rotor to produce two equal size, the opposite direction of the torque, making the synthetic torque is zero, so the motor can not rotate when we use the external force to the motor in a direction of rotation (such as clockwise Rotation), the movement of the cutting magnetic field between the rotor and the rotating magnetic field in the clockwise rotation direction becomes smaller; the movement of the cutting magnetic field between the rotor and the rotating magnetic field in the counterclockwise rotation direction becomes larger, so that the balance is broken and the total The electromagnetic torque will no longer be zero and the rotor will rotate in the direction of the push.

Axial fan, that is, with the fan in the same direction as the air flow, such as electric fans, air conditioning fan is the axial flow mode fan. The reason known as the 'axial flow' is because the gas parallel to the fan shaft flow. The flow fan is usually used in applications where the flow rate is high and the pressure is low, and the axial fan is fixed and the air is moved.
