Buy a hair dryer motor, the principle of the hair dryer is actually very simple, the main use is a small fan inside the hair dryer and a section of electric heating wire structure. Hair dryer is generally can be divided into hot air and cold air, hot air needs electric heating wire to generate a lot of heat, electric fan operation will blow out the heat, you can feel the hot air at the time of use. If you just want cold air, then you only need to let the small fan run, electric heating wire is not on the electricity, so the hair dryer in the process of running will not produce heat, this time feel is cold air. So the main use of the hair dryer is this small fan device. When the hair dryer is energized, it can make the motor inside the hair dryer to start running.
Electric energy into kinetic energy, can drive the rotation of the fan blade, when the fan blade in the hair dryer fast rotation, can make the air fast rotation. The air outlet of the hair dryer is a long and thin cylinder, so it will form a centrifugal air flow, so the air flow generated inside the hair dryer can be blown out from the inside of the air duct.
