How many volts is the motor of a hair dryer? How many volts of electricity are used in the motor in

According to the requirements of customers, motor manufacturers generally have DC18V, 24V, 28V, and 36V for general households, and AC110V and 220V for professional use, but because of household hair dryers.

The design of its motor is not directly connected to the 220V power supply, but between the motor and the power supply to add a section of heating electric furnace wire or the whole section of resistance wire in series with the motor in series, the length of the electric furnace wire and the size of the resistance are different due to different brands and power, and the voltage at both ends of the motor is different.

There are two types of motors used in hair dryers: AC induction motors and series-excited AC-DC motors.

The speed of the AC induction motor is also different according to the polarity: the speed of the two poles is 2960 rpm, and the speed of the four poles is 1480 rpm.

The speed of the series-excited AC-DC dual-purpose motor is generally 5000-12000 rpm according to the selected working voltage.

Generally, the motor of the hair dryer is a DC motor.

Divide positive and negative. Normal with four diodes.

It is IN4007, which plays a full-wave rectification role to turn alternating current.

Becomes direct current.

Generally, the step-down of the motor uses a thin resistance wire (R1). The main heating resistance of the duct is coarse (R2) The original connection method is: R1 is connected in series with the motor, and then at the same time with R2 at both ends of the power supply, and the air volume is adjusted with a diode half-wave rectification.

Switch control half-wave or full-wave input If the motor string has resistance, the hair dryer is only strong heat and weak heat two gears, if there is a cold gear, the motor should be micro AC220V, AC motor is no resistance.

Because of the design of household hair dryer, its motor is not directly connected to the 220V power supply, the surface is between the motor and the power supply to add a section of heating electric furnace wire or the entire section of resistance wire is connected to the motor in series, the length of the electric furnace wire and the size of the resistance are different due to different brands and powers, and the voltage at both ends of the motor is different.

Generally, there are DC18V, 24V, and 36V for household use. There is also a professional AC220V.

Summary. Hello, how much V electricity is used in the hair dryer you have consulted The answer is that the 220V voltage of the hair dryer is not wrong, but the electricity used by the motor in the hair dryer is rectified direct current, and the voltage varies from 12 to 36V, in fact, the 220V voltage is directly supplied to the heating wire, but the voltage reduction on the heating wire is rectified to DC before it is supplied to the motor.

Hello, how much V electricity is used in the motor in the hair dryer you consulted The answer is that the 220V voltage of the hair dryer is not wrong, but the electricity used in the motor in the hair dryer is rectified DC electricity, and the voltage is 12 36V, in fact, the 220V voltage is directly supplied to the heating wire, but the voltage of Huizhou is reduced by the tap on the heating wire and becomes DC after rectification before it is supplied to the motor.

Hello brother Sheng, the above is the answer given, if my answer is helpful to you, I hope you can give me a five praise to support it, your praise is the most hidden stool for me to move forward, thank you very much for your support, I wish you a happy life

The voltage used in the small DC motor of the hair dryer is generally about 6V, and the power does not exceed 2W; The voltage of the small AC shaded pole motor is AC 220V, the power is generally 5 8W, the DC motor is used as a hair dryer for blowing wind and leaking power, because the motor brush is easy to wear, it is not suitable for long-term operation, and is only suitable for use in the front of the house. This kind of hair dryer is light in weight, low in weight, and has a very large variety and quantity, and is the most common product.

Hair dryer is generally divided into professional and household two, professional hair dryer generally uses AC (AC) motor, the domestic use of AC motor working fiber rotten voltage is 220V household hair dryer generally used DC motor (DC), is the hand feels very light and very small kind, this kind of motor is now used in China are rated, so directly with 220V when it will use step-down heating wire voltage reduction and use diodes or rectifier bridge stack

The pre-liquid power of hair dryers is generally between 600 and 2000 watts, and most hair salons are 2000 watts. If you sell it at home, you can choose 600 to 1300 watts, the power of the hair dryer is related to the internal heating wire, the greater the power, the thicker the heating wire, the more heat energy is produced, in addition, if you use a high-power hair dryer for a long time, the hair will dry out, and the scalp will be damaged.

The power of the hair dryer is not as large as possible, the power should be selected according to the actual situation, too big is not only the most expensive, but also more energy-consuming, and the greater the amount of radiation it produces. In order to be able to dry their hair in a short time, many people often buy high-power hair dryers, although they can dry their hair quickly, but its radiation is also very large.

Precautions for buying a hair dryer: 1. Before buying, you must figure out your own hair quality, if it is dry hair, then do not equip the type of wind that is too strong, there are many categories of hair dryers on the market now, which is very popular with people, it can protect the hair and scalp, because it can automatically sense the temperature of the hair, and the hair can be automatically adjusted after drying, so as to retain the moisture on the head so that it will not become dry.

2. From a functional point of view, the hair will be affected by static electricity in winter, and it will be unkempt and frizzy, so it is necessary to ensure the maintenance ability of the hair dryer when purchasing.

For home use, you can generally choose a hair dryer of about 600 watts to 800 watts, which is more suitable. The barber shop recommends about 2000w.

Generally, the power of the hair dryer is mainly related to the heating wire of the hair dryer, the greater the power, the thicker the heating wire, and the more heat energy it generates, so the radiation is also relatively large. The general household hair dryer chooses 22V power, and the common hair dryer power mainly includes: 250 watts, 350 watts, 450 watts, 550 watts, 850 watts, 1000 watts, 1200 watts.

Many hair dryers are more noisy when they are used, so it is easier to affect themselves and others, usually the better quality hair dryer products are generally less noisy when using it, you should turn on the hair dryer first when you buy it, and see if the noise of the hair dryer is big.
