In terms of the nail drill, users only need to polish lightly the fingertips with it, and there is no need to use nail removers containing chemical ingredients to remove nails. It can be easily used at home or in beauty salons. The main function of beauty supply nail drill is credited to a micro DC motor which can drive the polishing head, so the micro motor is very important.

During the application process, some micro motors are very noisy, which is very bad for the user experience. How to solve the problem of excessive noise of the nail drill micro motor? Let's briefly explain it below.

How to solve the problem of high noise from the beauty supply nail drill?

Most of the micro motors used in the common nail drills on the market are carbon brush motors, which have the characteristics of simple speed control and low cost.

However, during the rotation of the micro motor, the carbon brushes and the commutator will constantly rub against, which will generate a certain amount of noise. The faster the speed of the beauty supply nail drill, the greater the noise.

Generally, if the speed of the micro motor for nail drills is at 20000 to 30000rpm the noise will be relatively large, so the micro motor needs to be processed to reduce the noise.

The simplest way is to apply lubricating grease to the bearing of the micro motor of portable professional nail drill, which can effectively reduce the noise of the micro motor, but there will still be noise. Although the noise pollution will not greatly influence the using experience, it still needs improvement.

The micro motor of portable professional nail drill made by JIMDOA adopts the method of applying imported electric brush oil to reduce the noise, reducing the friction between the carbon brush and the commutator, making the noise lower, and you can also use the precious metal brush to lower the noise. But the service life is not as long as that of carbon brushes.

In addition to the above methods, when assembling the micro motor for the nail drill, you can wrap a layer of soundproof cotton on the micro motor of the beauty supply nail drill, and finally the noise can be greatly reduced. Generally, it can be controlled at about 40dB to 50dB.

Of course, a brushless motor can also be used, because it uses an electronic commutation device, and there is no friction between the carbon brush and the commutator, and thus the noise will be lower.

However, the cost of brushless motors is almost 1.5 to 2 times that of brush motors, so it will increase the cost of beauty supply nail drill, and the control method is more complicated than carbon brush motors. This is also a major disadvantage of brushless DC motors.

Therefore, there are still a lot of nail drills that use brushed DC motors on the market, and brushed DC motors only need to be processed for noise isolation.

The above is the solution to the excessive noise of micro motor of the beauty supply nail drill. For more information about the beauty supply nail drill, please continue to pay attention to JIMDOA professional rechargeable electric nail drill.
