Nail Polisher Micro Motor Noise Too Much Solution

The main function of the nail polisher comes from the micro DC motor drive to drive the grinding head, so the micro motor in the nail polisher is very important, but some users in the use of the polisher will encounter the problem of excessive motor noise, affecting the use of experience, so what are the ways to solve the nail polisher micro motor noise method? Today we will introduce to you, hope it will help you!

The easiest way to reduce the noise of a micromotor is to apply lubricant to its bearings. You can also use precious metal brushes to reduce noise, but they have a shorter lifespan than carbon brushes.
In addition to the above methods, you can also wrap a layer of acoustic foam around the micromotor in the nail polisher assembly. This can be successful in minimizing the noise, which can usually be kept between 40 and 50 decibels.
In addition to this, a brushless motor is also an option, as it uses an electronic commutation device that eliminates friction between the carbon brushes and commutator, reducing noise. However, brushless motors are nearly 1.5 to 2 times more expensive than brushed DC motors, which increases the price of nail polishers. In addition, the control method of brushless DC motors is more complex than that of carbon brush motors, which is another important disadvantage.

The above is the solution to the excessive noise of the nail polisher micro motor, I hope it will help you, for more information about it, please feel free to consult us!
