Which is the vibration motor of eye massager good-- Shunchang motor

Vibration Motor can be used in silicone rubber face washing instrument, massager, gender products, acoustic electric toothbrush and mobile phone. As long as the electronic equipment that must vibrate the actual effect, small vibration motor will be used. So how does the vibration motor complete the actual effect of vibration? We know that the Small Dc Motor operates according to the mechanical kinetic energy caused by electromagnetic energy (mentioned in detail in the article above), but this kind of operation can only rotate the whole process and can not cause vibration. At this time, we must install a rack on the shaft of the small motor. When the small motor runs, the simple harmonic motion of the center point of the rack has no rotating center of the motor, so the small motor will continue to be in an unbalanced situation, and the vibration is caused by the effect of inertial force. The higher the speed ratio, the greater the vibration frequency.

Vibrating motors can also choose different racks according to different main purposes

For the application of small vibration motor, it must be noted that if it is a small motor used to vibrate on the mobile phone, the rated current of the design scheme shall be close to the working standard voltage of the power circuit on the mobile phone as far as possible. That can improve the comprehensive performance of small motors; If the load output voltage of small vibration motor is greatly reduced, it may endanger the vibration compressive strength. Therefore, the module shall be designed with small characteristic impedance as the specification; When installing the motor, the gap shall not be large, otherwise it will cause vibration and noise. It can be fixed with a plastic sleeve to prevent it, but it shall not endanger the vibration output of the small motor, otherwise the vibration will be reduced.
