The causes of vibration faults in the motor are:
(1) The ground on which the motor is installed is not flat;
(2) The internal rotor of the motor is unstable;
(3) The pulley or coupling is unbalanced;
(4) The inner rotor is bent;
(5) Motor fan issues.
To resolve these issues, the first step is to ensure a stable base for the motor installation to maintain balance. In cases where the rotor is unstable, it should be checked and balanced. For unbalanced pulleys or couplings, they need to be properly adjusted or replaced. If the rotor is bent, it should be straightened or replaced. Lastly, if the motor fan is causing noise or imbalance, it should be inspected and repaired or replaced as necessary.
Piezoelectric Buzzer For Driver Circuit Built-in
The piezoelectric buzzers (for Driver Circuit Built-in) offer optimal sound, performance, and efficiency for all types of medical and industrial applications. Our piezo buzzers are constructed in a variety of sizes and work across varying frequencies which allows them to produce different sounds and tones. As voltage is applied to a piezo Buzzer, the piezoceramic disc vibrates, flexing with respect to input voltage to generate sound. Our piezo buzzers maintain low current draw which is advantageous for any battery operated device. Since piezo buzzers don`t have a magnet in their construction, it eliminates EMI/EMC issues.
