During the working process of the asynchronous conventional motor, if there is vibration, it will not only affect the normal use of the equipment, but also leave a safety hazard. So, why does it vibrate? Next, let's explore the vibration generated by it. What are the reasons and how to troubleshoot these 2 problems.
First, the cause of vibration
1. Unbalanced rotor: In the manufacturing process of the motor rotor, if the mass distribution is unbalanced, or there is a deviation between the rotor and the axis, an unbalanced force will be generated during the working process, which will cause vibration.
2. Motor support problem: If there is a problem with the support structure of the motor, such as uneven installation, loose fixation, etc., it will cause the motor to shake and vibrate during rotation.
3. Wear of motor parts: During the long-term use of the motor, the parts tend to wear or loosen, which will also become one of the reasons for the vibration of the motor.
4. The counterweight of the motor is unbalanced: If the counterweight inside the motor is unbalanced, the center of gravity of the rotor will shift, which will cause vibration.
5. Problems with the working environment of the motor: If the environment in which the motor is located is relatively harsh, for example, the temperature is too high or too low, the humidity is too high, etc., it may cause poor heat dissipation of the motor, thereby hindering normal operation.
2, Overhaul method
1. Meticulous maintenance. During the use of asynchronous conventional motors, it is very necessary to develop good maintenance habits. You can regularly clean the motor casing and check whether each component is loose or worn, which can effectively prolong the life of the motor. The service life of the motor.
2. Correct installation and positioning. During the installation process of the motor, the operation must be strictly in accordance with the requirements of the motor manufacturer to ensure that the motor can run stably. In addition, it is also necessary to choose a reliable motor support structure to ensure that the motor can withstand force Uniform, high assembly precision, so as to prevent motor vibration.
3. Appropriate counterweight. If it is found that the motor has an unbalanced counterweight, it needs to be re-countered to restore the balance of the rotor.
4. Replace the parts of the motor. If the motor has a long life, the aging and wear of specific parts need to be replaced in time. In the process of replacing parts, the compatibility of old and new parts must be ensured And uniformity, so that the normal use of the motor can be guaranteed.
In short, in order to avoid the vibration of asynchronous conventional motors, it is necessary to control the use, maintenance, and repair of the motor. I believe that as long as we strengthen the maintenance and maintenance of the motor and try our best to pay attention to details in daily use, we will be able to effectively reduce the vibration of the motor. Vibration occurs to ensure the normal operation of the equipment.
