Recently, the editor noticed that there has been an increase in the global polishing machine failure rate, especially in electrical component failures, according to customer feedback. Among them, the failure rate of motor burnout is the most common. What is the reason for this, or is the quality problem of the motor itself caused by improper use due to some human factors?
After consulting with repair workers from other places and analyzing the on-site images, it was found that the majority of motor burns were caused by improper use or external factors.
Maintenance of polishing machine motor
Voltage issue: Since July, high temperatures have spread throughout the southern regions, leading to severe electricity consumption. In some places, voltage instability and tripping often occur. Especially some small processing plants are transformed from residential buildings. In order to save money, these customers are often unwilling to renovate the entire line. When the polishing machine is formed, the voltage is insufficient, and the motor power is insufficient when the equipment is started. The pressing requirement for polishing leads to an instantaneous increase in current and motor temperature. Over time, the motor will burn out.
Overloaded work: In order to achieve the highest production power, the customer works two shifts 24 hours a day, and the polishing machine motor drive is overloaded for a long time, without effective maintenance and repair. The stator current greatly exceeds the rated current, causing the motor to overheat. This exacerbates the risk of motor burnout.
Environment and ventilation heat dissipation: Many customers do not install corresponding ventilation and vacuum equipment in order to save costs. The polishing machine dust generated during polishing cannot be effectively cleaned. Long term sedimentation completely blocked the motor's heat dissipation holes. Make it impossible to dissipate the working heat of the motor. Long term high-temperature operation of the motor can also cause it to burn out.
The above points are one of the serious factors that cause the polishing machine motor to burn out. In order to ensure safe and stable production. Dear customer, please take good care of your equipment, regularly inspect and maintain it. Ensure that the equipment maintains optimal working condition for a long time.
