The reasons for the strange noise of the automatic toroidal coil inductor winding machine and the judgment

Winding machine normal operation without noise, only large winding machine uniform “humming” fan sound and roar. If abnormal noise and low roar is heard during operation, it means the winding machine is malfunctioning and should be stopped immediately for maintenance.

When the winding machine foundation is not strong or fixed, if the rotor parts are loose, such as the weight screw on the fan blade or the rotor shaft is loose, the winding machine will make a knocking sound. The winding machine will also produce vibration and uneven friction sounds when the shaft is bent or worn. Insufficient bearing lubricant, the winding machine bearing room has a “hiss, hiss” sound. The steel balls in the bearings are damaged during operation with a “gurgling” sound. In addition, electrical faults can cause vibration and abnormal noise in the winding machine. If the current is too high, the three-phase current is clearly unbalanced, especially when the three-phase winding machine is in single phase. When the rotor breaks, the torque of the winding machine is reduced, the load current is unstable, a “buzzing” sound is made from time to time, and the machine body vibrates.
