company news about How to Tell if the Motor of My Dog Food Pellet Maker machine Is Bad?

Signal 1: Motor casing is electrified, posing a risk of electric shock.

This is a dangerous signal indicating motor damage and accompanying safety hazards, requiring immediate shutdown and power disconnection for inspection. Touch the motor casing with a test pen; if the test pen lights up, or the operator feels a tingling sensation upon contact, it indicates damage to the internal insulation layer of the motor and leakage in the windings, causing the casing to become electrified. Such situations often occur when the motor has been exposed to high temperatures and dust for extended periods, causing the insulation layer to age and break. Continued use will not only damage the motor but may also lead to electric shock. In this case, immediate stoppage is necessary to assess the extent of motor damage and, if necessary, replace the motor.

Signal 2: Motor trips during operation, frequently triggering the protection mechanism.

 Dog food pellet mill motors are equipped with overload and leakage protection devices. If the motor frequently trips during operation, and after ruling out abnormal circuit voltage and equipment jamming/overload issues, it is highly likely that the motor is internally damaged. Common causes include: short circuits in the windings leading to excessive current, triggering overload protection; damaged insulation causing leakage, triggering leakage protection; and seized motor bearings, leading to increased running resistance and a surge in current causing tripping. Frequent tripping will accelerate motor wear, requiring timely troubleshooting to prevent further damage.

Signal 3: Damaged motor bearings, exhibiting jamming or seizing.

Bearings are a core component of motor operation. Damaged bearings will directly affect the normal operation of the motor and may even lead to its complete failure. The symptoms include: noticeable abnormal noises from the bearing area during motor operation (creaking, clicking sounds); difficulty or even complete blockage when rotating the motor shaft; and excessively high bearing temperature, accompanied by lubricant leakage and blackening. If these symptoms occur, it indicates that the motor bearings are severely damaged. Failure to replace the bearings in time can lead to rotor seizure, winding burnout, and ultimately, complete motor failure.
