Reasons for overload of micro DC motor

In order to speed up the production efficiency of the product, the micro DC motor is often in a state of overload work, which will cause certain damage to the motor after a long time, and may also shorten the service life of the motor. Motor overload is an overload working state. So, what causes the motor overload? For details, we can learn about the following.

　　 1. Improper selection of the miniature DC motor, the actual load conditions used do not match the form of the selected submersible pump; the selected head is too high or too low.

　　2. The power supply voltage is too low, and the motor runs under the condition of much lower than the rated voltage, and the current in the stator winding increases more, resulting in a higher temperature rise of the stator winding and overheating and burning.

　　3, the manufacturer or the quality factor in the repair, the manufacturer and the quality factor in the repair cause the submersible pump to overload.

　　4. Mechanical failures, such as severe damage to the motor bearings, friction between the stator and the rotor, "sweeping the bore" or the impeller of the water pump blocked by other sundries such as weeds, will cause the stator windings to burn out.
