Why does DC motors catch fire?

To be able to react quickly when there are issues with DC motors, we need to be proficient in certain fundamental common sense in addition to regular procedures when using motors. Vshida Micromotor will explain the cause of the DC motor fire to you today.

1. The insulation and neighboring combustibles are burned as a result of the terminal's loose connection, which results in an excessive contact resistance and local heat generation.

2. Because the two-phase windings' current is excessively high due to the three-phase motor's lack of phase operation, the windings overheat and burn.

3. The motor inhales excessive amounts of fiber dust, which obstructs the air duct, which leads to inadequate heat dissipation of the coil and winding and an increase in temperature.

4. The insulation on the motor coil windings is short-circuited as a result of mechanical damage, moisture, aged insulation, or overvoltage failure.

5. The motor starts up quickly and frequently, and the motor current is excessively high, resulting in the motor overheating.

6. The mechanism is stuck, the voltage is too low, or the motor is overheated and heated as a result of the enormous load it is driving. In extreme circumstances, the motor might potentially catch fire and become charred.

The six causes of the DC motor catching fire are listed above. Contact us for more details about micro-motors, and we'll get back to you within a day.
