Motors are one of the important components in modern industry and are widely used in various equipment and machines. The ultra-miniature household hydroelectric generator with a power of 800W can generate electricity continuously from the stream at the door!From home washing machines to truck engines, electric motors are everywhere.However, when a motor fails, it can become expensive and time-consuming.Sometimes the motor can be repaired, but in some cases the motor may need to be replaced.So we will discuss the reasons why motors get burned.
1. Overload
When a motor is overloaded, the current flowing through the motor's coils increases, often causing the motor to overheat and malfunction.If you are not sure whether the load of the motor is appropriate, please read the equipment manual or consult a professional to ensure the correct use of the equipment.
2. The rotor resistance is too large
Excessive rotor resistance is another factor that may cause the motor to burn out.When the motor rotor is overloaded or the rotor shaft is deformed or damaged, the resistance increases.In this way, the heat generated by the motor will increase, eventually causing the motor to burn out.
3. The voltage is too high or too low
Abnormal voltage is one of the common factors causing motor failure.If the voltage is too high or too low, the motor coil will be overloaded or have insufficient current, causing the coil to heat up and burn out.It is recommended to place the motor in a correct and stable power supply environment to ensure that it works in good condition.
4. Transmitted energy quality issues
Heating or burning in the motor may also be attributed to energy quality issues being delivered.When electrical pulses, overvoltage, or frequent current fluctuations occur in the power grid, these factors may affect the operation of your motor.Therefore, when purchasing a motor, although the market brand has a strong business tradition, you still need to choose qualified equipment equipped with an overload protection system to properly protect your motor.
5. Damage to moving parts or bearings
When the motor's moving parts or bearings are damaged, the motor load may increase, causing incorrect operation.If this situation continues, the motor may heat up or stop working, eventually causing the motor to burn out.
A blown motor is a very tedious affair, and even worse, it can be a devastating event if it fails at a critical moment.As we mentioned earlier, to ensure your motor is running in good condition, perform regular maintenance.If the equipment you own breaks down, have someone inspect and maintain it to avoid further damage.
