Will brushless motors also overload?

Will brushless motors also overload? Yes, any motor will inevitably experience overload if used improperly. Although brushless motors have the advantages of small size, high efficiency, no carbon brushes, and long service life, they have replaced traditional mechanical commutation motors for use. Once the brushless motor encounters the following situations, be careful of overload.

1、 When the brushless motor is overloaded, it will stop directly due to the protection mechanism of the drive, and it needs to be turned off and then turned on again to operate normally.
2、 When the brushless motor is overloaded, the driver fault light flashes intermittently in green and red.

3、 If the brushless motor experiences overload, the ADC can be adjusted to slow down the start and stop time, allowing the motor to slowly load. This may lead to higher loads. There are many large loads that can be overloaded directly if they are loaded too heavily at once, because the torque of the brushless motor is low when starting to the rated speed, and only when it is locked will the torque exceed the rated torque.

4、 Although sometimes brushless motors can operate at more than twice the rated current, they can only run for a short period of time, and prolonged operation can easily burn out the motor or driver.
5、 After running for 50 minutes, the temperature of the brushless motor reaches a stable level, which is approximately 80 ° C when idling. The decibel level of the motor during operation is within 60 decibels. When loaded, the temperature may decrease because the load will take away some heat energy. When loaded or equipped with a planetary gearbox, the noise may be reduced because the motor speed decreases and the noise will be relatively low.
