As long as you use the brushless DC motor correctly, it can basically be used for a long time without damage or replacement. Even if it is repaired, it will not be overhauled in a short time. But I also hope that everyone can pay attention to the problem of loss of magnetism, because loss of magnetism will affect the normal use of the motor.
1. The no-load speed will increase, the load is likely to drop, and the current will increase;
2. The instantaneous current when the DC brushless motor starts is very large. It is not based on the no-load current. When the rotor is locked and the current is large, the instantaneous current can be reached when starting;
3. Constantly turn to start.
The above can help us determine whether the DC brushless motor loses magnetization. The negative impact of the magnetization loss on the motor is too great. Therefore, we must pay attention to this problem and solve this problem in time to increase the utilization rate of the motor.
