The influence of magnetic missing on DC motors will affect the normal use of the motor. Therefore, we must learn to determine whether the motor is missing before using the motor. Once you are not magnetic, we need to take corresponding measures to remedy. How to determine whether the motor is lost. magnetic?
1. The speed of the air load will increase, the load is likely to decrease, and the current will increase;
2. The instantaneous current when the DC motor starts is very large. It is not to see the air load current.
3. Keep turning to start.
To determine whether the DC motor is missing, we need to determine whether the magnetism is missing according to the above method. If you have a magnetic loss, you must solve this problem in time, otherwise it will affect normal use.
