In the use of permanent magnet DC motor often appear when the state of loss of magnetism, but there will be a variety of different magnetic loss of the situation, there are different reasons of the loss of the operation must be careful when the operation, how to determine the permanent magnet DC motor Whether the loss of magnetic standards:
1. No-load speed will rise, the load is likely to decline, the current will increase.
2. Start the instantaneous current is very large, not to see your no-load current, you talk about the rotor turn around to see how much current to know when the instantaneous current can reach how much.
3. keep a turn to start.
