1.What should be paid attention to in using permanent magnet dc motor?
If the product is not specified, generally (for example, aluminum-nickel-cobalt permanent magnet dc motor or ferrite permanent magnet dc motor) permanent magnet dc motor is not allowed to run with reverse connection braking at rated voltage, otherwise it will cause permanent magnet demagnetization;
If it is necessary to operate this way, a current-limiting resistance should be applied to limit excessive current.
2.How to check the motor?
First, check the appearance of the motor: there should be no scratches and coating off;
Then rotate the shaft, should be flexible rotation, no obvious jamming phenomenon.
Check whether the wiring of the motor is firm and run on electricity.
There should be no friction in the process of motor rotation, the most prominent of which is bearing friction.
3.How to determine whether the bearing is worn?
Bearing wear will give out abnormal sound, local overheating temperature rise phenomenon.
Attention should be paid to permanent magnet demagnetization caused by excessive current, temperature change and open magnetic circuit during disassembly, especially for aluminum-nickel-cobalt permanent magnet motor, magnetic short-circuit protection should be carried out on the permanent magnet circuit during disassembly, otherwise additional magnetization should be conducted after demagnetization.
