Six Problems for China small 12v dc motor Inspection
In the daily use of permanent magnet DC motors, there may be failures. Because the permanent magnet DC motor magnetic ring problem has certain dangers, it must be very strict during daily inspection and maintenance. Some parts must be processed or replaced in time if they do not meet the requirements. The following details some of the six issues that should be noted for permanent magnet DC motor testing:
Permanent magnet DC motor
In case of nonconformities in the inspection, the re-examination shall be carried out according to the arbitration inspection method in a timely manner. If the non-conformities still occur, the pre-inspection, inspection and post-inspection test records shall be completed immediately. If possible, the video records shall be used as far as possible.
2, before the inspection, should be classified according to the use of the permanent magnet DC motor being inspected, and then selected the corresponding inspection standards for inspection;
3, before the environmental test, the appearance of a prototype with unsatisfactory electrical performance, no longer transferred to the subsequent environmental test. Load the sample into the box and store it in the sample library;
4) If the test method of a certain inspection project conflicts with the test standard of the enterprise currently in force after filing(eg, there are different test methods for different temperatures, frequencies, cycles, and hours). Preference is given to the less demanding criteria;
Before the inspection, the enterprise standards provided by the manufacturer and the express quality requirements of the product shall be carefully confirmed. After the inspection begins, no changes shall be allowed for various reasons;
If the stated quality requirements of the inspected product are higher than the standard requirements on which the inspection project is based in this specification, it shall be determined according to the stated quality requirements of the inspected product. If the quality requirement stated by the product under inspection is lower than the mandatory standard requirement based on the inspection item in this specification, it shall be determined in accordance with the mandatory standard requirement. If the quality requirement stated in the product under inspection is lower than or contains the recommendation standard requirement based on the inspection item in the specification, the product should be judged by the explicit quality requirement of the product under inspection. If the explicit quality requirement of the product being inspected lacks the mandatory standard requirement on which the project is based in this specification, it shall be determined in accordance with the mandatory standard requirement.

For different types of test standards are also different, so it should be made according to different types of inspection, permanent magnet DC motor must be inspected from time to time, so as not to cause unnecessary damage.
