The test method and standard of the motor is a standard recognized by the motor industry and its related industries. It is a common means to evaluate the performance of the motor. For different motor manufacturers, the detection methods for components are not the same, but the final results and method criteria are the same.

Motor winding temperature measurement, for example, the most commonly used method is resistance method and PT100 temperature measuring method, from both the principle of values, the data will have a certain degree of deviation, resistance method measured temperature is the average temperature of the winding, and in PT100 temperature measurement is winding a point of local temperature, may be higher than the average temperature, also may be lower than the average temperature, of course, may also be compared with the average temperature is close to. This is the evaluation difference between the test method and the results.

For efficiency testing, there are different evaluation and testing methods in the standard, and the results obtained by different testing methods are different to some extent. In order to ensure the comparability of the data measured by different test manufacturers, for the test items with common requirements, common test methods will be determined in the standard, such as GB18613, and the test method of high efficiency motor efficiency will be tested in accordance with Method B.

In order to objectively and fairly evaluate the product quality level, THE GB755-2000 standard defines the performance index and unifies the benchmark working state of motor test and power supply quality. In order to improve the accuracy and repeatability of the test results, GB/T1032 provides qualitative or quantitative provisions on the test methods for each item. Other standards, such as vibration, noise, environmental test, turn-turn test methods, etc., are combined with specific test requirements and criteria.

If have the export business for motor test method and decision criteria may have certain difference, from the way that dates back to the standard, the standard of our country according to the equivalent, the way of equivalent and reference, setting is suitable in the production and sale within the territory of China, and not as a condition of international cooperation, especially in the design, test departments should fully understand the requirements and test methods of partners, to avoid unnecessary trouble.

Take safety certification for example, GB14711 is adopted for small and medium-sized motors in our country, but CE, UL and other certification cannot be carried out in accordance with this standard.

For motor parts and test of the machine, we adopt the common standards, but still have certain differences in detail, in order to avoid the happening of the problem, the research significance of test institutes to carry out the standard stable cross training and test, to ensure that the motor test, researchers can fundamentally. Understand the standard requirements, and shall be carried out in accordance with the standards stipulated by the right way to test.
