Problems solved by technology

According to the conventional aging method, it is necessary to simulate the actual life of the motor. The carbon brush motor needs to be aged for more than 3000 hours, and the brushless motor needs to be aged for more than 5000 hours.
[0003] The traditional test method has certain technical deficiencies such as: long time-consuming; high investment cost; unable to quickly test the life of the motor; unable to quickly judge whether the motor components meet the requirements
Cannot simulate the situation that customers use under abnormal conditions

Abstract

The invention provides a novel fast method for checking DC motor service life. The checking method comprises the following steps: step A, acquiring 10 test motors, dividing the test motors into two groups, step B, conducting increased load test for one group, increasing the blade load, conducting the simulation based on 1.2 times of the rated current, at the moment merely adjusting the torque regulation screw rod is enough to make the motor current reach corresponding level, thus achieving the simulation of the effects caused by the motor overloading condition to the motor service life, step C, increasing the voltage of another motor group to 1.2 times of the rated voltage, raising up the motor RPM to simulate the effects caused by the motor high speed rotation to the motor service life, step D, dissembling the motors passing the tests in step B and C, determining whether the motor service life meets the requirement. The method has the advantages of being simple in operation, convenient in operation, and being able to achieve the motor service life test in a fast and effective manner.

Description

technical field [0001] The invention belongs to the technical field of DC motor life testing, and more particularly, relates to a novel test method for rapidly testing the life of a DC motor. Background technique [0002] The life of the motor directly affects the life of the fan, so monitoring the life of the motor is crucial. According to the conventional aging method, to simulate the actual life of the motor, the carbon brush motor needs to be aged for more than 3000h, and the brushless motor needs to be aged for more than 5000h. . [0003] The traditional testing methods have certain technical deficiencies, such as: long time consumption; high investment cost; inability to quickly test the life of the motor; inability to quickly judge whether the motor components meet the requirements. Can not simulate the use of customers under abnormal conditions. SUMMARY OF THE INVENTION [0004] The present invention provides a novel test method for quickly checking the life of ...
