Problems solved by technology

In the prior art, manual tools are generally used to measure the position and holding force of the iron core respectively. In view of the cumbersome testing, poor stability, and low accuracy, and most of them are destructive tests and can only be sampled, the efficiency is low, or they are not tested at all. , the inaccurate or non-detection of the test may increase the energy consumption of the motor during use and reduce the service life, which is more likely to cause hidden troubles and lead to safety risks

Abstract

The invention discloses a brushless motor stator iron core retention force testing method. The method comprises the following steps: S1, putting a stator into detection equipment, and starting the detection equipment after setting qualified parameters according to the model of the stator; s2, stator installation in-place detection is carried out through detection equipment, and resetting is carried out; comparing the first group of data with set qualified parameters, and if the first group of data is not qualified, stopping the machine and giving an alarm; if yes, entering the step S3; s3, the equipment is started again to carry out pressure testing on the iron core of the stator, and resetting is carried out; obtaining a second group of data, comparing the second group of data with set qualified parameters, and if the second group of data is within a qualified range, determining that the stator core retention is qualified; otherwise, the product is unqualified; s4, taking out the stators and classifying the stators; the device is simple in structure and convenient to use, the installation reliability of the shell and the iron core of the stator is detected through the displacement sensor and the pressure sensor, and the detection efficiency of workers is greatly improved.

Description

technical field [0001] The invention relates to the field of motor production, in particular to a method for testing the holding force of a stator core of a brushless motor. Background technique [0002] The difference between the stator of the brushless motor and the brushed motor is that the coil winding of the stator of the brushless motor is on the stator core. Or there will be poor installation position or holding force, or running vibration, etc., which will cause the stator core to shift in the motor housing, causing motor failure and even potential safety hazards. Therefore, after the stator core is press-fitted into the housing, it is necessary to detect the position and holding force of the iron core to prevent the risk of failure of the motor during use. In the prior art, manual tools are generally used to measure the position and holding force of the iron core respectively. In view of the cumbersome testing, poor stability, and low accuracy, and most of them are...
