In the context of the structure of the step-motor, besides has turned from the structural part, and brush lifting mechanism, to ensure the normal operation of the motor, has made good performance in function, not only need to see to turn attention from the part whether can free rotation, turning the presence of the noise, also asked everyone to check the motor brush lifting mechanism of the following three points: to check the motor brush assembly: check the stepper motor, attention should be paid to the motor brush assembly, whether meet the requirements of assembly, if it is found that for brush assembly has a problem, it should be adjusted in a timely manner. Brush lifting mechanism is flexible: check the stepper motor, you need to determine the brush lifting mechanism assembly, on the basis of correctly through a test run, whether brush lifting mechanism is flexible and can be moved freely, if you can't to adjust its assembly. For the location of the brush handle is correct, check the stepper motor, you need to look for the location of the brush handle is correct, find handle position error timely rectification as required, or in the use of the motor can lead to poor performance. In terms of step motor brush lifting mechanism, main is to be noticed when checking the above this situation, to ensure that brush lifting mechanism is normal, can work normally. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
