Everyone in the use of stepper motor, all is the use of the function of the motor is required to optimize the use of related equipment, or to maintain the normal conduct of certain work. Therefore all natural has higher requirement in function of motor, and need to make sure that the motor has been normal function. If you want to do this, you need to everyone in the use of the motor, do these checks before starting motor: first, in order to ensure the normal order of the stepper motor in terms of function, ask you before start the motor, by flipping the motor shaft, check the rotor can free rotation, and whether there is noise when listening to the rotor rotation, to determine the rotation of the motor is normal. Second, from the perspective of the functional aspects of stepper motor, need everybody in their daily before use, check the motor brush and brush lifting mechanism is flexible assembly, by ensuring that brush assembly condition meets the requirements, guarantee for flexible brush body, but also guarantee for accurate location of the brush handle, to do a good job in security on the function of the motor. Third, check the motor grounding device is reliable. The normal function of the step motor, is based on motor can security applications, so to ensure normal motor function, the first thing you need to ensure the safety of motor applications when dead, this will require you to check the motor before initiating grounding device, whether this part of the decoration is reliable enough. 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.
