Abstract: the optimization of stepper motor applications need to tear open outfit, correct disassembling correctly or not directly affects the correct use of the motor, and even cause the damage of the parts, so people pay attention to his tear open outfit, avoid artificial installation errors. This paper is to introduce stepper motor when disassembling matters needing attention. One, according to the instructions manual for people when disassembling of stepper motor must be in strict accordance with the instructions manual and specifications for the corresponding dismantling work, remove the program and install exactly the opposite, only in strict accordance with the operation process to tear open outfit can effectively avoid installation and remove the error. Second, people can't damaged parts in to tear open outfit, stepper motor also note cannot be damaged parts. For example: when removing end cover, not the bulge stator coil to the outside of the frame that touch an injury; When placed in the rotor, put it in as far as possible on hardwood pad, and the liner can't mat underneath the slip ring. Three, the components of step motor at the time of installation, counting to all of its components and product manual control, can only be carried out only after all the components are complete installation, when sealed, also want to remove the components counting, only a full range of parts, can be unified. Axis. 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. Telephone:
