Not only is the new purchase of stepper motor, the need to conduct a comprehensive inspection before use, to stop using the motor for a long time, we also need to make comprehensive inspection, after check no problem, only to be able to start and use. Including the motor stopped for a long time to check, whether there is any damage in addition to the required everyone to check motor structure, mainly is the need to check all of insulation resistance between the winding and winding. Both new stepper motor, and stop using the stepper motor for a long time, once to ground insulation resistance between the winding and winding problems, can pose a safety hazard, use machine in this state, both the motor structure and the surrounding environment and people will pose a safety hazard, very prone to security issues. So ask everyone in need to use long-term outage of motor, first to ground insulation resistance between the winding and winding condition for inspection. Is specific stepper motor to ground insulation resistance between the winding and winding, motor should be used under 500 v, 500 v insulation resistance meter, if it is 500 -You need to use 1000 v 1000 v motor insulation resistance meter, more than 1000 v motor need to use 2500 v insulation resistance meter. At the same time to ensure that the work every kv voltage insulation resistance in 1 m & Omega; Above, at the same time attention should be paid to this aspect of measurement should be done under the conditions of motor cooling. 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.
