Motor using line, certainly will check the equipment, in order to achieve the best of security. Check the following: new or stop using the motor for a long time, before the use should check between the winding and winding insulation resistance to ground. Usually below 500 v for the motor insulation resistance meter with 500 v; The 500 -Use 1000 v 1000 v motor insulation resistance meter; Of more than 1000 v motor insulation resistance meter with 2500 v. Insulation resistance shall not be less than 1 m Ω work every kv voltage, and measured in the condition of motor cooling. Crack was to check the motor appearance, all fastening screws and parts are complete, the caring of fixed situation are in good condition. Pull (motor shaft, check the rotor can free rotation, rotation has no noise. As is indicated in the nameplate data, such as voltage, power, frequency, coupling, rotating speed and power supply, if load is consistent. Check motor drive mechanism work is reliable. Monitor the ventilation of the motor and bearing lubrication situation is normal. Check whether the electrical grounding device is reliable. Check the motor brush and brush lifting mechanism is flexible assembly, for the location of the brush handle is correct. Motor repair prompt removal as follows: first, remove the motor wiring, and tags, for example for asynchronous motor, should do well with three phase power line corresponding tags, for dc motor, should be ready to shunt winding and armature winding and the external connection corresponding tag. Then put the foot screws loosen, separate the motor and mechanical transmission. On the second removal of the motor shaft pulley or coupling, sometimes need to add some kerosene in the gaps between the motor shaft pulley, penetration lubrication, easy disassembly. Some shaft and wheel with tighter, rapid heating, also need to round to round will be removed. Then for motor equipped with rolling bearings, should first remove the bearing cover, then loosen the fastening screw end cover, and in the end cover and base seams of the shell do mark, will be unloaded tighten screw into the motor end cover on the end cover specially set up two screw hole, the end cover out. Finally removing the motor with a brush, brush from the brush should be removed, to go to dc motor, but also will brush marks the location of the neutral line to. Spare rotor, must be careful not to touch the wound stator winding, rotor weight is not big, can be drawn by hand; Weight is bigger, should be hanging out with lifting equipment. 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.
