(1)Wound rotor motor USES the wound rotor type, and the structure of the stator winding and rotor winding are built around the same, so the fault inspection methods and troubleshooting methods are the same. (2)Excessive sparking on the collector ring fault as follows. (1) oil or debris collector ring, elimination method: remove dirt, and use sand paper will play polishing collector ring. (2) the surface of the collector ring wear or spark burned, elimination method: slight damage can use a sandpaper down, should be fine car collector ring damage more serious to the roughness of 2. 5, radial runout is less than 0. 4 mm, keep low brush and collector ring spacing around 3 mm. (3) brush pressure is too small or stuck inside the brush holder, elimination method: put brushes and adjust brush pressure and check the fitting clearance of brush and brush box, if the clearance is too large replaceable brush, if the gap too small coke appropriate grinding brush can slide freely. P (4) brush wear serious or brush, brush contains impurities, elimination method: change the brush quality qualification of the original specification. (3)Motor rotor winding winding again after the dynamic balance is bad to can cause motor vibration is too large, elimination method: check dynamic balance again. (4)Motor rotor winding circuit can cause abnormal voice, decreased after the start torque, motor speed is reduced, elimination method: find the cut-off points after repair or replace the rotor winding. (5)Arc short circuit fault between brush and slip ring, brush on the conductive powder too much off, elimination method: in a timely manner with the brush dust removal tool to remove accumulated powder: bakelite gasket is broken, and elimination method: replace the insulation on the collector ring gasket. 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.
