Maintenance for converter motor on cnc wood router1. In case that an increase in noise and vibration occurs to the cnc wood router motor, it should be considered as the result of bearing wear, and the machine requires timely replacement.
2. In case that an abrupt stalling occurs, or an unusual odor gives out during operation of cnc wood router, immediately cut off the power, and then point a megameter measuring stator to the insulation resistance and measure the symmetry of the three-phase resistance. When the difference between the maximum/minimum values and the average value of the phase resistance exceeds 3%, or the insulation loses out, the stator is determined to be burn out and should be timely repaired.
3. After being placed for many days, the electric spindle of cnc wood router should be operated without load for half an hour before starting operation, to enhance the stator’s insulation performance.
4. During maintenance, storage and transportation, the dust proof cap of cnc wood router should be mounted at the inlet of cooling water, to prevent sewage from entering the water passage.
