Common woodworking engraving machine spindle motor failure analysis and their solutions

First,Wood engraving machine spindle motor is hot:
Solution: check the water pump is working, as well as to look at the next cycle the water is low at the liquid surface.

Second, I feel the motor no effort, turn no:
Solution: Look at the circuit, and check whether the motor line phase loss, or whether the cable is short-circuited.

Third, the motor made strange noises:
Solution: Check whether the motor is overloaded; possible motor internal fault, should be promptly repaired or replaced.

Fourth, the motor runs in reverse:
Solution: directly check whether the motor line phase loss or output UVW end exchange.
Wood engraving machine machine axis does not rotate:
Check wood engraving machine corresponding axis corresponding to the drive block is damaged;

Check the following steps:
1: wood engraving machine fixed axis the aviation corresponding plug unplug;
2: Then plugged movable shaft corresponding to the drive, the observed phenomena. Dynamic description of the normal; fixed it cable or motorfailure, the need for timely replacement, wood engraving machine the shaft driving the corresponding block corruption, the need to replace the driveblock.

Wood engraving machine spindle does not turn the common troubleshooting and repair methods

  1. 1: The inverter power small selection of the inverter power level;
  2. 2: Motor insulation class to meet the requirements;
  3. 3: The output side of the short circuit, the motor cable is damaged;
  4. 4: Acceleration overcurrent acceleration time is too short, extension of acceleration time;
  5. 5: appropriate to reduce the V / F compensation value;
  6. 6: V / F curve inappropriate choice of V / F curve, adjusted in accordance with the actual situation of the load;
  7. 7: implementation of the re-start of the rotation of the motor until the motor is completely shut down before starting;
  8. 8: overloaded, reduce the load;

Advertising engraving machine classification

Divided into two categories of low-power engraving machine and high-power engraving machine computer engraving machine from a functionalpoint of view. Low-power engraving machine is the the smaller engraving machine engraving motor power (typically 80-200W), each can only be applied to the cutting surface less fine processing, due to its smaller power carving motor. Such as: badges, sand table model, crafts surfaceprocessing. Such engraving machine can not be high-power engraving and cutting. The high-power engraving machine engraving machine theengraving motor power of more than 700W. Such engraving machine can not only low-power engraving, can also be a high-power engraving. 

Such as: the production of crystal word, all kinds of advertising signs, irregular sheet metalforming, artificial stone processing. Because of its power, one can cut 30mm hick plexiglass power molding carving or molding knife. Some users do not clear engraving machine with high power and low power,saw a demonstration of high-power engraving machine, because the investment is difficult to buy a slightly lower price of the low-power engraving machine. The results can only be carved breastplate less than two yuan each (some areas only a few cents a) engraving of the plexiglass signs such as high-power, only to see someone else do it. 

The same investment, same store expenses, the same operation, and other staff salaries,there are 80% of the engraving business can not do, not only to reduce their own benefits, but in a very disadvantageous position in peer competition. This point in the choice of engraving machine, be sure to pay attention to. If you are in this industry applications, be sure to buy thehigh-power engraving engraving machine.

Engraving machine motor drive troubleshooting examples

Summary: motor engraving machine control components, motor failure, a serious impact on the normal operation of the engraving machine, and remove the motor failure is particularly necessary.

Failure phenomenon: Once activated, the drive is an external fuse that burned, the device can not run. Maintenance personnel in the inspection, found a damaged power tube, but the absence of information, unclear about the role of the tube, thought it was a power-driven front to promote and put on a power tube, energized, insurance re-burned, for on the tube also damaged.

Professional maintenance staff to check the initial analysis is that insurance has repeatedly blown, the drive certainly exists of a normal high-current, and check out a power tube damage. However, the role of the tube is not clear. Actually the tube starter for stepper motor power drive pipe, stepper motor for high pressure, they would have to withstand high-pressure high-current. Static checking and found that the pulse annular distributor line, its power to end the resistance of a small, but not short-circuit. Analysis based on the number of components in the circuit and its power consumption with the power to end the resistance should not be so small, it was suspected that the line is already damaged components.

Power check, found a chip abnormal fever. After power cut off the power supply pins of the chip static checking, the resistance set increases power to the ground should be normal. Measured the chip’s power supply to ground resistance is very small. Check the model of the chip, is a non-standard model, not found in many manual. Line analysis confirmed that the main components of the board: the ring pulse distributor.

To further confirm the chip problem, first change the withstand voltage the considerable current power stepper motor power drive pipe, to restore the power supply pins of the chip, with a light-emitting diode circuit alternative to stepper motor windings simulated load. Energized, the light emitting diodes are bright, i.e. the respective windings are energized, which is incompatible with the line requirements, no response to the input step pulse, and it was confirmed that the chip has been damaged. However, the chip market not, in the case of space permits within the drive housing, using a combined line i.e. hand head has a D flip-flop and a ring pulse generator in combination with a non-gate design, production in a small printed system board, remove the original chip small printed circuit board via pin mounted in the original chip pads. Still light-emitting diodes for analog load, plus people stepping pulse energized phase sequence turn luminous. Removal of simulated load, access host energized equipment is running properly.

This example illustrates: maintenance personnel must not only be able to analyze the phenomenon (over-current), to find out more obvious reasons (power tube damage), but also be able to step-by-step deep analysis of failure (damage to the pulse generator), and be able to use at the beginning of existing components portfolio on hand to alternative devices difficult to solve problems.
