About the heating phenomenon of pvc engraving machine

　　PVC engraving machine , we also call it aluminum plate engraving machine, because pvc engraving machine is widely used, not for pvc sheet, there are pvc sheet, aluminum sheet, pp sheet, etc., can use pvc engraving machine to perform a high precision For processing, companies who choose to use pvc engraving machines will find that sometimes pvc engraving opportunities have heat, which somewhat affects production efficiency. Today we will take a look at the reasons for the heat of the pvc engraving machine.

　　1. The motor of pvc engraving machine is composed of iron core and winding coil. The coil will have resistance after energization, and the loss generated is proportional to the resistance and current. The iron core will also produce certain loss in the alternating magnetic field. Both the loss of the copper core and the loss of the iron core will be released in the form of heating, which causes the phenomenon of heating of the pvc engraving machine during the processing and manufacturing process.

　　2. Although motor heating generally does not affect the service life of the motor, it is unnecessary for most customers to bother. However, severe fever will bring some negative effects. For example, the different thermal expansion coefficients of the internal parts of the motor lead to changes in structural stress and small changes in internal air gaps, which will affect the dynamic response of the motor, and it will easily lose step at high speed. Another example is that in some occasions, excessive heating of the motor is not allowed, such as medical equipment and high-precision test equipment. Therefore, the heating of the motor of the pvc CNC machining center should be controlled as necessary.

　　3. The allowable degree of heating of the motor of the pvc engraving machine mainly depends on the insulation level of the motor. The internal insulation performance will only be destroyed at high temperatures (above 130 degrees). So as long as the interior does not exceed 130 degrees, the motor will not be damaged, and the surface temperature will be below 90 degrees at this time. Therefore, the surface temperature of the stepper motor is normal at 70-80 degrees. A simple method of temperature measurement is with a point thermometer, and it can also be roughly judged: it can be touched by hand for more than 1-2 seconds, not exceeding 60 degrees; it can only be touched by hand, about 70-80 degrees; drip a few drops of water quickly Change, then 90 degrees or more.
