The first is that with the continuous improvement in the performance and stability of stepper motors, CNC batch flower machines are widely used in some motion controllers. It is widely used in the high light machine industry. Because its internal structure is composed of an iron core and a winding coil, it will generate a certain amount of heat when it is energized, and it may even be hot if it is operated for a long time. To what extent is the motor heat normal? How to reduce the heat generated by the motor? Here we come to a simple solution.
The temperature range in which the motor heats up depends mainly on the internal insulation level of the motor. In general, the numerical control batch flower machine will be damaged at high temperature (above 130 degrees). Therefore, 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. Therefore, the surface temperature of the stepper motor is normal at 70-80 degrees. A simple temperature measurement method is useful for a thermometer. You can also make a rough judgment: you can touch it with your hand for more than 1-2 seconds, not more than 60 degrees; you can only touch it with your hands, about 70-80 degrees; It turned 90 degrees or more.
Motor heat generally does not affect the life of the motor, and it is not necessary to worry too much for most customers. However, severe fever can have some negative effects. For example, the different thermal expansion coefficients of the various parts of the motor will cause changes in structural stress and small changes in the internal air gap, which will affect the dynamic response of the motor, and it is easy to lose steps at high speeds. Another example is that excessive heating of the motor is not allowed in some occasions, such as medical equipment and high-precision test equipment. Therefore, it is necessary to control the heating of the motor. When the motor temperature is too high, you can choose to stop the machine, rest for a period of time and continue working, you can also add a radiator to the outside of the motor to ensure that the heat of the motor is released in time.
The main body of the machine is made of marble; the machine is stable and not deformed, and the vibration during movement is small. It is the first choice for the <a href=”https://www.cncmachiningptj.com/”>CNC machine</a> to ensure that the precision does not deform permanently.
