Advertising engraving machine application and drive transformer features?



1. Application characteristics of advertising engraving machine: The application of advertising engraving machine is wide, and there are many application materials for advertising engraving machine.

2, advertising engraving machine drive transformer features: high security performance, good electromagnetic compatibility, long service life.

Advertising engraving machine drive transformer requirements? The advertising engraving machine drives the transformer as the spindle motor drive. The main requirement is smooth operation and smooth rotation speed change. The full speed fluctuation is small, and the low speed torque is large, which can ensure low speed cutting.

Advertising engraving machine drive transformer selection?

1. The purpose of using frequency conversion; constant voltage control or constant current control.

2. The load type of the engraving machine inverter; such as the vane pump or the volume pump, pay special attention to the performance curve of the load, and the performance curve determines the method and method when applied.

3. Matching problem between the inverter and the load of the engraving machine;

I. Voltage matching; the rated voltage of the engraving machine inverter is consistent with the rated voltage of the load.

II. Current matching; ordinary centrifugal pump, the rated current of the engraving machine inverter is consistent with the rated current of the motor. For special loads such as deep pumps, it is necessary to refer to the motor performance parameters to determine the current and overload capability of the engraving machine with the maximum current.

III. Torque matching; this can happen with a constant torque load or with a reduction gear.

4. When using the engraving machine inverter to drive the high-speed motor, the output current value increases due to the small reactance of the high-speed motor and the increase of higher harmonics. Therefore, the selection of the inverter for the high-speed motor engraving machine has a capacity slightly larger than that of the ordinary motor.

5. If the inverter of the engraving machine is to be operated with a long cable, measures should be taken to restrain the influence of the long cable to the ground coupling capacitor, so as to avoid the insufficient output of the engraving machine, so in this case, the inverter capacity of the engraving machine should be enlarged. Install the output reactor at the output of the engraving machine inverter.

6. For some special applications, such as high temperature and high altitude, this will cause the derating of the engraving machine inverter, and the capacity of the engraving machine inverter should be enlarged by one gear.

Advertising engraving machine drive transformer selection considerations? Inverter zone matching problem; according to machine spindle power selection.

Advertising engraving machine drive transformer purchase tips? The transformer used in the advertising engraving machine is generally a power supply for driving, or a power supply for stepping and servo motors, and a single phase belongs to a control transformer. Try to keep enough when shopping.

What is wrong with the power supply of the advertising engraving machine drive transformer? Mainly because the power of the electrical appliance is greater than the output power of the transformer, the current is too large, so that the voltage drop of the secondary coil is increased, so that the output voltage is reduced.

What is the advertising engraving machine driving transformer hot? The problem of the hot melt of the transformer engraving machine needs to be differentiated. The transformer will have a normal temperature rise when it is running. The 80K is normal and will have a hot feeling, but it does not contain any special hot. If it is not hot before, it is special now. Hot, you need to check the line, the line must be faulty, if it is particularly hot at the beginning, then the capacity of the transformer is chosen to be small.
