1. Application scenariosControl type motors in the field of automation can be divided into servo motors, stepper motors, variable frequency motors, etc. In components that require more precise speed or position control, servo motor drive will be chosen.The control method of frequency converter+variable frequency motor is to change the motor speed ...

1. The lens has stains or scratchesSolution: If there are stains, you can use a cotton swab and alcohol to wipe the lens, beam expander, and focusing lens, wiping off the surface material. Remember not to use hard objects to wipe the lens; If there are scratches or other damages on the lenses, the only option is to replace the marking machine lens....

Generally speaking, when the stepper motor has been confirmed, we mainly select the driver based on the motor's current, subdivision, and supply voltage.1. Determine the torque required for the load carried by the motor, and the torque of the selected driver must meet the motor's usage.2. Determine the rated current of the stepper motor used, and...

The principle of a laser marking machine is to vaporize the surface of a material in an instant through the high temperature generated by laser focusing, and generally the color of the material itself is printed out.The color of metal laser marking mainly depends on the nature of the material, followed by the size of the laser force (i.e. power, ...

The causes of cracksDuring the fusion process, the high-energy laser beam rapidly heats up, causing a significant temperature gradient between the fusion layer and the substrate. In the subsequent cooling, the volume of the cladding layer and the substrate is inconsistent, which constrains each other and generates stress.During the growth process ...

Chain transmission usually includes the following types. The first type is a very ordinary roller chain, and the sprocket mainly has two parameters: tooth number and pitch circle. When designing, only the strength of the chain needs to be considered, and then the pitch of the shaft and chain need to be selected based on the transmission power. The ...

1. The DC servo motor used as a DC servo motor usually has a separate DC power supply in the winding and armature winding fields. This control can be archived by controlling the armature current or excitation current. Magnetic field control includes some special advantages over armature control. Similarly, armature control also has some advantages ...

Laser cooling is a technology that utilizes the interaction between laser and atoms to reduce atomic motion speed and obtain ultra-low temperature atoms. During the laser cooling process, multiple laser beams illuminate the target atoms from different directions, subjecting their particles to the pressure of light to prevent their thermal vibration...

The stepper motor is now widely known and applied by most people, which is of course determined by its own advantages and performance. Especially the step value of the motor is not affected by various interference factors. Such as the magnitude of voltage, the value of current, waveform, temperature changes, etc.Also, the error of the stepper mot...

Firstly, the focus position of the fiber laser cutting machine affects the cutting accuracy, especially the diameter of the focal spot. The diameter of the focal spot should be as small as possible to produce a narrow slit; The diameter of the focal spot is directly proportional to the depth of focus of the focusing lens. The smaller the depth of f...
