Usually the rotor of the motor is a permanent magnet, and when the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor to rotate at an angle so that the direction of the pair of magnetic fields of the rotor coincides with the direction of the magnetic field of the stator. When the stator's vector magnetic field rotates an angle. The rotor also rotates with the magnetic field at an angle. Each time an electric pulse is input, the motor rotates one angle forward. The angular displacement of the output is proportio...

Laser power according to the different ways can be divided into continuous laser power and pulse laser power supply 2 kinds. Continuous laser power supply Continuous laser power is a high-performance automatic ignition constant current power supply to fixed frequency widening the way to achieve high-precision constant current output. Output current ripple small, high stability. The ignition part adopts the three-stage freewheeling method of the series high-pressure package arc, the LC high-voltage relay and the low-voltage constant current to connect the arc current to cooperate with the ...

Laser equipment in the food industry in the application of packaging there are two. One is crossed, so that we tear the bag. Two are perforated on the bag. Everyone in the supermarket to buy things will see a lot of things on the packaging bags have holes, there is hanging so that the storage period is longer. Changxin laser on the focus on these two aspects!1. Laser scribing application    Laser scribing is a technique that uses a laser to achieve "easy to rip" effects on multilayer composite packaging materials. Traditional tools tend to draw too much of the line, resulti...
