  Common faults of servo motor and their solutions

  Servo motor can make the control speed and position accuracy very accurate, and can convert the voltage signal into torque and rotational speed to drive the controlled object. Servo motor rotor speed is controlled by input signal, and can respond quickly. In automatic control system, it is used as ...

  What is the inverter?

  Introduction Inverter is a device that converts direct current energy into alternating current (generally 220V, 50Hz sine wave), which consists of inverter bridge, control logic and filter circuit. Inverter is a DC-to-AC transformer, which is actually a process of voltage inversion with converte ...

  Does the residue of PCBA process affect the reliability of PCB?

  The residue on PCBA mainly comes from the assembly process, especially the welding process. Such as flux residue used, reaction by-products between flux and solder, adhesive, lubricating oil and other residues. Other sources are relatively less harmful, such as pollutants and sweat stains caused by ...

  Working mode of stepper motor driver

  1. The whole step drive In the whole step operation, the same kind of stepping motor can be equipped with either the whole/half step driver or the subdivision driver, but the operation effect is different. The stepper motor driver circularly excites the two coils of the two-phase stepper motor a ...

  How to reduce harmonic distortion in PCB design

  Actually, the printed circuit board (PCB) is made of electrically linear materials, that is, its impedance should be constant. So, why does PCB introduce nonlinearity into the signal? The answer is that the layout of PCB is “spatially nonlinear” relative to the place where the current f ...

  How to choose power chip in driver PCB design

  When designing PCB, it is necessary to choose DC/DC or LDO for power chip design. To put it simply, only DC/DC can be used when boosting, because LDO is a voltage drop type and cannot boost. When the designed circuit has the following requirements for shunt power supply, it is best to cho ...

  Differences between OBM,ODM and OEM in processing field

  OBM:OBM(Orignal Brand Manufactuce). That is, the foundries operate their own brands. Because the foundries need a perfect marketing network to support OBM, the cost of channel construction is very high, and the energy spent is far higher than that spent on OEM and ODM, and they often conflict with ...
