[China Packaging Network News] China's manufacturing industry has always been plagued by pollution problems after the first pollution, not only caused a lot of waste of resources in the production process, late governance is not thorough enough, and will pay more for the price. In the production of automated packaging lines, we cannot ignore short-term benefits and ignore the many problems that accompany them. How to do a green environmental protection job at the same time in the packaging...
Production line definition The production line is the route that the production process goes through, that is, the route formed by a series of production activities, such as processing, transportation, assembly, and inspection, from the time the raw materials enter the production site. The production line is organized according to the principle of the object, and a production organization form that completes the product process, that is, according to the principle of product specialization,...
An automotive generator is the main power source of an automobile. Its function is to supply power to all electrical equipment (except starters) while the engine is operating normally (idle speed) and to charge the battery at the same time. On the basis of the three-phase stator windings of the common alternator, the number of winding turns is increased and the terminals are led out, and a three-phase bridge rectifier is added. When the speed is low, the primary winding and the increased...

One-piece inductor In the electromechanical control system, most of the control signals are output by the microcontroller, such as a microcontroller, CPLD, DSP, and so on. These microcontrollers must ensure the stability of the work and ensure low power consumption. Therefore, the operating voltage of these control chips is relatively low, and the common ones are 5V, 3.3V, 1.8V, etc. These voltages can only represent the control signals. Does not have the ability to drive large power loads....
Electric vehicles have become the preferred means of transportation for the general public because of their economic convenience. In the process of using electric vehicles, there are occasions when the motor does not turn on when riding. What causes this? How to repair? First, the simplest case is that the fuse is burned. In this case, the motor is ok after replacing the fuse, and the cost of repairing the fault is also the lowest. Second, the second case is that the power switch is broken and...

A linear motor is a transmission that converts electrical energy directly into linear motion mechanical energy without the need for any intermediate conversion mechanism. It can be seen as a rotary motor cut in radial direction and developed into a plane. The side evolved from the stator is called the primary, and the side evolved from the rotor is called the secondary. In practice, the primary and secondary are manufactured to different lengths to ensure that the coupling between the primary...
