In the field of modern industrial automation, variable frequency drives (VFDs) have become an indispensable part. They not only change the speed of three-phase AC motors but also offer a variety of control functions such as non-emergency start and stop, acceleration and deceleration, overload protec...
In the field of industrial automation , [color=rgb(68, 68, 68) !important] frequency converters are important equipment for driving motors , and their stability and reliability are directly related to the smooth operation of the production line. However, frequency converters often encounter overload...
Starting a 380V three-phase cage motor is an old problem. It seems that there was an answer decades ago, but it is almost a new problem. Most of the answers now cannot stand the question of why? Or they are not practical. Let me first talk about the existing answers (please add if you haven't said a...
Each relay has a name, and generally the normally open point and normally closed point share the same name with the relay. If there are 10 relays, there will be 10 names, as long as each relay and contact is not confused with other relays. Wiring diagram of small solid state relay Small relay wiring...
When lithium-ion batteries (LIB) are used, stored or transported, if they are subjected to external overloads (overcharge or short circuit, vibration, impact, high and low temperature, etc.), the following phenomena may occur: l Thermal runaway l Electrolyte leakage l Internal gas leakage caused by ...
