aFig.2 shows the stator copper losses of the different phases of the machine.As shown, the losses of phase a and b are increased by increasing the voltage unbalance, while the losses of phase c decrease 显示机器的不同的阶段的定子铜损失。如所示,和b增加电压失配增加阶段a损失,而阶段c损失减少...
Recycling is crucial for achieving sustainability. Extracting virgin metals from ores is energy-intensive and environmentally damaging. Metals like aluminum, steel, and copper can be recycled indefinitely without compromising their properties, reducing the need for mining and processing new materials. Recycl...

Metalworking predates earliest civilizations for a long time. Metal objects of copper have been dated back to as early as 8700 BC. Early metalworking processes were very basic, such as hammering. In later millennia, metalworking began incorporating heat to melt and reform the molten metal. Where ...
The simplest metal coupler units utilize a simple compression or clamp design. Once they are in place, force is applied to the outside of the coupler, which causes it to grip the object within using compressive strength. Similar bar or beam metal coupler designs can be used to join two sma...
