Draws a line (a direct path between two points) to the screen. The version of line() with four parameters draws the line in 2D. To color a line, use the stroke() function. A line cannot be filled, therefore the fill() function will not affect the color of a line. 2D lines are drawn with a width of one pixel by default, but this can be changed with the strokeWeight() function.

motors used in electric vehicle traction. Processing and design features are reported that produce die cast copper rotors having improved motor efficiencies in-line with motors employing fabricated copper rotors. Two possible mechanisms are identified that explain the previously low efficiencies shown by die cast rotors at high rotational speeds.

Once the liquid copper is at the correct temperature, the furnace is tilted hydraulically to pour a controlled amount of liquid copper into a ceramic cup (see Figure 9.4.2.2). A robot is then used to pick-up the cup and transfer the liquid copper to the shot sleeve of the die-casting machine.

The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to …

For UHSPMSM, the total copper loss considering the influ-ence of alternating the electromagnetic fieldis definedas AC copper loss, which includes DC copper loss and eddy current copper loss. Therefore, AC copper loss is expressed as follows: pac ¼ pdc þ peddy ð1Þ where Pac is AC copper loss, Pdc is DC copper loss and Peddy is eddy …
