Student: I can't figure out how to do that, since I can't seem to cut off more than two of the four corners. Mentor: Don't worry, what I asked you to do is actually impossible! There are only six faces on a cube, so the highest number of sides possible is six. Student: That makes sense. I bet you can do that with any prism-it's just a matter of angling the cross section correctly to intersect all of the faces. Mentor: You're very right, any prism can be cut in such a way that the cross section has as many sides as the prism has faces. However, not all shapes have this same property.
A variable frequency transformer including: a first parallel circuit including at least two of the rotary transformers arranged in parallel and having an isolating circuit breaker connected to a rotor winding of each of the rotary transformers, and a separate synchronizing circuit breaker connected to a stator winding in each of the rotary ...
Saving energy now! Frequency inverter also called frequency converter, it is a power control conversion device to convert normal power supply (50Hz or 60Hz) to another frequency power by inner power semiconductor on/off behaviors, to control electric motors in variable speed operations.hen the frequency inverter is installed, it can decrease the pump speed from N1 to N2 with the pipe network resistance curve (1) being unchanged, so the working intersection A transfers to C. At this time, the consumed axis power can be represented by the area of H3COQ2.
