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 ...
frequency inverter is a device to change AC power to variable frequency/voltage AC power, means the output frequency and voltage are adjustable, it's special used for control â¦ AC motor speed in energy saving, like fans and pumps system.5 people found this useful.Emdrgreg.ne most important thing is the out power of frequency inverter just can be used for controlling AC motor, while frequency converter can be treated as normal power supply as our daily using power grid. zhuge fs.
