We use a DC externally excited generator/motor as a generator.We excite the input of the generator and get at the output 10V at 1Wb flux and at 5rps generator speed without connecting the generator...
During the open circuit test of a induction motor ,not any current flows inside the rotor.But how can we achieve such a thing? Here is the ping configuration of a induction motor: The coils of ...
I am designing a control system controlled by some microcontroller K: The open loop gain is $G_{o}(s) = \frac{K}{s(s^{2}+4s+3)}$ and the closed loop gain is obviously $G_{c}(s) = \frac{K}{s(s^{...
Serial communication protocols require synchronization of the clock of the connected devices. From GR the time elapsed for the satelite is different than the time elapsed for us here on the Earth....
I have been watching this video and at 3:28 it says that a induction is inherently self-starting.Does this happen because of the energy stored and released in the windings of the statorFrom 3:41 u...
I have been reading about thermal noise in resistors and I have a question: Suppose we have this circuit: Is C2 here to protect the voltage source from thermal noise?
This picture describes the behaviour of a single phase transform under resistive,inductive and capacitive loads(from left to right) How what exactly is $V_{1}$ ?Is it the voltage at the primary ...
I am studying for a test in control systems and we have a practical part which is to program a analog computer. Here is a picture of the analog computer: The variable resistor is basically a vo...
