Synchronization of clock of satelite with devices here on the Earth 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. So how can achieve synchronization of the clock of the satelite with our clock in order to for exampl... (more) |

Understanding induction motors 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 until 4:40 it describes how the speed of the rotor oscillates between the speed of the stator and a spee...

Contradiction between Routh's algorithm and checking with some value 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 $G{c}(s) = \frac{K}{s(s^{2}+4s+3)+K}$ I tried fin... (more) |

Confusion in operation of analog computer 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: Image alt text The variable resistor is basically a voltage divider between VCC and VEE and you can change the output voltage by changing ... (more) |

How is it possible to perform a open circuit test on a induction motor? 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 the stator/rotor will be ... (more) |

What are these transformer graphs about? 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 side?And what are $I^{'}{2}$... (more) |

Calculate values of externally excited DC generator/motor 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 to a load. Now we use the same DC externally excited generated/motor as a motor with 10V input volta... (more) |
