a salient pole 60 Hz synchronous motor with a squirrel cage winding on the rotor which is used for starting purposes.(a) What is the frequency of the current in the squirrel cage rotor conductors immediately after the motor is energized? (The motor was initially at standstill.)(b) What is the frequency of the current in the squirrel cage rotor conductors after the field is energizedand the machine is operating at steady state?(c) Assume the machine is initially at steady state operating at rated voltage and unloaded, when a three-phase short circuit occurs on the terminals of the machine. If you could monitor the current in the squirrel cage conductors, what would you expect to see? Explain.(d) The equal area criteria to determine if a synchronous machine will remain "stable" after a disturbance is essentially an application of the principle of conservation of energy. Very briefly describe how this process can be used to describe the response of the machine to a particular transient.
What is the difference between serial andparallel transfer. how to convert serial data to parallel andparallel data to serial. What type of register is needed.
Design a State Sequencer using T Flip-Flops and NAND Gates that Cycles through the Prime Numbers (1, 2, 3, 5, 7) in ascending order if the select input "S" is set; Otherwise (if "S" is 0) it cycles through 0, 4, and 6.
The voltage and current at the terminals of the circuit element in Fig 1.5 are zero for t
For each add instruction in this problem, assume that EAX contains the given contents before the instruction is executed, and give the contents of EAX as well as the values of the CF, OF, SF, and ZF flags after the instruction is executed.
