If a stepper motor has a step-angle of 7.5? , what digital input rate is required to produce a rotation of 10 rev/sec?
What will be the step-angle for a hybrid stepper motor with eight stator windings and ten rotor teeth?
How many steps/pulses per second will a microprocessor need to output per second to a stepper motor if the motor is to give an output of 0.25 rev/sec and has a step-angle of 7.5? ?
Compare and contrast brush type D.C. motor and brushless D.C. motor. What advantages does brushless motor have over brush type motors?
Explain how a thyristor can be used to control the level of a D.C. voltage by chopping the output from a constant voltage supply.
stochastic message signal, m(t), is transmitted down a (noiseless) cable channel by PCM, using an 8-bit code. If the ambient signal is equally likely to lie anywhere between its two extremes, (+/- mp), calculate the ration of the mean squared sign..
A 240kW 500V 1750 r/min separately excited dc generator has an overall efiiciency of 94%. The shunt field resistance is 60 ohms and the rated current is 5A. The I^2 R loss in the armature is 0.023 pu.
