In order to fix the phase angle in the fixed phase of tachometer generator at 90 degrees
Tachometer generator is a micro-electric machine used to convert, the rotating speed and the shaft values of a machine into an electric signal . The operation of the tachometer generator is based following principle
The angular velocity of rotor is proportional to the generated EMF if the excitation flux is constant
These tachometers are specified with generated voltage,
accuracy, maximum speed, ripples and operating temperature. This
kind of tachometer generators are used as sensors in various
automobile and electro-mechanical computer devices.
Further these can be of both types AC as well as DC.Their phase
angle can be accordingly changed by variating above
electro-mechanical parameters.

In order to fix 1 car tire, jerry fixed 3 bicycle tires. In order to fix 1 car tire, berry fixes 5 bike tires, who has the comparative advantage Please answer carefully. Thank you!
why is the angle 0??? when a 3-phase 4 pole 6.6 KV, 12MVA generator is ran as a motor supplying its full load with unity power factor (=1).
Part 1: If the angle the displacement makes with the electric field is 90 degrees it means the charge is moving across (or perpendicular to) the field vectors. Is work being done and what is doing the work? Will it be maximum, minimum, or zero? Explain your answer with a diagram. Part 2: If the angle the displacement makes with the electric field is 0 degrees it means the charge is moving along (or parallel to) the field vectors. Is...
