Answer #1

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.
