: The rotor (armature) is rigidly attached to the machine shaft being measured.
Tachogenerators work on the principle of . Tachogenerator
A tachogenerator is an electromechanical device that outputs a of a rotating shaft. It acts as a specialized sensor used primarily in speed control feedback loops for motors, industrial machinery, and automated systems. ⚡ Core Operating Principle : The rotor (armature) is rigidly attached to
: As the armature rotates through a fixed magnetic field (often created by permanent magnets), an Electromotive Force (EMF) is induced. an Electromotive Force (EMF) is induced.
