DC Tachogenerator
DC Tachogenerator
The DC Tachogenerator is a speed transducer, which develops DC voltage proportional to speed of the motor connected to it.
Permanent Magnetic field eliminates the need of external excitation and offers extremely reliable and stable outputs. The accuracy of the tachogenerator decides the maximum accuracy of speed of the controlled machine.
