RFQ Details

DC Tachogenerators give you accurate DC Voltage output proportional to speed of its mover. They are widely used in applications for feedback and display purposes.

Principle of operation

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.
