DC voltage tachogenerators

DC voltage tachogenerators in built-in design, used as a motor speed sensor or device used in control systems as feedback.

We are the manufacturer of the PATO 78-14 tachometer. The standard design, used in servo motors of our production, has a voltage constant of kE = 31.5V / 1000rpm.

We also offer tachogenerators based on the PATO 78-14, but with windings for other voltages based on customer demand.
