What is a Tachogenerator?
A tachogenerator gauges the speed of rotation of a shaft or disk (from Greek: tachos = speed, metron = measure) as in a motor or other machine. The device usually displays the rate of revolutions per minute (rpm) on a calibrated analogue dial. The DC motor speed is continually adjusted by the controller according to the speed measured by the tac…
More Info...Magnets Used
Tachogenerators with rare earth magnets, due to their higher energy compared to ALNICO-magnets, have a shorter time constant, assuring better performances in a closed loop process where a minimum lapse of response time is necessary. Tachogenerator manufactures normally apply a magnetic calibration of the magnets and can achieve a calibration pre…
More Info...Types of Tachogenerator
These tachogenerators all have a wound stator. The voltage and the frequency are both proportional to the speed. These models can also be used as power generators, but their quality intends them for applications of controlling a drive. The absence of contact (rings and brushes) gives these generators a good stability and a good linearity of the out…
