Participants suggest examining the tachogenerator's construction. In addition, the dc tachogenerator output is a pulsating voltage, and its alternating component has a significant influence on the speed feedback. A tachogenerator in an industrial machine is responsible for transmitting information about the actual rotational speed to the drive system, which is why an incorrect signal can cause unstable drive.
(Solved) - A variable reluctance tachogenerator, like that shown below
What causes the fanuc tachogenerator disconnect alarm
The alarm triggers when the servo amplifier loses feedback from the motor encoder
Common causes include encoder failure,. A tachogenerator is a small dc generator designed to output a voltage directly proportional to the speed of a rotating shaft. A tachogenerator is attached to the object whose speed is being measured — such as a fan or motor shaft — and evaluates the voltage of the power produced by the generator to determine the rotational speed. I'm currently having trouble with detecting the rpm frequency from a tacho generator signal
I have tried everything i know My tacho generator is attached to a universal washing machine motor,. Obviously the output voltage is proportional to the speed
