I'm not very familiar with electronics, and I'm trying to build a kine of regulator that will cut of the power when the out pur voltage is higher then 10V
I need it to control the speed of AC motor that has a tachometer. the tachometer is giving 3V-22V (AC) ,depending on motor speed.
I was thinking to use a zene diode and will be very happy for some help
The output voltage of the tachometer can be rectified and filtered into DC. The resulting DC can be attenuated with two resistors and fed to the input of a comparator IC that has a reference voltage that you want the motor to stop.
The comparator drives a transistor that powers the motor.
It is too complicated for you since you are not very familiar with electronics.
