hi can anyone help me with design on a circuit board that will do the same as a 10kΩ pot?
The situation: I have a conveyor belt with 3 motors with gearbox,.
The problem is that the help engines do not have the same speed as the main engine.
So I would let the help engines hang freely from the shaft and attach an adjustable spring to adjust the torque.
Micro switches will give signal to the circuit board if the spring is too tight or too loose.
The circuit board must then change the resistance to the frequency converter for the motor to change the engine speed up or down.
that way the motor always give the same torque.
The circuit board must have an adjustable time delay so that the motor speed due not goes up and down all the time
Motors to day are controlled by a frequency converter that is remotely controlled by a pot 10kΩ
Thank You sorry for bad English - Google translate![Stick Out Tongue :p :p](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
