Per my other thread, I think I have the encoder issues resolved. I went ahead an ordered the LSI/CSI encoder counter chips. Hopefully that will improved the repeatibility of the encoders.
I would like to control the AC motor that comes stock on the sewing machine.
Currently the speed of the machine is controlled by Variable Router Speed control.
The speed is dialed in and then a relay turns the machine on an off.
Now my question as a electronics newb. Is there solid state device that will do something simliar that is variable based on input?
I don't think that there is a VFD (variable frequency drive) inside the little 19 dollar box. I'm assuming that there is some type of potentiometer/Variable resistor or like device. ((I haven't cracked the box yet))
I want to be able to vary the motor speed based on the encoder output.
I realise that I won't have near the control that I would have had with the DC motor/gecko via step and direction. However, the wife changed the requirements. She wants to retain the existing motor.
At least in the short term.
Thanks for any help.
