Hello,
I'm new to the forum. I'll do my best to ask an intelligent question
I have a BLDC motor for a sewing machine that I want to fit to my milling machine. It has everything I need, except: the variable speed start circuit is designed around a red led and photoreceptor with a spring activated blade that interrupts the light to the photoreceptor. I want to replace this circuit with a variable resistor like a Triac.
I have read up on photoreceptors in general, but I can find no markings on the photoreceptor to identified it. I measured resistance across the legs in the dark 35kOhms, and in bright light its 65MOhms.
Is it safe to replace this with a 100MOhm variable resistor to test and tune the needed resistance?
Any suggestions?
Thank you for any help.
