Hi there,
I'm trying to design a speed motor control circuit. The idea is by controlling each half of the voltage period applying to the load by using an optocoupler - MOC3021 and a triac - BTA06-600b.
The problem is the output of MOC 3021 seems incorrect. The reason is I use pulse source (to simulate output of microprocessor) to control firing angle but the output of MOC 3021 still the same.
Please tell me where is my mistake.
Thanks,
