Treadmill Motor power supply PWM verses SCR Pros & Cons ?
I have a 90+ VDC treadmill motor and need a power supply controller for it.
I've read just about every thread here in this forum regarding the subject.
It looks like there are 2 basic choices. One being a circuit using PWM and the other a SCR Triac circuit.
I'm sure both will work for my needs but what exactly are the Pro's and Con's of each type of control?
I would be building my own power supply speed control and I see one advantage to the SCR design is that it would be easier to build. Where the PWM design requires more parts and a more complicated circuit design.
