Best way to go from AC to DC motor in a sewing machine?
So my wife's sewing machine motor died recently and it costs 115 dollars to fix it which is just about the cost of the machine. I have a 12V, 100W scooter motor that I can adapt to the machine pretty easily. The problem is that the old motor was AC. The machine has some nice features so I wanted to run the DC motor with the AC that the machine outputs. My plan was to use a full bridge rectifier on the AC output and then a simple voltage divider to get the max voltage to 12V. What I am wondering is if this will work. I know normally you would use PWM but then things are more complicated. Will the 120 Hz ripple affect the motor? Will my method put a lot of strain on the DC motor? Will this even work? Thanks.
