hello,i have purchased a cheap dc motor with controller (which is not working) from an old treadmill hoping to make my own controller.
the motor is 3hp rated for 180V DC
i tried to track the original controller to see how it worked.
partially finished schematic included.
i noticed that the controller used the rectified 220VAC directly to drive the motor(308v dc!!)
my questions is :
1-is it ok to drive 180V dc motor from 308V dc?
2-what is the difference between pwm drive and scr based driver and which is suitable more in recent case?
3-is it convenient to use adjustable buck converter to drive this motor?
