Hi, I am very new to this, so please bear with me... I'm trying to come up with a DC motor circuit driver for a project using a commonly available 220v DC motor which currently has an over complicated circuit board.
Basically, I've got the guts out of a vibrating plate (Fat shaker plate). The existing circuitry whilst working very well and the motor runs well on it, has to be set up for operation, meaning there are touch sensitive buttons to tell it how long to run for and how fast to run. I want to make something way less complicated so it is just a matter of: Turn the power on, press a button, motor runs at a pre set speed for a pre set time then turns off. I have started by buying a cheap eBay motor driver, which would run the motor for as long as it's turned on, fair enough, but going off the noise coming from the motor, I'm guessing the power it is supplying to it isn't ideal, so I wanted to work out how the two circuits differ and which bits of the old complicated circuit, I need to employ in order to create a new circuit that serves my purpose. With me so far? I have done my best to reverse engineer the cheap eBay motor driver circuit to see how it works and see how circuitlab graphs its output, but for one, the circuit that it appears to be doesn't make any sense to me and circuitlab certainly doesn't seem to like it either.
