Hey everyone!
I am a relative newbie to electronics and was hoping to get the advice and suggestions of those who are wiser in the subject than I. I am putting together a demo of a Hoeken's linkage for my Machine Dynamics class, but I would like to motorize it to avoid tedious hand-cranking. For this purpose, I have purchased a low-rpm 24 VDC motor that I would like to be able to plug in and avoid having to constantly buy 12V alkalines to run the thing.
Now, I have built a simple bridge rectifier using 1N4004 silicon diodes and a 120VAC/12VAC transformer in the past, but that was years ago and my requirements for this bridge are a little different than that one. So, I was hoping for tips or advice on a few things:
1) For a rectified 24 VDC, I would require a transformer with 16-18 VAC output on the secondary windings, is that correct?
2) What sort of VA rating should I be looking for on the transformer if I intend to use this motor (175mA @ no load)?
3) I would like to maintain a steady DC voltage, so I know I have to use a capacitor for filtering, but how much capacitance would be required?
4) If I wish to wire in a switch, should that be wired to the power supply or just the motor?
Any help that anyone could offer would be greatly appreciated. Thanks!
