I am curently working on a project (automated scenery, to explain the
crosspost) for which I need a 300 watt motor. I'm looking at a 300w 24v DC
motor, since I am pretty comfortable with DC motor speed and direction
My problem is in coming up with the power source for that. I prefer to buy
a readymade power supply, but everything I'm seeing is either $1000 or "not
for variable loads." I'm not adverse to building a supply, but I know
little beyond the fact that I need a transformer, rectifier, and regulator.
Any suggestions? If the best answer is, "Learn how to control AC motors,"
I'm open to that, but I've been told that AC motors don't reverse well and
don't operate well at low speeds. This project has to change speed and
direction fairly rapidly.
Thanks in advance.
