I am looking for a way to control a small 12 volt DC motor (1amp.) driving a model railroad
HO scale rotary dumper. This will rotate a train car for dumping a load of ore than
return to an upright position. The control must start at approximately 8 volts and
when a timed event occurs the voltage goes to 12 volts DC. Another timed event stops
the motion waits 1 second reverses the current and goes to a timed event and drops
to 8 volts DC and continues until tripping a limit switch. At this point the current
is reversed and the sequence is ready to be repeated. I would like to be able to
control both voltage settings and both timed events with trim pots. I do not need
any more than 2 amps capacity. I plan on offering this product for sale to the
public as soon as as I complete and test the dumper.
Can you help me?
You can see the dumper on Atlas HO model railroad forum.
Thanks in advance,
Steve Paul
