Hi,
I’m planning to build a motorized camera platform for taking those fancy time-lapse quicken shots.
I’ll use 3 Lynxmotion PGHM-18 12vdc 3.8A Gear Motors for positioning the platform in 3 axes.
The speed of the motors will be very, very slow, like rotating the platform for 360’ in about
24 hours or so, and therefore I think it should be done by driving the motors with a series
of short PWM type pulses.
There are two parameters I should be able to control with appropriate software: pulse duration,
and pulse frequency, for each motor independently.
For example, a 50ms pulse every 3 seconds for motor 1 and a 90ms pulse every 10sec for motor 2, and so on…
What kind of motor control unit and software should I chose, to be able to control the
motors in this manner ?
I’m not looking for a real time control of the motors, but would rather set up the parameters
and let the PC do that pre-programmed sequence.
Is SSC-32 with the Sequencer software a good solution for this setup, or should I look
for something else more appropriate ? Can SSC-32 handle 12V and 3.8Amps for 3 motors ?
Or do I need some sort of aditional driving PWM unit to power the motors ?
Please help.
I’m generally looking for some ready-made unit cause I’m not an electronic expert, at least not yet 
Any recommendation is greatly appreciated!
Thanks!
The SSC-32 is a servo controller. It outputs servo pulses not PWM pulses they are quite different. Check what’s a servo on the main page at www.lynxmotion.com. I deleted the other post in General Discussion. There is no need to cross post on this forum.
I’m sorry, I have first posted in General Discussion forum by mistake, not to cross post. Thanks for the info on what a servo is, it was a real eye opener.
