Motor advice

Hello,
I have a project that needs to utilize a motor. The
motor will need to move a 5 pound object (technically
the motor will turn a disc with which the 5 pound
object is placed upon). My question: Does anyone
know of a fairly inexpensive motor that has enough
power to accomplish this and be easily interfaceable
with the BS2?
Thanks for any help you could offer.
Best of Regards,
Todd

Hi Todd-
You'll need to offer more information -
Nearly any gear motor or motor + pulley, can turn 5 pounds.
What are the other characteristics you require:
type (stepper, servo, permanent magnet, brushed, brushless)
voltage (AC single phase/3-phase, DC),
amperage (amps or milliamps),
mounting (front, rear, threaded/bolt-on)
speed (rpm), etc.

Thanks for your further inquery. My general
description is indicative of my lack of experience in
BS2 / Motor apps. Your comments are certainly valid
and I will try to answer them:
YOUR QUESTION: What are the other characteristics you
require:type (stepper, servo, permanent magnet,
brushed, brushless)
ANSWER: I think servos have a limited range of
movement, therefore a motor that can turn until a
conditional statement stops it seems ideal. Further,
I have a photocell that will indicate when to stop the
motor, thus tracking the location of where the motor
has turned to is not needed. As for the construction
(permanent magnet, brushed), I don't know. I'm
looking for something that will turn slowly and won't
have a coasting effect (ie., when I want it to stop,
it stops). Could you tell me which one you recommend?
YOUR QUESTION: voltage (AC single phase/3-phase, DC),
amperage (amps or milliamps),mounting (front, rear,
threaded/bolt-on)speed (rpm), etc.
ANSWER: Due to my limited expertise I prefer to work
with low voltage and DC, if possible. As for the
mounting, it will be under a disc that's hooked to the
shaft of the motor thus turning the disc (I'm not
really sure what kind of mounting that would be, hence
the description). RPM's would be low, I want a slow
turn and a fairly quick stop.
Once again Bruce, thanks for your help. I have
observed your participation in this group and your
talent for helping others is admirable and certainly
most appreciated.
Best of Regards,
Todd A. Botner

DC steppers are both easy to operate, and inexpensive to obtain, as surplus
items. Geared steppers are available as well. What sort of price range did
you have in mind, and is this a one-shot deal, or for production ?

Will this be battery operated or is access to line voltage available -
whether used at the platform or not ?

This is a one-shot deal.
QUESTION: Will this be battery operated or is access
to line voltage available - whether used at the
platform or not ?
ANSWER: I would prefer to be battery operated,
however, if there are too many obstacles or
difficulties I would have no problem using line
voltage.
Here's the application Bruce, would love to hear your
comments:
I have a couple of plants that, b/c of my busy
schedule, don't maintain very well. I'm placing the
plant on a disc with a photocell near the base of the
plant. Depending on the amount of light the plant
needs, it will cycle in and out of the sunlight as
needed (hence the need for the motor). Depending on
the intensity of light I will have the plant stay out
a longer (or shorter) amount of time, this will
account for cloudy and seasonal variations. Depending
on the needs of the plants moisture level, I am
utilizing a water pump to water the soil as well. I
am writing the code for a BS2 to control everything.
Really I don't think this is a complex project, just
haven't worked with Stamp / Motor integration before.
However, the whole idea is on the drawing board, so I
may be speaking too soon.
Thanks again, Bruce.
Regards,
Todd

That's your choice entirely, since you're paying for the batteries : )

Nope, not at all. Shoot over here [noparse][[/noparse] http://www.elabinc.com/ ] to E-Labs and
request their new CD-ROM. Then, when you get it, contact me offlist, and I'll
load you up with web pointers for decent surplus stepper motors. Once you
get that all sorted out, we can go back on list as you assemble it. Sound
like a plan ?

Sounds great. I just ordered the CD and you can send
those links whenever you like, OR I'll contact you
once the CD arrives.
Thanks again for your invaluable advice.
Regards,
Todd
