SSC32 and DC Motors

I wasn’t really sure where to post this but I have an idea for a project I want to work on involving high RPM (3200rpm+) DC motors, whats the easiest way to attach DC motors to the SSC32? The end goal that I want is that I can set the speed of these motors programmatically from my laptop.

I have a couple of DC motors that I found at Radio Shack the other day that I’d like to get working with the SSC32 servo controller, do I have to buy a Sabretooth motor controller and interface that with the SSC32 servo controller to be able to have variable speeds on the DC motors?
Or what would be the best way to do this?

If you need high rpm, then the easiest thing to do is get a servo, remove the gearing on top, and connect to the motor output shaft.

I think he already has motors in hand that he wants to use, Zoomkat.

I’d say that the easiest way would be what you have already stated. Get a Sabertooth motor controller that can provide enough current for your motors and the SSC-32 can control the Sabertooth.

Alright cool, so I was on the right track. Thanks Fish! :slight_smile:

Wow! Somebody obviously has $$$ to burn just to control a “Radio Shack” motor! :unamused:

shrug Comp sci major, and I have some money to burn. So I turn to robotics kits for a hobby nothing wrong with helping the economy, amiright? :smiley:

Edit: as for the radio shack motors, I was in there to buy some a new precision screwdriver set and I just saw em, figured I’d pick em up and do something with em. (got an idea for a project in my head, just not sure how to implement it just yet :stuck_out_tongue: )

“Money to burn” implies there is a cheaper way. However there is no reason to believe a servo board could actually power the radio shack motor. It could have a 5 amp stall current. The Sabertooth may be the only way to go.

I would consider a $5 or $12 solution cheaper than a $60 solution. The poster says he has $$$ to burn, so I’ll consider this as a “stimulus” project too. :smiley:

This discussion is pointless since we don’t know if the radio shack motor is a 100mW motor or a 25watt Mabuchi RS-540 motor… :unamused:

I don’t think it is pointless. Per the first paragraph in the origional post, the person wants to control the speed/direction of a “high RPM (3200rpm+) DC motor”. I don’t know the free running speed of the motor in a servo, but it probably is 3200rpm+. I’m just suggesting the person might want to get a HS-422 servo (or similar) and disassemble it like below, and also remove the motor to use to direct drive something. Do note that I have no involvement other than passing on another possible alternative.

Welp, you guys got me to be too embarrassed. :blush:
I returned the motor.

Btw: Here is a list from their online store. You can see the prices do not exceed $6 on motors. radioshack.com/family/index. … 271&s=null
