I’m looking at the Banebots CIM motor (RB-Ban-71). I have a couple questions. what is the duty cycle? can it be connected to an encoder or pot to provide position and direction feedback to a controller for a servo setup?
what is the duty cycle?
Unfortunately that’s not included in the CIM spec sheet, so you can assume it’s around 25% (average for brushed DC motors)
Can it be connected to an encoder or pot to provide position and direction feedback to a controller for a servo setup?
Unfortunately there’s no rear shaft to mount an encoder, so no clear way to convert it to be used as the basis of a servo.
ok, this is where my knowledge becomes limited so please forgive me if its a stupid question…lol. is it possible to connect it to the main shaft?
Yes, but you would need to find a way to keep part of the encoder’s housing stationary while the inner part of the encoder rotates with the shaft.
You will also find that most encoders are made to be used with small diameter shafts, so you might have a bit of a search ahead of you (or be prepared to adapt or create one).
Actually the motor would be going into one of banebotts gearboxes which would have a .50 dia. shaft. You guys sell an encoder box with encoder product #RB-And 145 which I believe is made to connect to the banebots gearboxes with .50 inch shaft. I was able to open the “documentation” link on your product page for some reason. Can you take a look and please give me your opinion.
I am planning connecting this encoder as feedback to one the Roboteq Controllers. I haven’t decided which one yet. I know the CIM motor is brushed so it will be a brushed motor controller. I guess my concern would be is whether on not the controller can except the encoder and that the leads from the encoder all have a place to connect to on the controller. Do you any thoughts on this?Thanks
Your logic seems to be sound. Note that the CIM motor is quite high current, and only some DC brushed controllers accept encoder input.
thanks for saying that. it’s nice to know i’m on the rite path. I missed typed in my last post. I meant to say i’m NOT able to open the “documentation” link on your product page for the encoder. I wanted to look at the info talking about the current. can you possibly make sure that the link is ok? I don’t have a problem opening other doc. links on your site. i’m running windows 8.1 if that helps.
We checked the download and it seems to work. The file contained is a .STEP file which needs to be opened using CAD software. There is no additional documentation unfortunately. The sensor will consume very low current.
