Author Topic: need dimensions for GM13a motor (Read 1497 times)

I'm trying to CAD this motor up, but the only dimensions I can find are:

Quote

Length (mm):     33.10 mm
Width (mm):     12.00 mm
Height (mm):     10.00 mm

Somewhat useless, it doesn't mention the details, like shaft length/diameter, etc . . . anyone got more info?

These may be the same as the ant weight sized motors sold at robot marketplace. let me check.

Hmmmm I used to own one of these years ago . . . shaft seems 2x longer than I remember . . . can anyone verify these values?

this is the actual motor but it has no dimensions listed http://www.robotmarketplace.com/products/0-GM13A.html.

Here is an alternative with dimensions and similar performance specs http://www.pololu.com/catalog/product/997

I find phoning the company or emailing them with questions helps, they are generally very quick to respond.

coming back to this motor . . . I see two places selling it, Solarbotics:
http://www.solarbotics.com/products/gm13a/
and Pololu:
http://www.pololu.com/catalog/product/1097

They each list very different torque and rpm specs. Anyone verified the torque/rpm?

(robotmarketplace gets the specs from solarbotics)
