Micro Gearmotor - 900 RPM (6-12V) Product Help and Resources
Core Skill: Robotics
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.
See all skill levels
Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

Nice
it is a good gear motor and your sales team is great!! The other 2 motor came broken as well on the top part where you solder the wires to. I like it so I had to rig my wires another way onto it. I want to order a couple more at different RPM speed, but hesitant about the one end. Maybe you have an answer not sure. I also wanted a Rheostat/Pot. to go with this motor for control and your team did a nice job helping, but was the wrong one. Other than that I will continue to use sparkfun and recommend to others no worries, just wish we could get stable connectors on the gear motor box. I had to throw 2 away because it locked up on me as well, and only used for about 10min. Thank you
Thanks for the feedback. I've used these in a lot of robotics applications and have really enjoyed using them myself. On a rare occasion I have had some lock up on me too. If you have issues with your parts, please feel free to contact us. We'll do what we can to help!
Very capable little motor!
For the price this motor and gear train are a great value. All metal gears, lots of torque. Electrical contacts are very thin, so care must be taken in handling. The whole family of these motors is very capable, providing a lot of options when tinkering a design.

Extending the Shaft of the Microgear Motor
If you are looking for a way to extend the microgear motor's shaft to add an encoder, feel free to use the Shaft Coupler - 1/4" to 3mm [ https://www.sparkfun.com/products/12412 ]. You would just need to find a shaft length that is suitable for your project. Here's an example from ServoCity using a shaft coupler with a micro gearmotor => [ https://www.servocity.com/media/catalog/product/cache/1/image/438x280/602f0fa2c1f0d1ba5e241f914e856ff9/c/o/coupler_on_gearmotor_with_shafting.jpg ].
Please I need 2 of them, but just there is one in stock. When do you will have more of them in stock?
