Greetings, I am developing a robot project, and I was quite interested in these twin / double Tamiya motors. Does anyone have detailed information on them (i.e. a datasheet)? Can I buy them with encoders?
What do the multiple gear settings mean, that they come in these different options, or that I can switch the gearing by myself? It’s not something sophisticated and automatic like a car gearbox, right?..
I need something around 5W power and 350 rpm. My robot will probably look like one of these 1-litre sumo fighters, but I’m not into competition…
Hi, thanks for answering!
Only now I understood that the double and twin motors are not the same thing…
I need double motors with the gearboxes ending in right-angle transmission, to make a small differential-drive robot, just exactly as this Tamiya double motor. Unfortunately, it seems to be below the power I wanted.
This other RB-Tam-02 Tamiya with nearly 3W seems more like it. But can I change the axle to make two “mirror” motors for differential drive?
The calculator is neat! It would be nice if it had mNm as another option for torque. :]
Not much information is available in digital format. What data in specific do you require?
Although the gearboxes are not available with wheel encoders, the encoders can be purchased seperately here:
robotshop.ca/home/products/robot-parts/sensors/encoder-disks/index.html
In theory, most of the wheel encoders that use disks should work well for you.
Depending on the way you assemble the gearboxes, they provide different gear ratios. The included manual describes how to do this.
If you need to determine the motor/wheel combination for your robot, we invite you to try the Drive Motor Sizing Tool in the RobotShop Learning Center.
Hi nwerneck,
Did you consider the Tamiya universal gearbox? Two could be mounted side by side and provide significant torque. The Solarbotics right angle motors may be agood choice as well.
Your feedback on the calculator is appreciated. We chose the three most popular units (Nm, kg-cm and oz-in). To convert Nm to mNm, multiply by 1000
.
You determine the position of the axle on the RB-Tam-02 (you assemble the entire motor actually), so you can have it stick out from one side only if you want. If the shaft is too long, use a hacksaw or bandsaw to cut it down to size.
