hello I’m from the Etechnology team #8267 and we have an engine that we can’t find anywhere, we want to know if it’s allowed by the FIRST rules, we searched by serial number and no result
engine photos:
It’s a Denso Throttle motor!. While legal, they aren’t the best option on the market currently.

Yes, you’ll see it called a “throttle motor”. They came in the KOP for many years (might still, haven’t seen the KOP in a few years now). If you look in the manual at rule R501, it’s legal under the category “Current/former KOP automotive motors”.
Though I’ll agree they’re not really good for anything in FRC. At 18 Watts they’re going to struggle to move just about anything.

we will use for the claw will it work?
Depends what kind of claw, how you’re gearing it, and what you’re using it for.
Will it work better than a servo? Probably.
Will it work as good as a BAG motor or a NEO motor? Probably not.
Personally, If I was building a claw mechanism for this years FRC game, I would not recommend the Denso throttle motor (that said, I also wouldn’t actually build a claw mechanism for this years game, so take that with a grain of salt)

To put it in perspective, FIRST has provided motor specs in the past (Google turned up 2016’s here). The Denso Throttle Motor is an 18W motor with a free speed of 5300 RPM and a stall torque of 18.4 oz-in. Can you make that work with an appropriate gear reduction, meeting your force and speed requirements for the mechanism?
In my experience, it’s actually easier to use something like a NEO550 in this situation. It’s much more powerful (and weighs significantly less!), which means you can gear it so that it’s both faster and stronger than you need, then tone it down with software to find the sweet spot.

For reference, the Denso Throttle Motor is slightly less powerful than the FTC-legal motors: the REV Robotics HD Hex Motor, the Modern Robotics 12VDC Motor (also used by GoBilda), and the TETRIX MAX TorqueNADO Motor.
manufacturer | RPM | newton-meters
---------------|------|--------------
Denso | 5300 | 0.13
REV | 5960 | 0.18
Modern Robotics| 5900 | 0.19
Tetrix | 5920 | 0.17

Does anyone know the torque for this engine?
Check the two previous posts - both of them have the torque output of the motor clearly listed, each in different units.

hello, previously in my last post I talked about this engine, does anyone know what its torque would be? we know that it is a KOP engine, (which although it is not very biom it is what we have for an adequate weight)
Product Specifications:
| Voltage | 12V DC |
|---|---|
| Free Speed | 5300 RPM |
| Free Current | 0.4A |
| Stall Torque | 18 oz-in |
| Stall Current | 7A |
| Max Power | 18 W |
| Length | 3.4 in |
| Weight (lbs) | 0.5 |

Wow, I never looked at the specs that carefully before… at 18 oz-in, or 0.127 N-m, it’s basically weaker than any other FIRST-legal motor besides Servos. It works out to around 5% the torque (at the same RPM) as a CIM motor. Even FTC motors outperform these things.
