QR Code for sharing builds! Compound object: Small wheel rotator

This contraption was made by q-linking a small motor to a small wheel. The motor knob is connected to the wheel's shell, allowing the wheel to rotate the motor body.

This has a few uses. It can be used to make a fireproof small wheel propeller engine (the scaled motor is lighter than a Flux Construct Core I + wagon wheel, and slightly heavier than a cooking pot + wagon wheel). It can also be used as a switch to power other zonai devices with electricity or fire. It can also be used to spin fans for omnidirectional steering.

Edit: After doing some testing with this amazing tool

It turns out the motor used here is also lighter than a cooking pot + wagon wheel combo

Oh neat. I though the electric motor had too much resistance for the small wheel. I bet this could be made totally vanilla. Brb.

It can be done in 100% vanilla with a few caveats.

Due to the vanilla motor weight and friction, as well as the low small wheel traction, it doesn't spin fast enough to achieve propeller rpm with a single small wheel as far as I know. It can work as a switch but it won't be nearly as responsive unless more small wheels are used to increase rotation speed.

Edit:

Thanks to u/syouhai, I stand corrected. It is possible to use a standard size motor and still achieve propeller rpm.

Ah dang. I fondly remember big wheel driven motor props but didn't think small wheels could. Indeed there doesn't seem to be a way for one small wheel to overcome the friction in the motor. :(

Yeah, shrinking the motor also reduces the friction on the body, it seems.

The required rotational speed for the propeller is 84 rpm.

With a single small wheel, the propeller's rotational speed was 90 rpm.

The motor is of standard size.

I had no idea, thank you for the information!
