There is a chance that it's quite the opposite! We estimate its energy conversion efficiency not to exceed 20%, which is about one third of what is standard for regular electric motors. This solenoid engine is about beauty and simplicity. 

The parts are compatible with similar brick items and the LEGO® Group of companies does not sponsor, authorize or endorse this site.

Being a reversible machine, you can generate pulses of electricity with it if there is something at your disposal to spin the crankshaft.

The torque and power of this motor is enough to run beautiful demonstrations but not enough to damage any plastic parts.

We hope you will! The coils can be used for simple builds like a crane with an electromagnet or for a Kibble balance. Here is the link with the instructions and a list of parts for the Kibble balance.

Good question! This part can be used in any project where you need to save and store rotational energy!
