planetary gears, interesting.


Recommended Posts

i was googleing for smt/d LED lights to use in my drill when somehow i stumbled upon this video and i learned something new about the technology (same applies to automotive tech)...

interesting how the gears reduce the speed of the motor... which makes sense since a DC motor spins upwards of 10,000 RPM while a fast drills output RPMs are around 2,500-3,000 RPM. and here i was thinking that a faster RPM motor would give me better results... i was actually going to look for a faster spinning motor for my drill to install... actually for a brushless one with the same (or close enough) RPMs and torque... anyways...

just sharing.
