Published on Dec 5, 2014 Home made v12 solenoid motor - 2,700rpm maximum, when its in a good mood. ..............................................................................................................................................Technical details: 60 degree V12 - runs on 24v dc fixed - cylinder bore 8mm, Stroke 10mm, theoretical total displacement is just 6cc, sealed roller bearings 684zz (4x9x4mm) are used for the main and big end bearings, the flywheel bearings are larger (4x13x5mm) to handle the weight of the flywheel (900g), the crankshaft is made up of one hundred and forty individual parts, and is counterweighted to balance the rotational mass (the reciprocating mass cancels itself out in the v12 design), the flywheel is an old drill chuck, the tachometer pickup is on the rear of the timing / distributor shaft, solenoid model used: SOLEN 121E16530, these solenoids have built in flyback diodes, the switching transistors are 2N3055. The engine is running as a 2 stroke here but can also run as a 4 stroke at the flick of a switch. The panel meters and digital tachometer are available on ebay. Nuts, bolts, bearings, wiring, solenoids, 4mm brass rod & timing gear all obtained from ebay. The timing chain and sprockets are Meccano, marked Fabrique en Angleterre (Made in England), like the engine they are on. Total weight of engine = 6kg approx. Built with basic tools, in a shed, using scrap aluminium & wood, Enjoy :)
