Solenoid motor

thingiverse

This is a functional model of solenoid engine. I already made one and for now it is working fine. I am sharing my SolidWorks 2014 files so if you want you can adjust the model as you see fit. The following hardware will be needed to assemble the motor: 6mm balls for the flywheel ( not necessary, motor should work without them ) Coil wire ( I used 1mm wire ) 2x 8x40 metal rod 2x Rectifier diode 1x Capacitor 1000u/25V 2x Micro roller switch - you can find it on ebay : 10Pcs KW12-3 Micro Roller Lever Arm Normally Open Close Limit Switch Assembly instructions : Print all necessary parts. 2x Conecting_rod 2x Piston_onnecting_rod 2x Coil_holder1 2x Coil_holder2 1x Commutator 2x Piston_holder 1x Conecting_rod_top 2x Wall 1x Crankshaft 1x Ignition_wheel 1x Flywheel ( I suggest using 30% honeycomb infill , supports only if the are needed ) Glue together Coil holder1 and Coil holder2 parts with acetone. Then you will need to wound coils on them. Connect the metal rod with piston_holders ( I drilled 2.5 mm hole to the pistons and used piece of 2.5mm welding wire as a cotter pins, but making a thread on the end of the rods will works as well I think. If someone find better way how to attach piston to the piston holder feel free to let me know ) Connect piston_rods with piston holders and the crankshaft. Everything should move freely so before you do that use some sandpaper and finish the parts. Attach both coil on the top_conecting_rod, insert the pistons to the holes in coil holders (assembled with crankshaft and piston rods ). Then you can put everything together ( Walls to each side, crankshaft should fit trough the holes ) Glue on the flywheel to crankshaft and commutator to the opposite wall ( Insert the metal balls to flywheel before attaching it if you have them ) Insert switches to the commutator and attach ignition_wheel. The you need to solder everything down. Don`t forget to connect diodes to the coils. (I will add the electric scheme later ) Then you must find the right spot for ignitions by turning the ignition_wheel. ( This is the hardest part. I had to print many of these ignition_wheels to get it working right ). All done. If all is properly connected motor should run. I needed at least 15V (3A) to get it running. Good luck ! :) I welcome any suggestions how to make this model better so feel free to email me ,send PM or leave a comment. Thanks!
