Bedini SG style motor (mechanical components)

Here is a easy and fast to print model of an Bedini SG motor.

You have to get some additional parts for a successful assembly of this kit.

• 2 x Ball bearing 15 x 10 x 4 mm (typical outer wheel bearing of front axle of an Axial RC model). You should get these bearings at your local RC Store.
• 22 x Screw 3 x 12 mm (special thread for plastic). Also used on Axial RC cars, so you should find these screws also in your local RC store.
• 24 neodynum magnets 8mm in diameter, 5mm in hight (you only need 8 if you use the 8 magnet rotor).
• some welding rods for the iron core of the coil
• 250m of 0.2mm magnet wire and 250m of 0.3mm magnet wire
• the components to built the elctronic circuit (can be found on Internet)

these parts have to print more than once:

2 x rotor_stand.stl
2 x connector.stl
4 x rubber_feet.stl

Assembly tips:

glue together the upper and lower part of the coil. Complete your coil by adding the iron core and the coil wires. Screw your finished coil to the part mounting_plate.stl.
Place the part center_rod.stl in the midlle hole of part rotor_xx_magnets.stl then screw on the hubs. Also add the magnets (maybe you have to grind the holes with a Dremel to fit the magnets properly)
After that you have to press the ball bearings into the parts rotor-stand.stl. Screw one rotor_stand.stl to the mounting plate (bearing faces towards the rotor). Add the rotor. Screw on the parts connector.st (connects the 2 rotor stands) and the second rotor stand.
The parts rubber_feet.stl will be glued to the lower side of the mounting plate.
Add your bedini circuit and start the motor!!

Have fun with this kit!!!
