Bedini SG style motor (mechanical components)

thingiverse

Here is a simple and quick way to print a Bedini SG motor model. You'll need some extra parts for a successful assembly of this kit. Get 2 x Ball bearings, 15 x 10 x 4 mm (typical outer wheel bearing of front axle of an Axial RC model). You can find these bearings at your local RC store. You'll also need 22 x Screws, 3 x 12 mm (special thread for plastic). These screws are used on Axial RC cars, so you should be able to find them in your local RC store. To complete the motor, you'll need 24 neodymium magnets, 8mm in diameter and 5mm high. You'll only need 8 if you use the 8-magnet rotor. You'll also need some welding rods for the iron core of the coil. The coil requires 250m of 0.2mm magnet wire and 250m of 0.3mm magnet wire. To build the electronic circuit, you'll need to find the necessary components online. The parts that need to be printed more than once are: * 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 mounting_plate.stl. Place the center_rod.stl in the middle hole of rotor_xx_magnets.stl, then screw on the hubs. Add the magnets (you may need to grind the holes with a Dremel to fit them properly). Next, 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 connector.st (connects the 2 rotor stands) and the second rotor stand. The rubber_feet.stl will be glued to the lower side of the mounting plate. Add your bedini circuit and start the motor!
