Slide 044 of 176

In Phase 2
• First on the list is to assemble a rotor of neodymium magnets onto the shaft.
• Second on the list is to insert the rotor through the bearings securely into the disassembled wooden panels.
• And third is to reattach the wood panels back onto the wood base blocks.

Neodymium magnets

Neodymium Magnets
(Phase 2 Parts)
• We will need no windings on the rotor of the S.H.O. Drive. Instead the rotor of the S.H.O. Drive will be built using very strong magnets.
• These magnets are an alloy of three atomic elements:
• Neodymium (or Nd) (the 60th atomic element)
• Boron (or B) (the 5th atomic element)
• Iron (or Fe) (the 26th atomic element)

Neodymium Magnets
(Phase 2 Parts)
• These Neodymium magnets are from Magnet4less.com and are pound-for-pound some of the strongest permanent magnets that you yourself can buy on the market today.
• These are often used in making wind turbine generators.

Neodymium Magnets
(Phase 2 Parts)
• Because these permanent magnets possess a stronger magnetic field, they will exert stronger magnetic forces on currents in S.H.O. coil.
• In turn, the current in the wires will be able to exert stronger magnetic forces on these permanent magnets.

Assembling the magnet rotor stack

Securing the Shaft
(Protocols)
• To secure the shaft into place, I will thread some extra square nuts temporarily onto the shaft and clamp them down onto the Black & Decker Workmate with the Bessey XM7 3-Inch Metal Spring Clamp that I obtained from inside a Woodcraft store.

Magnetic Pole Detector
(Measuring Equipment)
• Before I attempt to attach the magnets to the rotor, I will identify the north pole of each magnet with a Magnetic Pole Detector that I purchased from Magnet4Less.com

Magnetic Rotor
(Assembly)
• 20 Large Neodymium magnets with dimensions of 3/2” x 3/4” x 1/2” (or about 38mm x 19mm x 13mm) will be stacked like Jenga blocks to form the rotor.
• 8 Small Neodymium magnets with dimensions of 3/4” x 1/4” x 1/2” (or about 19mm x 6mm x 13mm) will be stacked in between the large Neodymium magnets.
• Together these will form a flush fit around the 3/2”x1”x1” (or about 38mm x 25mm x 25mm) square nut assembly, resulting in a magnetic rotor assembly measuring 6” (or about 150mm) long with square poles faces measuring 3/2” (or 38mm) a side.

Inserting the rotor

Wood Panels
(Disassembly)
• I will unscrew the hinges off of the wood panels, enabling insertion of the shaft and bearings into the panel holes.

Bearings
(Phase 2 Parts)
• I ordered shielded ball bearings from VXB at Amazon.com. These bearings are rated as having electric motor quality and will carry the weight of the shaft.
• These bearings should fit snuggly into the holes carved into the wood panels.

Inserting the Rotor
(Assembly)
• After that, I will insert the rotor assembly, through the installed bearings.
• Then I will fasten the wood panels back onto to the base blocks.
