| ROTORSET-1
|
| |
Matched set of two 8-inch diameter steel rotor disks for use in dual-rotor axial-flux permanent-magnet alternators. Includes one ROTORDISK-1TH with 4 threaded jack-screw holes, and one ROTORDISK-1 without the threaded jack-screw holes. Designed to match up with our MAGSET-1 magnets and AFPMAS-1 stator.
For a minimal-cost, low-power alternator, use the ROTORDISK-1 only for a single-rotor design with one set of 16 magnets.
For more power, add a ROTORDISK-1TH on the other side of the stator. You need one of the rotor disks to have the threaded jack-screw holes, like ROTORDISK-1TH has, in order to assemble and disassemble the alternator without destroying things, because the magnets have enormous force.
For even more power, add another set of 16 magnets to the second rotor disk, for a total of 32 magnets (2 MAGSET-1 sets).
The 4 threaded jack-screw holes use standard 1/4-20 thread screws (not-included). Use the screws to lower the two rotors together, then remove the screws. Re-insert the screws to jack the rotors apart for disassembly. If the 16 magnets are equally spaced around the disk, and one magnet is alligned with the shaft key, then the 4 jack-screw holes are positioned such that the jack screws will drive between magnets against the ROTORDISK-1, which doesn't have the threaded holes.
The three holes surrounding the 1/2-inch keyed center hole are for fixing the rotor to a hub/rotor separator. The three holes may not be needed if shaft keys and collars are used to hold the rotors in place, but some sort of separator is needed for dual-rotor construction. If the hub/separator has a set screw or shaft key, the rotor/rotors can be fixed to the hub/separator with the 3 screw holes, and key slots on the rotor/rotors need not be used. |
