as an aluminum alloy rotor 72 may have a plurality of high energy permanent magnets 76 fixedly mounted thereon or therein in selected positions as shown by example in fig3 magnets 76 may be linear in shape with a north magnetic pole north 76 at one end of each and a south magnetic pole south 76 at the opposing end of each magnet 76 the north 76 poles may be positioned for leading the south 76 poles in the direction of rotation of rotor 72 as is shown however the reverse may be used equally as well magnets 76 may be arranged as shown in angularly separated radial rows 78 shown by center lines in a spoke like arrangement around rotor 72 and with magnetic poles of magnets 76 radially aligned as shown in fig3 magnets 76 may be linear in shape as shown or may be circumferentially curved magnet segments magnets 76 are illustrated in one radial row in fig3 but it should be realized that similar sets of magnets 76 would be positioned on all of the rows 78 and more or less of the magnets per row and the number of radial rows may be adjusted stator 82 shown in fig4 may have a disc shaped rigid support structure 84 fixedly secured at points.
