  • each magnet could be electro-magnet types as where, for example, the dynamomagnetic machine is quite large.
  • each magnet is mounted with its poles skewed and aligned at an angle A with respect to a radial from axis 15 that passes centrally through the magnet midway between its two poles. With this orientation it is seen that each magnet has its poles aligned parallel with a radial from axis 15, with the magnet center offset by a distance S.
  • the stator 11 also has a set of permanent magnets 20 mounted thereto in axial alignment with and closely adjacent to the path of rotation of the annular array of rotor magnets 13. For clarity of illustration only two stator magnets 20 have been illustrated; however, a larger number such as 6 to 8 is preferably employed.

  • the angle A drawn is smaller, an angle A of approximately 30° has been found to be optimum. Lesser angles, such as some 20° result in lesser power (and speed) being developed as the forces of repulsion become more radially directed. Greater angles, such as some 40° also produce less power with lessened field confrontation.

  • the face of the rotor magnet 13 proximal to the stator magnet confronts the adjacent face of the stator magnet at an angle so as to create a unidirectionally rotary motion of the rotor with respect to the stator.
  • Fig. 3a the approach of the magnet 13 to its point of perigee with magnet 20 is- resisted since adjacent poles are proximally positioned in their mountings.
  • this confrontation is to a lesser spatial degree than that of Fig. 3c were the rotor to be attempting to rotate in the direction opposite to the arrow illustrated in that figure.

  • the rotor is seen to have a set of rotor magnets 44 rigidly mounted thereto with their poles oriented as shown at a skewed angle B which preferably in in the order of some 30".
  • the stator is seen to have a set of stator magnets 45 rigidly mounted thereto with their poles located as shown at a skewed angle such that passage of the rotor magnets thereby brings them in a mutually parallel relationship as their centers are aligned at perigee.
  • the machine is seen to have strips of magnetic insulation material 46 mounted to magnets 45 so as to overlay their south poles. Though other suitable magnetic insulation materials are commercially available in mesh form, rubber has been found by applicant to provide good magnetic insulation in this application. in operation the dynamomagentic machine 40 operates in a mode very similar to that previously described in conjunction with the explanation of Figs. 1-3.
  • the magnetic insulation 46 will lessen the forces of repulsion as the south poles of the rotor magnets approach the south poles of the stator magnets. At the same time, the insulation will not tend to lessen the forces of repulsion provided as the north poles of the rotors pass the north poles of the stator magnets since the insulation does not extend over the north poles of the stator magnets.
  • FIG. 5 Another technique employed in maximizing the driving forces and resultant power of dynamomagnetic machines is illustrated in that machine shown in Fig. 5 whose operation is sequentially shown in Figs. 6a-6e.
  • the stator 50 is provided with stator magnets 51 in an annular array about an unshown stator axis, similar to the other figures.
  • the north pole of the stator magnet shown is seen to be located adjacent the rotor 53 rather than on one of the ends of the magnets, as in Fig. 4.
  • the rotor 53 is seen to have a set of rotor magnets 54 that are mounted to the rotor for pivotable movement about a pivot 55 towards and away from the magnets of the stator 50. Movement is controlled by a camming mechanism that includes a cam follower 56 that is mounted on the end of an arm 57 for pivotable movement about a pivot axis 58.
  • An end 57* of the arm is positioned so as to support that portion of the magnet
  • the stator is provided with an endless camming surface 59 that is shaped to cam the cam follower 56 in its revolution about the stator and rotor common axes in producing the desired pivotal motion.
  • Figs. 6a-6e sequentially illustrate the pivotal movement of one rotor magnet 54 as it passes one stator magnet 51.
  • Fig. 6a it is seen that as the rotor magnet 54 approaches the stator magnet its south pole is drawn toward the north pole of the rotor magnet. It is also seen that no camming action is effected until the trailing edge of the rotor magnet 54 has reached the midway point along the rotor magnet. At this point the camming mechanism causes the rotor magnet 54 to pivot so that its trailing north pole is forced into close proximity with the north pole of the stator magnet 51. An angle of about 60° is finally achieved between the two magnets which is maintained, as shown in Figs.
  • Figs. 7 and 7a jointly illustrate another dynamomagnetic machine which utilizes rotating magnets to an advantage in maximizing the effects of forces generated between rotor and stator sets of magnets.

  • the rotor also has a conical gear 75 that projects outwardly from the face 74 whose apex is located along a common stator and rotor axis.
  • the stator 72 is also seen to have an annular array of stator magnets 77 that are seen to be larger and stronger than the rotor magnet 73. The mounting details of the stator magnets is omitted in Fig.

  • a truncated conical gear 86 is mounted to the end of each axle 80 located closest to the axis 85 in mesh with the rotor gear 75.
  • stator gears 86 which in turn cause the stator magnets 77 to rotate continuously within the openings 79.
  • the rotary positions of the stator magnets is selected such as to maximize the rotor driving forces generated between the rotor and stator magnets doing their mutual passages.
  • approach repulsion is diminished as' ' much as possible by the poles of the rotor magnets 73 as they approach each of the stator magnets 77 and maximized upon departure.
  • the magnets of the rotor and stator face each other and are arranged along rotor and stator planes as opposed to the annular positions of the stator and rotor magnets in the previously described embodiments.

  • magnetic insulation is again utilized as a means for maximizing the forces of repulsion between rotor and stator magnets in a desired direction of rotation.
  • the dynamomagnetic machine 90 is seen to have a rotor formed with a set of vanes or arms 91 that extend radially from a drive shaft 93. To the end of each vane is mounted a permanent magnet 92.

To outer surfaces of each of the tunnels 95. are mounted stator magnets 97 with their south poles shown located just at ____ the exits of the tunnels. With this configuration as the north poles of the rotor magnets approach the north poles of the stator repulsion is lessened to a substantial degree by the presence of the magnetic

Abstract

Une machine dynamomagnétique utilise des rangées annulaires d'aimants (13) montées sur un rotor (10) et un stator (11) de sorte que les forces magnétiques générées entre eux entraînent le rotor (10). Ceci peut être obtenu par des orientations spécifiques de montage des aimants, une réorientation cyclique des aimants ainsi que l'utilisation d'une isolation magnétique (96).
