8. Permanent magnets of stator

Stationary magnets can be made in the form of rectangles. The design of a possible implementation of the stationary permanent magnets is shown in Fig. 8.

Stationary magnets which provide levitation
Fig. 8

Here are shown the stationary permanent magnets placed in the part of the space between the disks, where is the most expediently to use the phenomenon of levitation. On passing through this sector of rotation, the cylindrical loads rise upward, due to influence of levitation, and are gradually shifting to the circle of minimum distance from the axis of rotation of disks (Rmin). During the whole time of this lifting is carried out complete compensation of the gravitational impact on the loads. I.e., the cylindrical loads, on passing through this sector of rotation, do not exert any (negative) influence on the magnitude of the net torque.

As a result of such impact levitation the net torque of the motor shaft is determined only by the sum of the torques which are created by the movable loads, during their passing through the another sectors, through the sectors into which their centers of gravity are linked by the unequal lever arms of rotation around the axis of the motor rotor. (That are the loads corresponding to the loads which have been designated in Fig. 2 by the symbols A4a13, A5a14, A6a15 and A7a16). In this case, the net torque of the motor shaft is provided by use only the kinetic energy of the gravitational field. The arising under such conditions rotatory impact, as it has been told earlier, we will call in future the "Initial rotatory force", unlike the "Additional rotatory force", which can be achieved by use other energy sources.

In Fig. 8 are shown several identical groups of the stationary magnets. Quantity of the stationary magnets under each of the cylindrical loads is equal to the total number of magnetic rings on the two adjacent loads, i.e., in our case - three (3 = 2 + 1). The lengths of the pole's surfaces of the stationary magnets, incoming in composition of such group, correspond to the lengths of the magnetic rings which are moving above them. To eliminate the mutual impact of the stationary magnets, located close to each other by their side walls, should be applied the known means of shielding magnetic fields[12], [13]. The height of the stationary magnets, the optimal shape of their surfaces, which are directed against the annular magnets of the movable loads and the length of air gaps between the counteractive magnets are subjected to elaboration during experimental testing.

The variant of execution of the stationary magnets which have been shown in Fig. 8 should not be considered as unique. Maybe instead of the few magnets, as it have been shown in Figures 5 and 8, it will be possible to apply a single stationary magnet of desired shape and of the corresponding magnetization. In any case, the choice of optimal variant of fulfilment of the stationary magnets and of means of their installation in the actual design should be implemented in coordination with the manufacturers of magnets.
