Abstract

PURPOSE:To short-circuit a magnetic path by separating the end section of a rotor, where a non-magnetic rotary shaft is penetrated through the central section of a magnetic board and secured thereto, from the magnetic path and establishing a closed magnetic path individually between the stators. CONSTITUTION:Front face of the magnetic pole of a permanent magnet 1 coincides with the axis of rotary shaft while the direction of flux is in parallel with the rotary shaft, and a magnetic board 2 is magnetized by the flux. Contrary to a conventional rotor, the opposite ends of the magnetized board 2 have same polarity. Consequently, the lines of magnetic force can not pass through the magnetic board 2, i.e., the rotor, and internally distributed lines of magnetic force are absorbed and converged resulting in complete polarization at the end portions. The flux is deflected by 90 deg. and split into right and left portions thus forming a split magnetic path short circuit between stators having lowest magnetic resistance. By such arrangement, flux does not pass through the rotor and a magnetic short circuit path for such as a transformer can be provided to the stator, resulting in considerable shortening of overall magnetic path.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to both electric motors and generators that utilize permanent magnets. The magnetic circuit of a normal rotating machine is established by passing through the rotor and making half a circuit around the circular path of individual electrons provided outside the circumference, and the shortest is the diameter of the rotor plus half the circumference 2r + π
This is more than five times the γ radius, and it is structurally impossible to shorten it below this value.

Shortening the magnetic path is a necessary condition for increasing magnetic utilization efficiency.

If the magnetic path is halved, the magnetic force will be four times as great, and the functionality of magnetic rotating machines will be greatly improved.

The present invention aims to shorten the above-mentioned structural limitations through a structure.

To explain with a diagram, the magnetic pole front of the permanent magnet 1 coincides with the direction of the rotation axis, and the direction of the magnetic flux is also parallel to the rotation axis. This magnetic flux does not magnetize the magnetic plate 2, and both ends of the magnetized magnetic plate 2 rotate normally. Unlike the magnetic field, it becomes a polarized magnetic end.

Therefore, the lines of magnetic force cannot pass through the magnetic plate 2, that is, the rotor, and the lines of magnetic force distributed inside are absorbed and collected, and the polarity is completely polarized at the end. The direction of the magnetic flux is bent by 90 degrees and divided into left and right magnetic ends with the center as a boundary, and a divided magnetic path shortening circuit is formed between the stators with the lowest magnetic path resistance.

Therefore, the magnetic flux does not pass through the rotor, and the stator has a short magnetic path similar to that of a transformer, making it possible to significantly shorten the entire magnetic path. Figure 6 shows this situation.

It is also possible to make the radius a little less than three times the radius, or half the radius of the normal type, compared to just over five times the radius of the normal type.

FIG. 7.8 shows a device for timing pulse starting in the case of an electric motor. The laser diodes 6-a and 6-b constantly emit light and provide the light input to the light-receiving elements 7-a and 7-b.

When the rotor rotates and blocks the light path, the light receiving element 7-
A cuts off the input, transmits a sudden change in current to the electronic circuit, and as a result, the rotor and the coil are excited in the opposite polarity direction and are attracted and rotated, resulting in the state shown in Figure 8, and the light of 6-b is generated. block the road. 7-b, whose optical input is cut off, loses its input and is reversed to the same polarity as 7-a, and the rotor receives a repulsive force and leaves the strong magnetic field of the stator, returning to its initial state. It returns to rotational motion.

To take full advantage of the efforts of this invention, the strongest permanent magnets available today are used.

If a neodymium iron magnet is used to form a multi-pole multi-connection composite type (not shown in Figure 9) on a rotating shaft, a powerful brushless current motor that saves power can be expected. Also, if used in a generator, it becomes possible to make it smaller and higher output.
