The disclosed embodiments concern a permanent magnet motor.
Work is conducted worldwide to find a simple and proper solution to the object of providing motion with lowest possible loss, with the origin of pull and push forces from magnets.
On YouTube, several solutions with permanent magnet motors can be found, which produce a rotational movement, e.g. as shown in US 2006273666 A1 and US 20100148610 A1. However, the solutions described there appear to loose substantial power during transition from forward and backward motion in the rotating system:
a) in that the magnets obtain unfortunate inclined positions,
b) in that the magnets must pass other magnets,
c) in that the magnets cannot perform what they are supposed to do, i.e. just push and pull without any unfortunate acceleration and retardation forces,
d) in that it is not possible to obtain a powerful 360 degrees tangential torque.
Prior art from US 2006273666 A1 shows reciprocating movements (107, 118) (126, 124), which alternatingly pull and push a piston rod (117) through two +− magnet disks (119a, 119b) attached to a rod, by a magnetic isolated intermediate plate (119). The forward and rearward movements of the magnet disks (118, 124) including rollers and rods (107, 126) will according to US 2006373666 A1 have to increase weight, but also increase the acceleration and the retardation forces at higher rotational speeds (for example 1500 o/min, which will be natural to the device). This produces 25 switching operations per second, which will become a large problem, with high vibrations even at low rotational speeds.
It seems that US 2006273666 A1 has chosen to solve this problem by applying alternative forces, such as:
Force, 1): pressurized air (109, 128)
Forge, 2): current from the mains (405a, 425a)
Force, 3): current from battery (307).
On basis of this, US 200627366 A1 is a hybrid. Impulse decays on (S1, 109) makes it doubtful whether the machine will operate at all, since there is no mechanical transmission from “drive shaft to the ignition system”. Compared to a gasoline motor/Otto motor, it has mechanical transmission from driving wheel to both cam shaft and distributor to prevent breakdown.
The disclosed permanent motor improves upon the prior art.
The particular effect obtained compared to the prior art, is that the permanent magnets of the device are attached along the periphery of inclined circular disks, which are balanced, thus lacking the large and disadvantageous acceleration and retardation forces experienced by the prior art. The principle of the device is more familiar to the rotating magnetic field in a three phase engine, which produces a powerful 360 degrees tangential torque, without the need for electricity or another form of incoming force from other units, which is the case of the device described in US 2006273666 A1.
The permanent magnet motor disclosed herein produces an outgoing rotational force without the need for assistance by electricity or another form of incoming force. The outgoing mechanical rotational force is provided by two independent rotating inclined disks with their bearings attached to a fixed hub, in a gusset/tooth engagement with a drive shaft. Around the periphery of the disks, there are mounted linear +/− permanent magnets in pairs. The push and pull forces from these magnets occur along the attachment circles. controlled by on/off-sectors in the form of arc shaped recesses in a screen amounted between the disks. The example illustrated by the drawing and described below, provides a pull sector (−) of about 90 degrees, and a diametrally located push sector (+) of about 90 degrees. In order to be able to provide a rotary field of 360, additional rotary fields at the two remaining diametral blind sectors, each exhibiting 90 degrees, must also be provided.
An example of a solution of a 360 degrees rotary field: the drive shaft is provided with another power unit with a screen, where all is rotated 90 degrees in relation to the first power unit. Hence, the two power units will together provide the device with a rotary field to the device of 360 degrees. Then, the two power units will together provide the device with a rotary field of 360 degrees, i.e. 4×90=360 degrees. In order to provide the device with even more torque, additional power units are attached to the drive shaft. Moreover, the structure of the device is suitable for mounting additional large permanent magnets to operate power generators, for electric operation of cars, propulsion to ships and airplanes, etc., without fuel, without noise and exhaust from combustion engine, without high weight, and without charging and environmental problems by battery operation. It should also be mentioned that solar energy is very area demanding. With respect to control of power requirement, including start and stop: An example of this is shown in the drawing, where fixed screens having circular on/off sector tracks for controlling magnet operation, also have a “unlockable” support to be turned around the center of the drive shaft. By turning the screen, the magnets will lose the rotary force for in the end to stop the device. By turning or lateral displacement of “parts of” screens, one must make sure that the fixed hub supporting inclined disks is not moved.
A cooling fan, flywheel and connecting element, e.g. for power generator and similar are illustrated. The mode of operation of the device can also be experienced by rotating the drive shaft. Then, it is possible to observe the reciprocating movement of the permanent magnets.
The inclined surfaces and the hub ensures that inclined disks rotate toward a smaller disk distance by magnet pulling, and diametrally larger disk distance by magnet pushing in the same direction of rotation, and with diametrally larger disk distance by magnet pushing in the same direction of rotation, and with inclined balanced disks, do together provide a practically vibration-free tangential rotary power, which tolerates high rotational speeds, and effect.
In further detail, the permanent magnet motor disclosed herein exhibits a number of permanent magnets, arranged on a rotary support, connected to a drive shaft which again is connected to a power generator or another device in need of driving force. The permanent magnet motor exhibits at least two power units in the form of a first power unit and a second power unit, mutually separated by a shielding plate, wherein each power unit exhibits
a first rotary disk and a second rotary disk opposite the first rotary disk, both attached displaceable on the drive shaft to co-rotate with the same, wherein
as stator plate is arranged between the first rotary disk and the second rotary disk, wherein each rotary disk further exhibits
a number of permanent magnet pairs consisting of a pull magnet and a push magnet, displaced radially and circumferentially in relation to the pulling magnet, said permanent magnet pairs being distributed at a constant mutual distance along the periphery of the respective rotary disk, wherein
each rotary disk exhibits
a peripheral recess forming a pull slot formed along a part of the periphery of the respective rotary disk, during rotation of the power unit, arranged to expose the pull magnets on opposing rotary disks while passing along the push slot,
a second recess forming an arc shaped push slot, formed along a part of the respective rotary disk on diametrally opposite side of the push slot, and arranged at a radially displaced position in a direction toward the drive shaft, for during rotation of the power unit to expose the push magnets on opposed rotary disks, wherein
the first rotary disk and the second rotary disk are mutually inclined along the longitudinal axis of the drive shaft, having a first point on the periphery where a magnet pair is located adjacent to each other, and with a second point on diametral opposite side of the drive shaft, where another magnet pair is arranged at a mutual distance, and wherein
the second power unit is turned about 90 degrees around the drive shaft in relation to the first power unit.
Each rotary disk exhibits a bearing housing, accommodating a bearing, arranged to rotate about the drive shaft through a hub fixedly connected to the stator plate. Moreover, each rotary disk exhibits a center hole provided with teeth, in engagement with wedge seats in the drive shaft, and exhibiting at least 6 magnet pairs.
Adjacent rotary disks are mutually inclined by an angle in the range from about 3 to about 10 degrees, particularly about 5 degrees.
Each stator plate is advantageously provided with a grip to enable the stator plate to be turned about a trace in the hub and lock it in a desired position.
The rotary disks are advantageously secured by snap rings, so that the bearing is not pulled out of and released from the hub.
The invention is in the following described in further details by means of drawings, where

In the illustration in
The second rotary disk 102 is formed symmetrically with the first rotary disk 101, but in a mutual inclined configuration described further below. The respective rotary disk 101, 102 each exhibits a bearing housing 103, accommodating a bearing 104, arranged to rotate about the drive shaft 200 through a hub 205, fixedly connected to the stator plate 203. The hub 205 is provided with a bore 206 through which the drive shaft 200 is extending. The bore 206 in the hub 205 has a diameter larger than the diameter of the drive shaft 200, so that the drive shaft 200 can rotate freely, independent from the hub 205 and the accompanying stator plate 203. The hub 205 and the accompanying fixed stator plate 203 are supported by the frame 201 through support means 204. However, the stator plate 203, which in part serves as shielding between magnets on adjacent rotary disks 101 and 102, can be rotated about the hub 205 and locked in a desired position by means of a lockable recess 214 in the hub 205. This is illustrated in
The rotary disks are advantageously secured by snap rings, to prevent the bearing 104 from being pulled out and away from the hub 205.
The first and second rotary disc 101 and 102 in a rotary disk pair in a power unit 100 are arranged at a mutual angle. A shown in
Now with particular reference to
In a similar manner, a peripheral recess 213 is formed, which in the following also is denoted as push track 213. The radial extension of the push track 213 is sufficient to expose the pull magnets 300− of the adjacent rotary discs 101 and 102, but not more than that the push magnets 300+ of the adjacent rotary discs 101 and 102 are shielded with respect to each other. The arc length of the pull track 212 is selected as needed, but not longer than half of the length of the circular arc minus the extension of the magnets 300− and 300+ within a magnet pair 300. As is apparent from
Moreover,
The position of the push magnet 300− and the pull magnet 300+ in a magnet pair of a rotary disc is illustrated by dotted lines.
