MIKE BRADY’S “PERENDEV” MAGNET MOTOR<br />
ABSTRACT<br />
Patent Application WO 2006/045333 A1 4th May 2006 Inven<strong>to</strong>r Mike Brady<br />
PERMANENT MAGNET MACHINE<br />
The invention provides a magnetic repellent mo<strong>to</strong>r which comprises: a shaft (26) which can rotate around it's<br />
longitudinal axis, a first set (16) of magnets (14) arranged around the shaft (26) in a ro<strong>to</strong>r (10) for rotation with the<br />
shaft, and a second set (42) of magnets (40) arranged in a sta<strong>to</strong>r (32) surrounding the ro<strong>to</strong>r. The second set of<br />
magnets interacts with the first set of magnets, and the magnets of both sets are at least partially screened so as<br />
<strong>to</strong> concentrate their magnetic field strength in the direction of the gap between the ro<strong>to</strong>r (10) and the sta<strong>to</strong>r (32).<br />
BACKGROUND<br />
This invention relates <strong>to</strong> a magnetic repellent mo<strong>to</strong>r, or drive mechanism. Such a mechanism may be useful for<br />
driving an electrical genera<strong>to</strong>r, a vehicle, a ship, an aircraft, or the like.<br />
Conventional power sources rely on fossil fuels or secondary power sources such as nuclear power, or electricity<br />
derived by whatever means, for its source of driving power. All of these sources of power suffer from<br />
disadvantages such as being the cause of pollution, requiring transportation or transmission over long distances<br />
<strong>to</strong> the point of use, and being costly <strong>to</strong> purchase. Thus, there is a need for a power source which is substantially<br />
pollution-free in operation, requiring substantially no external power, and which is simple <strong>to</strong> maintain.<br />
SUMMARY<br />
This invention provides a magnetic repellent mo<strong>to</strong>r which comprises: a shaft which can rotate about its<br />
longitudinal axis, a first set of magnets which are arranged around the shaft and which rotate with the shaft, and a<br />
second set of magnets arranged in a sta<strong>to</strong>r surrounding the ro<strong>to</strong>r, where the second set of magnets reacts with<br />
the first set of magnets, both sets being partially screen magnetically in order <strong>to</strong> direct their magnetic field in<strong>to</strong> a<br />
gap between the two sets of magnets. Thus, the interaction of at least some of the magnets of the first and<br />
second sets urge the shaft <strong>to</strong> rotate.<br />
The interaction may be the net force of like magnetic poles repelling each other thereby urging the magnets away<br />
from each other, however, since only the ro<strong>to</strong>r magnets can be moved by this urging force, the shaft is urged <strong>to</strong><br />
rotate in<strong>to</strong> a position where the repelling force is less.<br />
The ro<strong>to</strong>r may be substantially disc-shaped and the first set of magnets may be located in a peripheral region of<br />
the ro<strong>to</strong>r which rotates with the shaft. The sta<strong>to</strong>r may be in the form of a pair of arms aligned with the ro<strong>to</strong>r.<br />
These sta<strong>to</strong>r arms can be moved relative <strong>to</strong> each other and away from the ro<strong>to</strong>r, in order <strong>to</strong> allow the gap between<br />
the ro<strong>to</strong>r and the sta<strong>to</strong>r <strong>to</strong> be set selectively. The gap may be set manually, for example, by a hand wheel, or<br />
au<strong>to</strong>matically, for example by a system of weights which move centrifugally and so form a rotational speed control<br />
which acts au<strong>to</strong>matically, i.e. the smaller the gap, the greater the repulsion forces between the magnets of the<br />
ro<strong>to</strong>r and sta<strong>to</strong>r.<br />
Both the ro<strong>to</strong>r and the sta<strong>to</strong>r may have more than one set of magnets. The magnets may be placed in sockets<br />
which extend <strong>to</strong>wards the circumference of the ro<strong>to</strong>r. These sockets may be substantially cylindrical and<br />
arranged in a plane which is perpendicular <strong>to</strong> the longitudinal axis of the ro<strong>to</strong>r shaft. These sockets may also be<br />
arranged at an acute angle relative <strong>to</strong> the tangent <strong>to</strong> the circumference of the ro<strong>to</strong>r disc where the mouth of the<br />
cylindrical socket is located. Similarly, the sta<strong>to</strong>r magnet sockets may be angled relative <strong>to</strong> the inner<br />
circumference of the sta<strong>to</strong>r. These angles may be between 18 degrees and 40 degrees, but preferably between<br />
30 degrees and 35 degrees.<br />
These sockets may have a socket lining consisting at least partially of a magnetic screening material. The socket<br />
lining may line the entire extent of the sockets so that only the opening <strong>to</strong> the exterior remains unlined. In another<br />
embodiment of the invention, the magnetic screen lining may cover a substantial percentage of the whole of the<br />
socket lining, e.g. 50% of the socket lining.<br />
The magnets may be Nd-Fe-B of dimensions which fit snugly inside the linings of the sockets. These magnets<br />
may be cylindrical in shape and have a 37 mm diameter, a 75 mm length and a magnetic strength of 360,000<br />
gauss. The socket lining, magnetic shield and magnet may all have a hole through them <strong>to</strong> receive a securing<br />
pin, preferably positioned so that it is parallel <strong>to</strong> the longitudinal axis of the shaft.<br />
