Abstract
This invention is related to electric machines - engines and generators. The operation principle of the proposed electric machine design is based on properties of moving conductor in a magnetic field (in generator mode) or on the properties of Ampere's force (in motor mode). On the basis of these properties, three related designs of reciprocal motor or generator are proposed: longitudinal, annular and arch-shaped. The proposed reciprocal electric power generator or motor contains pairs of permanent magnets. Each magnet pair is connected by the same magnetic pole to a ferromagnetic core thus producing the magnetic field of a desired specific shape and amplifying it by the factor of 'm'. Such connection of the magnets can be of longitudinal, annular or other shape. The windings mounted on the magnetic core should be able to move relatively to the magnetic core, or the core, relatively to the windings. The generator operates very efficiently (in generation mode) and produces substantial amounts of electric power, despite its relatively small dimensions and inexpensive design.
Description
This invention is related to electric
machines - motors and generators.
Traditional electric machines are based
on electromagnetic induction or interaction between
electric currents and magnetic fields. Any electric
machine containing permanent magnets can operate as an
electric power generator or an electric motor.
A similar invention is described in the
US patent No.US5347186 (A). The said generator
contains two magnets in the cylinders and the windings
that are mounted next to the magnets; the magnets change
the magnetic field when moving relatively to each
other and thus produce induction. Such generator could
be successfully deployed in the fields of signalling and automation.
Presently, the need to capture the
power of waves as an alternative or even the primary
energy source for mankind becomes ever more urgent
(important). The proposed electric power generator or
motor fits the requirements for conversion of wave
oscillations into electric energy. However, the field
of application is not limited to wave power generation.
The operation principle of the
proposed design of the electric machine is based
on conductor motion properties in a magnetic
field (when operating as a generator) or on the
properties of Ampère's force (when
operating as a motor), tough it also could be
explained on the basis of magnetic flux
alteration inside the windings. On the basis of
these properties, several related designs for
the motor or the generator are proposed:
longitudinal, annular or of an arbitrary shape.
The proposed new reciprocal
electric power generator or motor has one or
multiple pairs of magnets and ferromagnetic cores
between them. The magnets of each pair are connected
by the same poles to a ferromagnetic core, thus
producing magnetic field of specific shape and
amplifying it by the factor of 'm'.
The connection of the magnets can be
longitudinal, annular or of arbitrary shape. The
windings mounted on the magnetic core should be
able to move relatively to the magnetic core, or the
core, relatively to the windings. When electric
current flows though the windings (operation in
motor mode), interaction between the electric
current and the magnetic field creates
Ampère's force, the vector lines of which take
longitudinal or other shape, depending on the shape
of the core. When the winding and the core move
relatively to each other, the movement of conductor
in the magnetic field produces an electromotive
force (operation in generation mode). This type
of generator is characterized by high efficiency.
The reciprocal electric power
generator or motor may contain a magnetic screen
- magnetic circuit that not only protects
environment from magnetic fields, but also
significantly increases efficiency of electric
power generator or motor.
The appended drawings illustrate the following:
Fig. 1 - The shape of generator or
motor core and of magnetic field in longitudinal
generator or motor design.
Fig. 2 - Design of generator or motor
containing a core and a winding.
Fig. 3 - Design of generator or motor
containing multiple windings - multiple phases.
Fig. 4 - Generator or motor of annular design.
Fig. 5 - Generator or motor containing
a magnetic screen- a magnetic circuit.
Fig. 6 - Generator or motor of
arch-shaped design.
The proposed design of reciprocal
electric power generator or motor converts mechanical
movement into electric power or, vice versa, electric
power into mechanical movement. The principle of
operation is illustrated in Fig.1 and Fig.2. Fig. 1
demonstrates how magnets 1 and ferromagnetic core 2
form the magnetic field. Fig.2 illustrates the position
of winding in the magnetic field. When electric
current flows through the winding 4, it interacts with
the magnetic field created by the magnets 1 and the core 2.
Ampère 's force created by
interaction between the winding and the magnetic field
generates movement that depends on the shape of the core.
Fig. 3 presents a
multi-polar/multi-phase generator or motor. Fig 4.
presents annular version of the design. Fig.5. presents
the version containing a magnetic screen 5. The
magnetic screen 5 serves three purposes:
- Connection of magnetic fields of adjacent magnets and amplification thereof by the factor of 'm'. Thus the windings are traversed by the amplified magnetic field that cannot dissipate in the environment.
- Protection of environment from alternating magnetic fields created by moving magnets;
- Forcing the magnetic flux to traverse the windings at the right angle.
The reciprocal electric power
generator or motor operates even without the magnetic screen.
The motive force of the reciprocal
electric power generator or motor may be increased
without increasing consumption of electric power.
Since the Ampère's force (FA=I·L·B·sin
α) is directly proportional to the strength of
magnetic field, the length of the conductor and the
electric current, the motion force could be increased by
increasing the length of the conductor or the magnet
parameters (magnetization or dimensions), without
increasing the electric current.
Laboratory research demonstrated that
movements of the electric power generator or motor
(operation in motor mode) automatically stabilize,
since a conductor moving in a magnetic field generates
electric current of the same polarity as that of the
power supply voltage.
The operation of the reciprocal
electric power generator or motor as a power generator
is based on the properties of conductor movement in
permanent magnetic field.
Both mechanical and electronic
collectors-commutators can be used in the reciprocal
electric power generator or motor. When operating in
power generation mode, the collectors may be absent.
The number of windings is not specific and depends on
requirements. Therefore it does not constitute a basis
for another patent.
The proposed electric machine
(reciprocal electric generator or motor) is
characterized by:
- Substantial material economy, since the amount of ferrous metals in the device is significantly reduced (ferrous metals in rotors and stators of modern motors and generators make the major part of their mass);
- Electric energy is not used for remagnetization of magnetic circuits and magnetic core (motor mode) leading to economy of electric energy;
- The device is very quiet. All modern generators operate under varying load conditions leading to increased vibration and higher noise levels. The proposed device is free of this shortcoming.
- The electric machine operates well as generator in the range of relatively low speeds, which makes it very useful. This generator suits well for construction of wave power farms, where mechanical movements are slow. It is ideally suited for mounting on a ship, i.e., for power generation from wobbling movement of a ship, raft or another floating body.
