The present invention generally relates to torque generating devices and more particularly relates to a conducting liquid vortex DC motor.
Normally, electric motors are used as torque generators and are basically electric machines that converts electrical energy into mechanical energy. These electric motors are available with stator and rotor parts with conductive windings. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a conductor wire winding to generate force in the form of torque applied on the motor shaft. These conductors are placed in a magnetic field of the air gap and thus, each conductor experiences a reciprocating force. This air gaps may cause various losses and may end up with reduction in motor efficiency. The conductor lies near the surface of the rotor at a common radius from its center. Hence, the torque is produced around the circumference of the rotor, and the rotor starts rotating. This torque produced is transferred to the shaft of the rotor and drives the mechanical load. However, the electric motor has the deficiencies, winding wear down during stoppage due to eddy currents, winding losses, finite resolution, eddy current losses and like. Also, the electric motors demand high maintenance cost.
Accordingly, there exists need to provide a conducting liquid vortex DC motor as torque generator that is completely free from wire windings and can overcome the drawbacks of the prior art techniques.
Objects of the invention
An object of the present invention is to convert electric power in to mechanical power and transfer the mechanical power to an external load with minimum transmission losses.
Another object of the present invention is to provide an efficient fluid coupling that can transfer mechanical power with minimum transmission losses.
Yet another object of the present invention is to produce torque from fluid coupling by replacing stator and rotor windings of a conventional electric motor.
A conducting liquid vortex DC motor comprises, a terminal vessel having a pair of conducting terminals coupled to an electric power source, an electrically conducting liquid being occupied in the terminal vessel, a plurality of magnets placed in close contact with the terminal vessel, a blade plate being rotatably mounted above the terminal vessel, a coupling means mechanically couples the blade plate to an external load and a gasket installed between the top edge of the terminal vessel and an acrylic plate mounted above the terminal vessel. The electrically conducting liquid is placed between the pair of conducting terminals. The plurality of magnets include, a top magnet configured vertically above the terminal vessel, a bottom magnet configured vertically below the terminal vessel, and a plurality of side magnets configured laterally around the terminal vessel. The plurality of magnets are arranged in such a way that the magnetic field produced thereby covers the entire area of the conducting liquid and generates a uniform and stronger magnetic field therein. The blade plate having a plurality of grooves and blades configured thereon in close contact with the electrically conducting liquid. The blades are capable of absorbing any momentum produced in the conducting liquid, and the grooves allow vertical movements of the blade pale to compensate for the changing volume expansion of the conducting liquid due to temperature variations. The gasket fluidly seals the terminal vessel. When the conducting liquid is excited by an electric supply in the presence of a uniform and strong magnetic field therein, it experiences an angular momentum therein in a direction that is mutually perpendicular to both electric and magnetic fields around. Then the conducting liquid starts whirling inside the terminal vessel and transfers the momentum to the blade pate. The blade plate further couples this rotational force to the external load through the coupling means.

Referring to the figures from 1 to 8, a conducting liquid vortex DC motor (100) ("the motor (100)" hereinafter) is shown, in accordance with the present invention. The motor (100) comprises a plurality of magnets (10), an electrically conducting liquid (20), an electric power source (30) and a coupling means (40).
The terminal vessel (12) comprises an inner and an outer part that act as a first and a second DC terminal (12a, 12b) and are electrically coupled to the electric power source (30) for receiving electrical power therefrom. The inner part receives and occupies the electrically conducting liquid (20) ("conducting liquid (20)" hereinafter) therein and allows spinning of the conducting liquid (20) therein in a uniform angular velocity.
The first conducting terminal (12a) ("first terminal (12a)" hereinafter) is made up of Mild Steel with a coating of Nickel. This combination prevents any chemical reaction of the first terminal (12a) when comes in direct contact with the conducting liquid (20). The second conducting terminal (12b) ("second terminal (12b)" hereinafter) of the terminal vessel (12) is also made of Mild Steel with a coating of Ni so as to prevent any chemical reaction with the conducting liquid (20). Also, the second terminal (12b) is provided with a small curve that helps the conducting liquid (20) to rise upward due to centrifugal action which in turn helps the liquid (20) to rotate faster. Preferably the curvature radius is selected to be 60mm for better results. Preferably, the conducting liquid (20) is any one of the liquid selected from mercury, gallium, gallensteine or such alloys. In an alternative embodiment, the terminal vessel (12) is semispherical in shape.
The plurality of magnets include a top magnet (10a), a bottom magnet (10b) and a plurality of side magnets (1Oc). Preferably, the top and bottom magnets (10a,1Ob) are disc magnets and the plurality of side magnets (1Oc) are ring magnet. Preferably the plurality of magnets (10) are permanent magnets. In an alternative embodiment, the plurality of magnets (10) are made of ferromagnetic material preferably neodymium, to produce high magnetic flux density. The top magnet and bottom magnet are placed respectively on top and bottom part the terminal vessel (12). The side magnets are placed vertically, surrounding the terminal vessel (12) or perpendicular to the conducting liquid (20) in such a way that the magnetic field produced may cover the entire area of the conducting liquid (20) and generates a uniform and stronger magnetic field therein.
The conducting liquid (20) is placed between the first and second terminals (12a,12b) and between perpendicular magnetic fields produced by the plurality of magnets (10). In a specific embodiment, the least volume of conducting liquid (20) that must be sufficient for generating the required speed and torque is taken aslkg.
The terminal vessel (12) is fluidly sealed by a gasket (28) and oil film that prevents vapors of the conducting liquid (20) from escaping into the surroundings. The gasket (28) is installed between the top edge of the terminal vessel (12) and an acrylic plate (29). The acrylic plate (29) is provided on top side of the terminal vessel (12) as a lid for preventing the conducting liquid or its vapor from seepage or escaping in to the surroundings. This also gives a support structure for the top magnet (10a) that is placed on top side of the conducting liquid (20). Further, an acrylic base (32) is provided between the first and the second conducting terminals (12a,12b) to avoid any electrical short circuiting between the two terminals. This also allows the user, an easy inspection of the terminal vessel (12) without opening the sealed parts, as the acrylic material is transparent.
The terminal vessel (12) further comprises a blade plate (46) placed on top side thereof. The blade plate (46) having a plurality of blades and grooves at the bottom side thereon. The blade plate (46) is configured on the terminal vessel in such a way that the blades are in contact with the conducting liquid (20) and is capable of absorbing any momentum produced therein. The blade plate (46) is operably coupled to the coupling means (40) such that any movements experienced by the blade plate (46) from the conducting liquid (20) will be transferred to an external load there through.
The coupling means (40) comprises a vertical sleeve (42), a shaft (44), a dog clutch (43) and at least two bearings (48). The at least two bearings (48) include a first bearing seated between the first terminal (12a) and the shaft (44) and a second bearing seated between the shaft (44) and the top acrylic plate (32). The coupling means (40) interfaces the conducting liquid (20) movements and thereby transfers the torque produced therein to an external load. The vertical sleeve (42) is arranged to counteract the expansion and contraction of the conducting liquid (20) upon variable temperature conditions. The shaft (44) is mechanically coupled to a blade plate (46) that absorbs the rotational energy from the conducting liquid (20) in contact and transfer the torque produced by the conducting liquid to the shaft (44).
When a conducting liquid (20) heats up, it starts to expand and proportionally increases the overall volume. The bottom end of the shaft (44) contains a bearing seat to receive the at least two bearing (48) and the mid-section of the shaft (44) contains the vertical sleeve (42) and a dog clutch (43) to receive the external load. The top section of the blade plate (46) has groove thereon as that of the sleeve (42) such that the blade plate (46) can move vertically to compensate for the changing volume expansion of the conducting liquid (20) due to heating or cooling.
The at least two bearings (48) are capable of withstanding both axial as well as radial loads experienced by the shaft (44). In a specific embodiment, the least two bearings (48) are trapezoidal bearings that are used to handle both axial as well as radial forces. The radial loads are generated due to the rotation of the shaft (44) whereas the axial load is generated due to the external load attached to the shaft
(44).
The power source (30) is an external power source consisting an inductive coupling means and a rectifier (34). Preferably, the power source comprising a variable AC power supplies (VARIAC), a transformer (35) and metallic diode bridge rectifier. In an embodiment, the transformer (35) operates in step down configuration to reduce the voltage and consequently an increased current. In a specific embodiment, where the conducting liquid is mercury, the transformer (35) delivers 40A supply at its secondary terminals. The rectifier circuit employs metallic bridge rectifier diodes for rectification. The VARIAC is used to throttle the amount of voltage passing through the transformer hence limiting the current output at the secondary windings of the transformer (35).
Again, referring to the figures from 1 to 8, in an aspect of the invention, an operation of the motor is described in accordance with the present invention.
The conducting terminals (12a, 12b) receive electrical power from the power source (30) and delivers it to the conducting liquid (20). As the current flows through the terminals (12a,12b), together with the influence of the perpendicular magnetic field, the conducting liquid (20) starts accelerated in a direction that is mutually perpendicular to both electrical and magnetic fields around. This produces a rotational force based on the principle 'Lorentz force' force within the conducting liquid (20). The curved nature of the terminal vessel (12), that holds the conducting liquid (20) allows whirling of the conducting liquid (20) therein. The conducting liquid (20) further imparts the generated angular momentum to the blade plate (46) through the blades configured thereon. The blade plate (46) spins along with the conducting liquid (20) in a similar direction and this rotational motion is further coupled to the shaft (44). Thus, the rotational motion of the conducting liquid (20) is converted into shaft power by means of the coupling means (40) having the shaft (44) operably connected to the blade plate (46). The momentum thus generated is further coupled to the external load through the coupling means (40)
The blades in the blade palate (46) are designed in such a way that it can divert the conducting liquid (20) towards the center of rotation irrespective of the direction of motion, when the conducting liquid (20) tends to move towards the side of the terminal vessel (12) due to centrifugal force. This helps to circumscribe the conducting liquid (20) within the boundary of the terminal vessel (12) so as to avoid any chances of losing the contact with the first and second terminals (12a, 12b) and counteract the outward flow.
The torque produced by the conducting liquid (20) is based on magneto hydrodynamics, which is completely based on the principle of Lorentz forces. As name suggests, magneto-hydrodynamics deals with the dynamic motion of conducting liquid (20) in the presence of electric and magnetic field. When any electrically conducting liquid (20) placed in the presence of electrical and magnetic field, the liquid starts rotating due to simultaneous action of electrical and magnetic forces acing on it giving it acceleration and direction respectively. This happens due to the current induced in the conducting liquid (20) under the influence of the magnetic field, which in turn polarizes the conducting liquid (20) and reciprocally changes the magnetic field itself. Specifically, the conducting liquid (20) include plasma or liquid metals like mercury or gallium or gallensteine or such alloys.
The design specifications of an embodiment of motor (100) as follows; a) While designing the shaft (42), the axial and torsional load that may acting on the shaft has to be considered,

c) The amount of conducting liquid required to generate the required speed is determined by: V= nR2H The volume of the conducting liquid depends upon the outer diameter of the liquid, which can be found out as the internal diameter of the terminal vessel. The height of the conducting liquid is taken as 6mm to generate the optimum speed and torque. Hence

Where: h=6mm IT Do1 = outer diameter 1 of the first terminal OT Do2 = outer diameter 2 of the second terminal d) Referring to figure 8, the dimensions of the acrylic base (32),
ACl Di=IT D, 2 ACI Do= IT Do2 + 40mm
The value 40mm is chosen as to be the minimum difference between the inner and outer diameter of the acrylic base (32) as precautionary measure for the electric spark that may happened between the first and second terminals. ACl T =3mm Acrylic supporting bracket dimension, ACI TBR2 = ACl D, - ACl Di AC ISBR2 = IT SBR1
e) As the bearing is going to be seated on the top part of the first terminal, the design of first terminal (12a) by referring to figure 7 and figure 9: IT Doi= dl + 6mm, IT Dii = dl, IT Di2= d and IT Ll = T IT Do2= ((0.8(OT Do2 - IT Dol))-40)+ IT Dol IT TI = 3mm (overall) f) Supporting threaded bracket includes four brackets placed at 90° apart. Dimension as follows IT TBR1 = 0.2(IT Do2) IT SBR1 = 2(Dboltl) Heights of the IT as follows IT H total = IT L + M2 + 23mm + IT SBR1 IT h = 13mm + M2 +IT SBR1
g) Referring to figure 10, the dimensions of the second terminal (12b) include, OT Do2= as found out by the formula given above OT Dil =AC Do
OT R curvature = 60mm OT T = 3mm (overall) Small extruded plate for gasket dimension: OT Do3 = (3(Dbolt2))+ OT Do2+ 3 OT hl = 6mm second bracket dimension: OT SBR3 = IT SBR1 OT TBR3 = 0.2(OT Do2 - OT Dil) Height of the second terminal OT H = 12mm + OT SBR3 + OT h
h) The blade plate (46) is the element that rotates with the conducting liquid (20) and absorbs the energy there from. The blade plate (46) also performs the task of secondary terminals and also reduces vaporization of conducting liquid (20) as it floats over the liquid. The design of blade plate (46), with reference to figure 6b, is designed in such a way that it absorbs maximum energy from the conducting liquid (20) irrespective of its direction of rotation.
Design of the blade plate (46) as follows, BL Di= IT Do + 10mm BL Do= OT Di BL T plate = 3mm
Extruded blades from the plate design BL T blades = 5mm BL R des I = 60mm BL R des2= 140mm
i) Referring to figure 11, The gasket (28) design include: GS T = 3mm GS Di= OT Do2 GS Do= OT Do3 j) Referring to figure 8, the acrylic plate having dimensions:
AC2 Do= OT Do3 AC2 Di= d + 6mm AC T = 3mm AC D holes = D bolt2 (4 holes 900mmapart)
