Description

FIELD OF THE INVENTION

The present invention relates to the field of energy conversion from mechanical/motional energy into electrical energy. More particularly, the present invention provides an improved alternator device for converting mechanical/motional energy into electrical energy.

BACKGROUND OF THE INVENTION

In this technologically running world, energy is essential for each and every system or machine to work. Energy can be of any type, for example heat energy, electrical energy, mechanical energy, chemical energy, and the like.

As we all know, energy can neither be created nor be destroyed, it can be converted from one form to another form. So, the energy conversion field has always been the subject of invention. The invention in energy conversion field takes place very frequently, at the same time it has never been easy to invent any device or method for converting one form of energy to another form of energy. It is already known through the study of thermodynamics that energy can be converted from one form to another form. For example, chemical energy into heat energy, heat energy into mechanical energy, mechanical energy into electrical energy, and the like.

Energy is the main requirement for the efficient working of the present industrial world. Moreover, the electrical energy is the main source of providing power to every industrial activity. The well-known methods for generating the electrical energy require the use of hydrocarbons which are polluting our environment. Hence, there is always a need for generating electrical energy from other energy sources.

Some of the well-known methods are use of hydro energy, wind energy, atomic energy, and other renewable energy sources into electrical energy. However, such conversion is not always hundred percent efficient and there is always a loss of energy during the conversion process.

Hence, there is always a requirement of devices which can efficiently convert naturally available renewable energy into electrical energy. Moreover, there is always a requirement of devices which can covert one form of energy into another form of energy without wasting the valuable part of the energy during the conversion process.

A lot of devices and methods have been suggested in the art for conversion of energy from one form to another form. The most wanted devices and methods in the field of energy conversion is a device which can convert mechanical energy into electrical energy. We have lot of sources around us which can give input as mechanical energy. However, due to lack of efficient devices and methods such mechanical energy input cannot be converted efficiently into another useful form of energy.

This problem of efficient conversion of mechanical energy into electrical energy is solved upto some extent. There have been some solutions to this problem, for example, electrical generator, hydraulic turbine and the like. Every such device and method has their own advantages and disadvantages and thus accordingly gets implemented.

Traditional solutions do provide a way for conversion of mechanical energy into electrical energy, but still have limitations. These limitations are based on sources of mechanical energy, loss of energy during conversion, compactness, installation and the like. A disadvantage of traditional alternators is the energy loss due to the contact between the magnetized disks and/or coil ducts. Another disadvantage of traditional alternators is the loss of energy due to the dual pole magnetization (North and South) of a same magnetized disk/coil duct during operation. Also, traditional alternators have N/S alternating members which results in magnetizing the fixed magnet, so it is difficult to turn the alternator. These traditional alternators require electromagnetic energy to enable them to rotate.

SUMMARY OF THE INVENTION

Accordingly, there is a need to develop a device adapted to convert mechanical energy into electrical energy which overcomes the abovementioned drawbacks.

A alternator device and a method for converting mechanical energy into electrical energy are disclosed by the present invention. The present alternator device works on the principle of magnetization.

According to an embodiment of the invention, the device is adapted to create a magnetic field with minimum amount of energy required to rotate the rotating disks without need of electromagnetic energy and operate the device for the production of electrical energy from mechanical energy.

The central opening (101&201) in each of the rotating disks (100&200) is adapted to receive the non-magnetic shaft (10) in such a manner to enable the rotating disks (100&200) to be mounted along the non-magnetic shaft (10).

According to an embodiment of the invention, the first rotating disk (100) comprises a circular body portion (102) having the central opening (101) centered about the disk axis of rotation and further comprises a plurality of first extension members (103) extending radially outwardly from the circumference of the body portion (102) away from the disk axis of rotation along a same planar plan. In an embodiment of the invention, the body portion (102) and the first extension members (103) are molded together and form a single piece as an integral part of the first rotating disk (100). Preferably, the first extension members (103) are spaced at an equal interval along the circumference of the body portion (102). The spaces defined between the first extension members (103) form the first coil ducts (104) of the first rotating disk (100).

According to an embodiment of the invention, the second rotating disk (200) comprises a circular body portion (202) having the central opening (201) centered about the disk axis of rotation and further comprises a plurality of second extension members (203) extending radially outwardly from the circumference of the body portion (202) away from the disk axis of rotation along a same planar plan. In an embodiment of the invention, the body portion (202) and the second extension members (203) are molded together and form a single piece as an integral part of the second rotating disk (200). Preferably, the second extension members (203) are spaced at an equal interval along the circumference of the body portion (202). The spaces defined between the second extension members (203) form the second coil ducts (204) of the first rotating disk (200).

According to an embodiment of the invention, the mounting members comprise a first hollow cylindrical ring (105) adapted to be coupled to the rotating shaft (10) and to the first rotating disk (100) for securely mounting the first rotating disk (100) on the rotating shaft (10). The central opening of the first metallic disk (100) is adapted to receive the first hollow cylindrical ring (105). The first hollow cylindrical ring (105) is adapted to be rotatable by the effect of the rotation of the rotating shaft (10). Accordingly, the first hollow cylindrical ring (105) enables the rotation of the first rotating disk (100) along with the the rotation of the rotating shaft (10).

According to an embodiment of the invention, the mounting members comprise a second hollow cylindrical ring (205) adapted to be coupled to the rotating shaft (10) and the second rotating disk (200) for securely mounting the first rotating disk (200) on the rotating shaft (10). The central opening of the second metallic disk (100) is adapted to receive the second hollow cylindrical ring (205). The second hollow cylindrical ring (205) is adapted to be rotatable by the effect of the rotation of the rotating shaft (10). Accordingly, the second hollow cylindrical ring (205) enables the rotation of the second rotating disk (200) along with the the rotation of the rotating shaft (10).

According to an embodiment of the invention, the first and second hollow cylindrical rings (105&205) are preferably made of a non-conducting material. The non-conducting material is preferably selected from a wood material, a plastic material, or a ceramic material. More preferably, the non-conducting material is plastic.

According to an embodiment of the invention, the coil base (310) has a circular perimeter (circumference) and coupled to the magnet (300) in such a manner to extend radially outwardly from the perimeter of the magnet (300) away from the centre axis of the magnet (300). As explained above, the magnet (300) can also be positioned on the planar surface of the central portion of the coil base (310).

According to an embodiment of the invention, the magnet (300) has a body portion preferably having a circular shape and a central opening (301) adapted to allow the passage of the rotating shaft (10). Preferably, the magnet (300) has a planar surface smaller in size than the planar surface of the first and second rotating disks (100&200). The planar surface of the magnet (300) is preferably similar in size to the surface of the body portions of the rotating disks (100&200). The magnet (300) is adapted to be mounted intermediate the first rotating disk (100) and the second rotating disk (200) along the rotating shaft (10). The body portion of the magnet (300) comprises a north side face (306) and a south side face (307). The north side face (306) of the magnet (300) projects towards one rotating disk (100 or 200) and the south side face (307) of the disk shaped magnet (300) projects towards the other rotating disk (100 or 200).

According to an embodiment of the invention, the mounting members comprises a rolling member (320) adapted to be coupled to the rotating shaft (10) and to the first and second rotating disks (100&200). The rolling member (320) comprises an opening adapted to receive the rotating shaft (10) for enabling the rolling member (320) to be mounted on the rotating shaft (10). The central opening (301) of the magnet (300) has suitable dimensions in order to receive the rolling member (320) without however being in physical contact therewith in order to avoid any movement of the magnet when the rotating shaft (10) and the rolling member (320) are in rotation. This is since the rolling member (320) is adapted to rotate with the rotation of the rotating shaft (10). In another embodiment of the invention, the mounting members further comprise rolling balls adapted to be coupled to the rolling member (320) and to the magnet (300) for securely holding the magnet (300) to the rolling member (320) and to the shaft (10) where the bearing balls are adapted to mounted between the rolling member (320) and the magnet (300) and adapted to avoid the rotation of the magnet (300) while the rolling member (320) is in rotation. The rolling member (320) is adapted to be mechanically coupled to the first and second rotating disks (100&200) using fixing members such as screws. The coupling between the rolling member (320) and the first and second rotating disks (100&200) allow these rotating disks (100&200) to rotate while the rotating shaft (10) and the rolling member (320) are in rotation.

The magnet (300) is adapted to remain immovable and static during the operation of the device (1). The rotating disks (100&200) and the magnet (300) are adapted to have suitable dimensions, including diameter and thickness, depending on the application to which the device is applied. In fact, increasing the dimensions (including thickness and diameter) of these components (100, 200&300) increases the overall power of the device and the amount of energy which can be generated by the device. These dimensions can vary from one application to another depending on the needs of each application and the amount of power desired.

According to an embodiment of the invention, the rotating shaft (10) is adapted to be rotated by a mechanical/motional force. The rotating shaft (10) being coupled to the rolling member (320), the rotation of the rotating shaft (10) triggers the rotation of the rolling member (320) which in turn is coupled to the first and second rotating disks (100&200) triggering their rotation. The magnet (300) remains static in position during the rotation of the rotation shaft (10) and the rotating disks (100&200). The magnet (300) produces a first magnetic field in the first rotating disk (100) and a second magnetic field in the second rotating disk (200). The first and second magnetic fields are of opposite poles. For example, the first magnetic field can be a North Pole and the second magnetic field can be a South Pole or vice versa.

The rotation of the rotating disks (100&200) allow the coil ducts (104&204) to pass through the coils (312A and 312B) enabling the generation of an electric filed which is transported by the wire winding which can be connected to electrical rectifiers. As shown in FIGS. 6A and 6B, a first group of the coils (312A) produces a first electrical flux (330) where a second group of the coils (312B) forms a second electrical flux (332) out of phase with respect to the first electrical flux. The first group of the coils (312A) producing the first electrical flux are connected to a first electrical rectifier (315A), where the second group of the coils producing the second electrical flux are connected to a second electrical rectifier (315B) with an inverter where the electrical charge is inverted to put the second electrical flux in phase with the first electrical flux such that both electrical fluxes are added to each other and do not cancel each other. FIG. 6A shows the first and second electrical currents (330 and 332) out of phase as produced by the coils (312A and 312B). FIG. 6B shows both fluxes in phase after inversion of the second electrical flux (332). The first and second electrical rectifiers (315A and 315B) are then connected to an electrical storage unit (such as a battery) for storing the electrical energy generated and/or to electrical components for power supply.
