Description

A SYSTEM FOR REGENERATING INTERNAL ENERGY

FIELD OF THE INVENTION

The present invention is related, generally to a system a system for regenerating internal energy and more particularly, but not exclusively to a system of invention relates to a system for regenerating energy which comprises battery, brushless direct current motor, permanent magnet generator.

BACKGROUND

The multitude of electrical and electronic devices in common use today, from cellular telephones to computers to lighting systems, all depend on a steady supply of electrical energy. Such a supply is not an issue when a device is connected to a constant source of electrical energy via a land electrical power line, for example through a power receptacle. However, portable electrical devices or devices located in areas without electrical power lines (for example marine craft, space vehicles, non-powered air vehicles, etc.), must acquire their electrical energy from batteries or through other electrical energy sources (solar panels, hydro-power generators, fuel cells, wind-power generators, etc.). Examples of portable electrical devices include, but are not limited to: miniature electrical devices (such as: an implantable cardiac device (pacemaker, defibrillator), a chronograph, a miniature surveillance device (remote mini-camera, concealable tracking device, motion detecting device), an electronic tag (RF, etc.), and small to medium electrical devices (such as a personal electronic device (a mobile telephone, a radio, a television, a personal digital assistant (PDA), a media player and/or recorder, a video or photo camera, a game console, binoculars, night vision goggles, a portable computer (notebook, laptop, or tablet computer), a portable data acquisition device (i.e. RF or barcode scanner), a portable medical diagnostic or treatment delivery device (e.g. blood pressure monitor, electrocardiogram machine, defibrillator, drug pump, etc.), a surveillance device (remote camera, tracking device, motion detecting device), a weapon or weapon accessory with electrical or electronic capabilities (e.g., a camera and/or scope on a rifle, a taser, a laser targeting sight, or a laser targeter), toys, and robotic devices. In order to overcome the challenges faced by the people to achieve the constant supply of electrical energy for electronics and electrical devices, a plurality of energy regeneration techniques have been explored and experimented by researchers and engineers. Such conventional techniques include but limited to generation of electrical energy in an internal reforming high temperature fuel cell, self-generating device provided with an internal heat dissipation mechanism, using internally generated field to achieve poling during cycling etc. However, such solutions lack provisions of accommodating regeneration of electrical energy without using external resources and energy. Hence, there is a need for a system for regenerating internal energy independent of any kind of external resources and energy.

In the following detailed description of the embodiments of the disclosure, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the disclosure may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may be utilized and that changes may be made without departing from the scope of the present disclosure. The following description is, therefore, not to be taken in a limiting sense.

Figure 1 illustrates an exemplary architecture of a system for regenerating internal energy, in accordance with some embodiments of the present disclosure.

As shown in Figure 1, the exemplary system (100) comprises one or more components configured for regenerating internal energy and storing the regenerated energy in the battery for further use. The exemplary system (100) comprises a shaft (102), a pair of flywheel (104-1, 104-2, hereinafter combinedly referred to as 104), a brushless direct current (BLDC) motor (106), a pair of permanent magnet generator (PMG) (108, 110), a PMG output (112), a BLDC controller (114), a battery (116), a running controller (118), a battery charging controller (120), a set of bearings (122), and a fitting fabricator (124).

The shaft (102), popularly known as rotor shaft, is a central component of the electric motor. The rotor shaft is the carrier shaft for the laminated core of the rotor and thus transmits the electrically induced torque via a corresponding positive connection in the transmission. Further, the shaft (102) is a cylindrical component that extrudes out from a motor and housing of the motor. The purpose of the shaft (102) is to convert energy from the motor into the end use application. The shaft (102) can carry gears, pulleys and sprockets to transmit rotary motion and power via mating gears, belts and chains. In one embodiment, the material used for shaft (102) is mild steel. When high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used to manufacture the shaft (102). The shaft (102) is generally formed by hot rolling and finished to size by cold drawing or turning and grinding.

In one embodiment, the pair of flywheels (104) are attached to opposite ends of the shaft (102). The flywheels are used for storage of kinetic energy. The momentum of the flywheel causes it to not change its rotational speed easily. Thus, the flywheels help to keep the shaft (102) rotating at the same speed. Such configuration helps when the torque applied to the shaft (102) changes often.

The BLDC motor (106) is a synchronous motor using a direct current (DC) electric power supply. The BLDC motor (106) uses the BLDC controller (114) to switch DC currents to the motor windings producing magnetic fields which effectively rotate in space and which the permanent magnet generators follow. The BLDC controller adjusts the phase and amplitude of the DC current pulses to control the speed and torque of the BLDC motor (106).

The BLDC motor (106) comprises stator, sleeve, isolator, permanent magnet, and rotor core, wherein the rotor is the permanent magnet. In the BLDC motor (106), coils do not rotate, but are instead fixed in place on the stator. Because the coils do not move, there is no need for brushes and a commutator.

In the BLDC motor, the permanent magnet that rotates, wherein such rotation is achieved by changing the direction of the magnetic fields generated by the surrounding stationary coils. To control the rotation, the adjustment of the magnitude and direction of the current into these coils are required.

The advantages of a brushless motor over brushed motors are high power-to-weight ratio, high speed, nearly instantaneous control of speed (rpm) and torque, high efficiency, and low maintenance. Brushless motors find applications in such places as computer peripherals (disk drives, printers), hand-held power tools, and vehicles ranging from model aircraft to automobiles. In modem washing machines, brushless DC motors have allowed replacement of rubber belts and gearboxes by a direct-drive design.

The permanent magnet generator (108, 110) is a generator where the excitation field is provided by a permanent magnet instead of a coil. The rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft mounted permanent magnet mechanism and current is induced into the stationary armature. The PMGs (108, 110) are the majority source of commercial electrical energy. The PMGs (108, 110) are commonly used to convert the mechanical power output of steam turbines, gas turbines, reciprocating engines and hydro turbines into electrical power for the grid. Some designs of Wind turbines also use this generator type.

For some applications, the magnetic field of the PMG (108, 110) may be provided by permanent magnets. The rotor structure can consist of a ring of magnetic iron with magnets mounted on its surface. A magnet material such as neodymium -boron-iron or samarium-cobalt can provide a magnetic flux density in the air gap comparable to that produced with field windings, using a radial depth of magnet of less than 10 millimetres. Other magnet materials such as ferrite can be used, but with a considerable reduction in air-gap flux density and a corresponding increase in generator dimensions.

Permanent-magnet generators are simple in that they require no system for the provision of field current. They are highly reliable. They do not, however, contain any means for controlling the output voltage. A typical example of use is with a wind turbine where the generator output of variable voltage and frequency is supplied to a power system through an electronic frequency converter.

In one embodiment, the pair of PMG (108, 110) without carbon is communicably attached with the BLDC motor (106) over the shaft, wherein each of the BLDC motor (106) and the pair of PMG (108, 110) are installed over the shaft (102) by means a set of bearings on the shaft (102) so as to transmit the rotational energy efficiently. Further, the PMG output is also installed over the shaft (102).

In another embodiment, the output of the pair of PMG (108, 110) is transmitted to the battery charging controller (120) so as to further control the generated electrical energy.

While the BLDC motor (106) is mechanically relatively simple, the BLDC motor (106) requires sophisticated control electronics and regulated power supplies. The BLDC controller serves the purpose of controlling the BLDC motor (106). The BLDC controller regulates the speed and torque of the BLDC motor (106) and the BLDC controller can also start, stop, and reverse rotation of the BLDC motor (106). The BLDC controller detects the position of the rotor either by using sensors (for example, a Hall-effect sensor) or without using sensors. The sensors measure the rotor’s position and send out the data. The BLDC controller receives the information and enables the transistors to switch the current and energize the required winding of the stator at the right time. The BLDC controller can be one of proportional integral (PI) controller and proportional integral derivative (PID) controller.

A PI controller is a type of controller formed by combining proportional and integral control action. In the PI controller, the control action of both proportional, as well as the integral controller, is utilized. This combination of two different controllers produces a more efficient controller which eliminates the disadvantages associated with each one of them.

A PID controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. The PID controller continuously calculates an error value as the difference between a desired setpoint (SP) and a measured process variable (PV) and applies a correction based on proportional, integral, and derivative terms (denoted P, I, and D respectively).

In one embodiment, the battery can be 12V or 24V or some higher voltage. The battery can further be of 7A to 120A or having some more electric carrying capacity. There are four terminals in the battery in which two are (-) and two are (+). One is (-) and one is (+) in above. The battery is connected to the BLDC motor (106) for supplying electrical energy to the BLDC motor (106). The BLDC motor (106) gives electricity on R.P.M. 10 to 16000.

The battery charging controller (120) limits the rate at which electric current is added to or drawn from the electric batteries to protect against electrical overload, overcharging, and may protect against overvoltage. Such regulations prevents conditions that reduce battery performance or lifespan and may pose a safety risk. The battery charging controller may also prevent completely draining ("deep discharging") a battery, or perform controlled discharges, depending on the battery technology, to protect battery life. The battery charging controller may refer to either a stand-alone device, or to control circuitry integrated within a battery pack, battery-powered device, or battery charger.
