Abstract:In an Electrical machine, the Armature Reaction produces a Counter-Electromagnetic-Torque during on-load and off-load conditions.An effect of Armature Reaction reducesthe generated EMF due to decrease in value of flux per pole.In order to reduce the effect of armature reaction in the machines and thereby to improve the efficiency of the electrical machine in electromechanical energy conversion a new concept is proposed in this project. The regenerative acceleration generator coil takes advantage of the structure of a high impedance, multiple-loop salient pole winding or low impedance bi-filar windings to create a positive armature (accelerative) reaction rather than a negative (decelerative) reaction as exhibited by prior art generators which only have low impedance multiple loops of wire making up their rotor armature. The generator reverses these negative effects by delaying current flow in the coil until the rotating magnetic field reaches top dead centre. The new Generator technology use induced magnetic fields to accelerate the system on-load and produce a Complementary Electromagnetic-Torque, rather than decelerating it via the Counter-Electromagnetic-Torque. This technique would be implemented in Electric vehicles.

INTRODUCTION
Generator Armature Reaction’s Counter-Electromagnetic-Induced-Torque works in opposition and reduces the drive shaft torque supplied by the prime mover. Generator Armature Reaction produces system deceleration and the greater the magnitude of Load Current delivered by the generator to the load, the greater the magnitude of the Induced Magnetic Field produced around the current bearing wires which make up the generator coils. The greater the magnitude of generator Load Current, the greater the magnitude of Counter-Electromagnetic-Torque produced (and system deceleration) — the more the input power to the prime mover must be increased in order to overcome the generator’s Counter-Electromagnetic-Torque.
LITERATURE REVIEW
Thane Christopher hiens, a Canadian physicist invented this topologyalso developed the theory of ReGenXgenerator[1]. The ReGenX Generator allows electric vehicle generators to recharge the EV’s batteries while simultaneously accelerating the EV and to recharge the EV’s batteries while simultaneously decelerating the EV below a certain speed.The greater the magnitude of battery recharging in EV Regenerative Acceleration Mode the faster the rate of battery recharging and the fasterthe rate of EV acceleration. The greater the magnitude of battery recharging in EV regenerative braking mode the faster the rate of batteryrecharging and the faster the rate of EV deceleration. The magnitude of battery recharging current supplied by the ReGenX Generator in EVRegenerative Acceleration Mode is limited only by the physical size of the ReGenX Motor used.
PROPOSED SYSTEM
The ReGenX Generator technology use induced magnetic fields to accelerate the system on-load and produce a Complementary Electromagnetic-Torque, rather than decelerating it via the Counter-Electromagnetic-Torque. The ReGenX Generator is proven to reverse Generator Armature Reaction by introducing a Load Current Delay into the generator’s performance. The ReGenX Generator is designed to reverse Generator Armature Reaction by introducing a Load. The proposed system is shown in figure 1.

CONVENTIONAL COILGENERATOR
When a rotor magnet approaches a conventional generator coil the current direction produced in the coil creates a magnetic field around the coil.It is shown in fig 3.The magnetic field polarity of the coil’s induced magnetic field is always the same as the approaching rotor magnet’s polarity. Because like magnetic field polarities repel each other, the coil’s induced magnetic field performs work when it reduces the kinetic energy of the approaching rotor magnet.
REGENX COIL GENERATOR
The ReGenX Generator technology use induced magnetic fields to accelerate the system on-load and produce a Complementary Electromagnetic-Torque, rather than decelerating it via the Counter-Electromagnetic-Torque. The ReGenX Generator is proven to reverse Generator Armature Reaction by introducing a Load Current Delay into the generator’s performance.It is shown in fig 5.
An induced EMF (voltage) will cause a current to flow in a closed circuit in such a direction that its magnetic effect will produce a Complementary-Electromagnetic-Torque which will assist the change that produces it.
Regenx coil follows the principles such that
1. In a ReGenX coil, an induced voltage will cause a delayed current to flow through a load in such a direction that its delayed net magnetic effect will produce a Complementary-Electromagnetic-Torque that will assist the change that produces it.
2. The delayed net magnetic effect produced by the ReGenX coil’s delayed net load current is always in a direction to assist the turning action of the prime mover.
3. The ReGenX coil’s>45 degree load current delay — delays in the time domain; the net induced magnetic effect in a salient pole generator coil configuration such that the load current sine wave crest (load current and induced magnetic field peak magnitude) occur after the rotating magnetic field pole has already passed the coil’s core at top dead centre.
4. This load current delay and the subsequent the delayed induced magnetic effect accelerates the rotor pole magnet’s departure away from the coil while also simultaneously accelerating the opposite rotor magnetic pole which is approaching the coil.
5. In the case of the ReGenX coil’s operation, an induced current is caused to flow through a load and for power to be dissipated through that load but it does not require the expenditure of additional input energy.
6. The ReGenX coil always requires a prime mover input power reduction when the ReGenX coil is placed on-load and when power is dissipated through the load.
BIFILAR COIL
Bifilar Coil contains two closely spaced, parallel windings. In engineering, the word bifilar describes wire which is made of two filaments or strands.
CONCLUSION
The nature of the ReGenX coil design and operationis such that the ReGenX coil is caused to perform as both a capacitor and an inductor.The combination of these two operations is adequate to produce a sufficiently long enough Load Current Delay.It has advantages of capable of reversing Generator Armature Reaction / Generator on load Counter Electromagnetic Torque /Generator Complementary Electromagnetic Torque in its place
In an electric vehicle; Generator Armature Reaction’s Counter Electromagnetic Torque performs work reducing the kinetic energy of the EV — decelerating it when recharge current flows in the generator coils and is delivered to the EV’s batteries. All torque is work and all work requires energy — the energy required to produce the Counter Electromagnetic Torque is provided by the magnetic fields which are created around the generator’s current bearing wires.Such a ReGenX coil generator setup with its increased efficiency and reduced armature reaction could be installed in the Electrical Vehicles.
Under open circuit condition
If a load of infinite resistance (open circuit) is placed on the generator’s output terminals, the load current will be zero and no Generator Armature Reaction will be produced inside the generator because no magnetic fields are created and the input power requirement to the prime mover will be minimal.
Under short circuit condition
If a load of zero resistance (short circuit) is placed on the generator’s output terminals, the load current will be maximum and maximum Generator Armature Reaction is produced around the generator coils current bearing wires inside the generator because the magnetic fields are created are at a maximum magnitude and they perform maximum work decelerating the prime mover.
The input power to the prime mover will also need be maximum or the work performed by the generator coil’s magnetic fields will completely stall the system.
VII. SCOPE FOR FUTURE WORK
Case (i)
Using high impedance coil with high DC resistance and high gauge wire .Because the DC resistance of the coil was so high it could not deliver any usable electric output –just system acceleration (Generator Armature Reaction reversal) when loaded.
Case (ii)
In parallel winding configuration could produce Regenerative Acceleration and usable electric power.
