In-Wheel Motor Transmission System in Electric Vehicle
Abstract
Electric vehicle is the alternative, efficient and eco friendly in the future automobile industry. In today’s world due to depreciation of the fossil fuels rapidly, engineers have found the other mode of vehicle movement.ie- moving the car or a vehicle by the mode of electric motor. The end of the engines powered by fossil fuels and entering to the new era of electric automobile by 2075 almost 95% of the fossil fuel content and production from the earth will get over. There are electric vehicles like Tesla automobile and some other companies like Mahindra etc have started production of electric vehicles and the vehicle is powered by AC Induction motor, BLDC motor etc by using shafts and cv axle for transmission of power generated. Here this research paper is about the implementation of in-wheel electric motor, construction, mechanism and working of alternative design of 3 phase ac induction 4 pole motor with figures and tables.

Introduction
In 1887, AC Induction motor was invented by Nikola Tesla and Galileo Ferraris, known by Tesla motor. Ac induction motor is electrical device which works on the principle of electric magnetic induction, in which it consists mainly two parts stator and a rotor, and stator remains fixed and rotor rotates inside the stator, where both have the windings named stator winding and rotor winding . when ac current is supplied to the motor , magnetic field is produced which helps rotor to rotate in result rotates the shaft and wheel rotates .There are various types of ac induction motors like 2 phase induction motor, 3 phase induction motor. Tesla electric automobile which is the most efficient and fastest car in the world uses 3-phase 4 pole AC induction motor , whose wires are connected in star connection as shown in below fig.1.
Conclusion
This innovation will be proved very useful in the near future if this system will be installed in the electric cars and other vehicles and lots of problems will be solved by this. I am personally going to apply this on my experimental car which I am making can be seen in the fig. 7.
