Transportation plays an important role in all our day to day life. Advancements in technology have uplifted the transportation system into the next level by the introduction of E-Vehicle. E-vehicles are the replacement of gasoline vehicles which are the major reason for depletion of ozone layer. The main component of the E-vehicle is the motor which basically decides the efficiency of the vehicles. The design of the machine has a great impact on the efficiency and as well as on the engines output. Due to the poor analysis of electromagnetic properties of the motor, undesired fluctuations and pulsations would occur causing harmonics to take place thereby there is a huge increase in iron loss. This will also affect the control over the vehicle at low speed. A reasonable method to avoid such issues is to introduce an additional step of analyzing the electromagnetic properties before prototyping the machine. Analysis of the machine is done on the perspective with the integration of the motor and the other components. A new design phase where multi-domain analysis defines these phenomena will assist in the task of achieving an optimal design. A specific simulation tool for each domain is needed for analysis of the entire sys-tem. The co-simulation is carried out on a 10-pole, 12-slot interior Permanent Magnet Synchronous Motor (PMSM) in this paper to do finite element analysis in order to achieve the necessary efficiency.

The goal of the project is to build a portable, compact lawn mower system that uses solar energy to power the lawn mower engine. "Solar Powered Lawn Cutter with Water Sprinkler and Sweep" is a solar powered robot vehicle that can avoid obstacles and mow the lawn automatically. The 12V battery powers both the car’s propulsion engine and the lawnmower’s engine. Solar panels charge the battery, so no additional charging is required. The motors of the lawn mower and vehicle are connected to a microcontroller that controls all the motors. It also connects with an ultrasonic sensor that detects obstacles. If there are no obstacles, the microcontroller moves the car’s engine forward. When the ultrasonic sensor detects an obstacle, the microcontroller turns off the mower’s engine to prevent damage to objects/people/animals. If the direction does not change, the microcontroller turns the vehicle until it is away from the object and then pushes the lawnmower forward again. If the plant needs it, it will be watered according to the user’s actions.

In recent years, there is a growing interest towards Electric Vehicles (EVs) and Hybrid Electric Vehicles (HEVs) that have the highest possibility of lowering pollutants. The propulsion batteries of EVs are charged from the grid using an onboard charger. The chargers are a critical component of any electric vehicle, which requires high-efficiency charger with a high-power factor. This project proposes a battery charger consisting of a resonance circuit and step-up AC-DC converter that performs bridgeless single-power conversion. The input diode rectifier with conduction losses are reduced by using a bridgeless arrangement. By offering Zero Current Switching, the resonance circuit decreases the losses that occur across the diodes. Furthermore, inoculation of current due to the resonance circuit allows the transformer to excite the core in both directions, providing for high power capabilities. The efficiency of the charger and the quality of the power along with its harmonic are used to assess its performance. Furthermore, EV has inbuilt charger and so it must be tiny, light, and quick charging. In MATLAB/SIMULINK, the suggested converter is constructed and simulated. The suggested charger would use a method obtained through feedback linearization to adjust the correction in any power variations in a one-step power conversion.
