Project Title

Design and simulation of an in wheel permanent magnet synchronous motor for an electric vehicle on finite element modeling software tool Ansys Maxwell

Project Area of Specialization

Electrical/Electronic Engineering

Project Summary

In this FYP the group will be designing and simulating the performance of a PMSM for an electric vehicle, on the software “ANSYS Maxwell” & they will learn about electric machine design in this fyp.

Project Objectives

1. Complete motor design & its simulation results presented in the form of an elaborate & comprehensive report, which will be shared with the upcoming EV industry in Pakistan as well as abroad, to secure any joint collaboration between DSU & the EV/HEV industry.
2. Conference / journal paper
3. A fabricated motor usind design & simulations obtained 

Project Implementation Method

For designing & simulation of PMSM we would be using finite element modelling tools Ansys Maxwell. to begin with analytical model would be made on RMXpt considering motor specifications. then it would be exported to maxwell 2d/3d for finite element analysis for flux weakening,mesh refinment,calculate losses & magnet working points. then a thermal model would be made to fing hotspots for cooling.

using these designs & simulations a motor would be fabricated to verfiy results 

Benefits of the Project

This fyp would contribute to global EV industry where a new technology on in weel PMSM are trending for various electric cars & other electric vehicles. This would also contribute to establish pakistan EV manufacturing sector by developing a working prototype motor to be used in EV specially electrica bikes which we foresee would be comming sooneer then expected. 

some benefits for this fyp are stated as follows:

Drive Longer

In-wheel motors remove efficiency losses associated with gear, differential and CV joints situated around the vehicle. Total vehicle weight is also reduced.

This means:

Greater range

Reduced running costs

Lower charge frequency

Better Handling

Individual wheel motors provide torque distribution to different wheels (torque vectoring)

This means:

Improved driver handling

Enhanced stability and control

Improved traction control

Shorter stopping distances

Creative Freedom

In-wheel motors revolutionize car design. No requirement for existing driveline Components

Means vehicle design can unlock opportunities for new services and revenue

Production Efficiency

In-wheel motors with integrated inverters do not require a gear, differential, drive-shafts or external drive electronics.

This means:

Comparable system cost

Reduced development cost

Lower manufacturing cost

More opportunity for modularity

Steering capability

The 360-degree steering capability is made possible by a rotating interface that sits above the corner of main arm. The top of the rotating interface is fixed to the vehicle and the lower interface is fixed to the arm.

Technical Details of Final Deliverable
