The assignment focusses on defining a figure of merit for an inverter, and challenging the regular threephase two-level inverter specially with a multiphase inverter which is obtained by parallel connected discrete IGBTs.

The assignment can be subdivided in the following parts

  • Investigating how to model circuit path of each IGBT and different scenarios of sharing current
  • Modelling and simulating the inverter by using a circuit analysis software
  • Designing schematic and drawing a PCB for the circuit
  • Testing the circuit and deriving conclusions

Internship/Graduation Assignment: Fractional Slot Synchronous Reluctance Machine for Electric Powertrain

 

Internship/Graduation Assignment

Fractional Slot Synchronous Reluctance Machine for Electric Powertrain

 

About e-Traction
Founded in the Netherlands e-Traction offers superior technology in e-mobility and related services that is based on solid expertise and experience. Since 1981 the key focus has been to commercialize and integrate innovative and state of the art e-mobility solutions.

We developed a unique electric in-wheel powertrain technology which offers the essence of pure direct drive power. With our sustainable technology only a bare minimum of components is required to reach the highest efficiency level. The simplicity of our drivetrain is the ultimate sophistication.

Assignment description
e-Traction develops a unique electric in-wheel powertrain technology that offers the essence of pure direct drive power for heavy and light duty automotive applications such as city buses, urban distribution vehicles, airport modalities and SUV’s. These vehicles are propelled by TheWheel® , a direct-drive in-wheel motor system that integrates a permanent magnet synchronous motor (PMSM) with power electronics and fluid cooling into a wheel. e-Traction is constantly on the lookout for opportunities to make this product more robust, more efficient, and more powerful.

Nowadays PMSMs are the most commonly used motors for electric vehicles for their high torque densities. Nevertheless, synchronous reluctance machines (SynRMs) have attracted increasing attention from the automotive industry due to their robust structure and relatively low price. Most SynRMs discussed in literature are incorporating an integer-slot design with distributed windings, resulting in relatively large winding heads and hence a high end-winding loss and limited active length. This project is primarily aimed at a study on the feasibility of implementing concentrated windings into fractional-slot SynRMs, followed by the design of such a SynRM for a specific electric powertrain.

Deliverables
Report including:

  • State of the art of SynRMs
  • Feasibility study of fractional-slot SynRMs with concentrated windings
  • Design and optimization of a fractional-slot SynRM for a specific electric powertrain

Simulation models

Profile

  • Master level engineering, preferred Electrical Machines and/or Electronics
  • Prerequisites: Permanent Magnet Synchronous Machines (PMSM), Finite element analysis (FEA) modeling.

Duration

  • Option 1: three-month internship
  • Option 2: nine- to twelve-month graduation project

Internship Assignment

Improvement and extension of Hardware-In-the-Loop (HIL) testing

About e-Traction
Founded in the Netherlands e-Traction offers superior technology in e-mobility and related services that is based on solid expertise and experience. Since 1981 the key focus has been to commercialize and integrate innovative and state of the art e-mobility solutions.

We developed a unique electric in-wheel powertrain technology which offers the essence of pure direct drive power. With our sustainable technology only a bare minimum of components is required to reach the highest efficiency level. The simplicity of our drivetrain is the ultimate sophistication.

In addition to the inverter, which is located inside the in-wheel motor, e-Traction’s electronic control technology series consist of a sophisticated powertrain control module (PCM).

Assignment description
This assignment focusses on the validation of generated and hand-coded software of our in-house developed high voltage inverter and code generated PCM. Both ECUs are extensively tested before they are used on the road. The validation in this assignment will contribute to the improvement of the current tests and to extend these tests. As more functionality is added, test cases should be updated or added to increase the test coverage. Part of this assignment is also to determine the current test coverage and set a goal for the final coverage.

After software is unit tested and tested with Model-In-the-Loop (MIL) simulations tests the software is flashed to the target hardware (ECU) and it’s functionality is tested with this so called Hardware-In-theLoop HIL) tests. A real-time PC is simulating all vehicle behaviour in which both ECUs can be tested.

The assignee is expected to follow the processes defined at e-Traction. An out-of-the-box thinking as well as a pro-active approach to problem solving are encouraged.

The assignment consists of

  • Getting experience with Simulink Test, Continuous Integration (CI) and with the HIL hardware
  • Reading requirements and determine test scope of new test cases
  • Improving existing test cases and increase code coverage by adding new test cases
