Practical Exercise

On this page you will find information about the IEW internships

Here are the practical exercise offered by the IEW. After a short introduction text follows a link to Campus.

The contents of the practical course cover the main research areas of IEW: electrical machines and contactless energy transmission.

  • Coupled coils
  • Installation and commissioning of a power electronics for contactless energy transmission
  • Finite Element Simulation Magnetic Circuit
  • DC machine
  • Mains synchronization of an electrically excited synchronous machine
    asynchronous machine

Logon:

The registration is possible from 08.10.2018 at 08:00 o'clock, it ends on Wednesday, 17.10.2018 at 23:59 o'clock.
Students must register for the C@MPUS course 371200310 "Electrical Energy Conversion I" on the waiting list during this period.
In addition, the registration form must be completed and sent by e-mail to fachpraktikum@iew.uni-stuttgart.de
The number of participants is limited to 20 students, the time of registration in C@MPUS and the individual previous knowledge decide about a place in the internship. Enrolments and cancellations will be announced by e-mail from Friday, 19.10.2018 and the admitted students will be assigned to the corresponding C@MPUS groups.

Task Definition:
Within the framework of this teamwork, basic theoretical and practical knowledge in the fields of electrical machines and their control and regulation is to be acquired. There are two teams whose tasks are divided into two work packages (AP):

  • TEAM 1 - AP1: Winding and commissioning an EC motor
    Stator and rotor of electronic motor (EC-motor) are given. The stator must be suitably wound. The focus of the work is on the analysis of the given components, the winding scheme and the choice of the number of windings of the EC motor. In addition, the Hall elements must be suitably positioned to detect the position of the rotor.

  • TEAM 1 - AP2: FPGA programming
    The power electronics and the signal electronics for controlling the EC motor are provided. With the help of a Field Programmable Gate Array (FPGAs) a control or regulation for the EC motor is to be programmed. The FPGA must convert the control of the transistors of the pulse inverter depending on the evaluated Hall signals. Programming is done in the programming language AHDL.

  • TEAM 2 - AP1: Winding and commissioning an EC motor
    The winding process is the same as for Team 1 - AP1, commissioning is carried out using an electronic kit.

  • TEAM 2 - AP2: µC programming
    The power electronics and the signal electronics for controlling the EC motor are implemented with the aid of the electronics kit in AP1. With the help of an ATMEL microcontroller, a control system for the EC motor is to be programmed. The microcontroller must control the transistors of the pulse inverter and evaluate the Hall signals. Programming is done in the programming language C.

Topics from the lectures "Electric Machines I & II" and "Inductive Charging":

  • Modelling and simulation of an asynchronous machine in Matlab/Simulink (project work computer simulation)
  • Measurement of an asynchronous machine on the test bench
  • Control of an asynchronous machine on the test bench
  • Modelling and control of a permanent-magnet synchronous machine
  • Non-contact energy transmission

The trials will take place on Tuesdays and Thursdays, whereby 4 trials will take place on Tuesdays regardless of the regular weekday.

The registration is possible from 02.04.2018 at 08:00 o'clock, it ends on Wednesday, 11.04.2018.
During this period, students must register for the C@MPUS module "Praktische Übungen im Labor (M.Sc.) Elektromechanische Energiewandlung II" on the waiting list.
In addition the  registration form has to be completed an send via email to fachpraktikum@iew.uni-stuttgart.de.

The number of participants is limited to 20 students, the time of registration and the individual previous knowledge decide about a place in the internship. The group classifications will be announced by e-mail on Friday, 13.04.2018 and the admitted students will be assigned to the corresponding C@MPUS groups.

The following experiments are offered at IEW as part of the basic practical course for electrical engineers:

  • Identification of components such as ohmic resistance, coil, capacitor and diode using the current-voltage characteristic.
  • Behaviour of the components at direct voltage and at alternating voltage.
  • Application of measuring devices for current and voltage measurement.
  • Recording of a diode characteristic.
  • One-way rectification and smoothing of the rectified voltage.
  • Highpass and lowpass.

Campus Link

Three test blocks are planned:

  • AC/DC + Measurement
  • semiconductor devices
  • Electrical machines

Each test block is divided into several different problems, which are dealt with in groups of three. Each student completes a problem from each of the three blocks.
