The master thesis aims to develop an electric drive system controlling a specic type of electric machine. A part of the master thesis has been to evaluate and analyze whether the proposed machine can perform the desired tasks for this system. The machine has also been analyzed and measurements has been performed. The electric drive unit should control the machine as both a motor and a generator. An electric drive system prototype has been developed and manufactured, also an implementation of control algorithms has been made in a microcontroller. The prototype can control the machine in both motoring and generation. The performance of the system has mostly been evaluated in terms of torque and rotational speed. Such high speeds that were desired for the function of the system was not reached. Improvements and alterations to the system in order to fulll the desired specications is proposed an the possibilities to use the specic machine is discussed.
