16. Performance Analysis of Unskewed Asymmetrical Rotor for LV Induction Motors
University essay from KTH/Elektrisk energiomvandlingAbstract : This master thesis presents a comparative analysis of the starting performance and losses at rated operation for a 15 kW, 4-pole industrial induction motor, mounted with standard skewed, unskewed and unskewed asymmetrical die-cast aluminium rotors through measurements and simulations. It is a well-known fact that rotor skewing suppresses the synchronous torques at low speeds and also reduces the audible noise of the machine. READ MORE

17. FPGA Implementation of a DB – DTFC Scheme for Induction Machines
University essay from Lunds universitet/Industriell elektroteknik och automationAbstract : Induction machines have been used in a wide range of applications due to its robustness and its low price. These characteristics make the induction machine a suitable option for industrial and home environments especially for those applications where the required speed is constant and the load does not change drastically.

18. Sensorless control of induction machines, in railway applications
University essay from KTH/Elektrisk energiomvandlingAbstract : In this master thesis, a sensorless system has been developed for an induction machine in railway applications. The approach which was taken in this master thesis is a consequence of the expectations of the company: investigate thepossibilities of having the current generation of Alstom's drive system working without use of a speed sensor.
