1. 1. Commissioning of a FPGA/DSP unit for Centralized Control of a Variable Phase Pole Multiphase Machine

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jonas Hansson; [2022]
   Keywords : Harmonic Plane Decomposition; Multiphase Electrical Machine; Wound Independently-Controlled Stator Coils; System on a chip; Control Implementation; Hardware Design ; Motorstyrning; Asynkronmotor; Multifasmaskin; Programmering; Systemkrets; Hårdvarukonstruktion;

   Abstract : Multiphase Electrical Machines (MPEMs) with variable phase-pole configurations have recently gained interest as it offers advantages such as a larger operating range and improved fault tolerance compared to more traditional MPEMs. The current state-of-the-art modeling and control method, Vector Space Decomposition (VSD), has the drawback of introducing discontinuities in the model when transitioning from one phase-pole configuration to another.

3. 2. Condition monitoring of induction machines using a signal injection technique

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Sathiya Lingam Senthil Kumar; [2020]
   Keywords : Condition monitoring; fault detection; fault diagnosis; stator winding fault; inter-turn fault.; Tillståndsövervakning; feldetektering; feldiagnos; statorlindningsfel; kortslutning mellan varv.;

   Abstract : Condition monitoring techniques can be employed to enhance reliability of electric machinery. The stator winding fault is one of the dominant causes for the failure of induction machines. In this work, the condition monitoring of an inverter-fed induction machine using high-frequency signal injection based technique is investigated. READ MORE

4. 3. Finite-element analysis of an induction motor with inter-turn short-circuit faults

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Hareesh Babu; [2020]
   Keywords : Finite element analysis; stator winding fault; inter-turn short circuit.; Finit-element analys; statorlindningsfel; kortslutning mellan varv.;

   Abstract : Stator inter-turn short circuit (ITSC) faults are one of the common sources for induction machine failure affecting their reliable operation. In this thesis, a finite element (FE) model is developed to study the ITSC fault. The FE model is developed for a prototype induction machine that has the potential to emulate an ITSC fault in the stator. READ MORE

5. 4. Experimental Comparison of Losses in a Grid-connected and M2C-fed 11kW Induction Motor

   University essay from KTH/Elektrisk energiomvandling

   Author : GUSTAV MÖRÉE; [2015]
   Keywords : power losses; electric machines; AC-machines; induction machines; harmonic content; iron losses; modular multilevel converter M2C ; effektförluster; elektriska maskiner; AC-maskiner; asynkronmaskiner; övertonsinnehåll; järnförluster; modulär multinivå omvandlare M2C ;

   Abstract : This thesis analyzes the power losses in induction machines and how the losses depend on the harmonic content of the applied voltages. Two cases are compared, one case where a machine is fed with a sinusoidial voltage and one case with a modular multilevel converter (M2C). READ MORE

6. 5. Design of a Synchronous Reluctance Motor Assisted with Permanent Magnets for Pump Applications

   University essay from KTH/Elektrisk energiomvandling

   Author : Adrian Ortega Dulanto; [2015]
   Keywords : Demagnetization study; efficiency; FEM; parametric study; Permanent-Magnet Assisted Synchronous Reluctance Motor; prototype;

   Abstract : This Master thesis focuses on the design of a high efficiency Permanent-Magnet-Assisted Synchronous Reluctance Motor (PMASynRM) intended for pump applications. The new motor is designed to replace an existing Induction Motor (IM) in a pump product. The basic principles of SynRM, and PMASynRM Motors and a good analytical model were introduced. READ MORE
