1. Fault diagnosis of a variable pole-phase motor
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Wound Independently Controlled Stator Coil (WICSC) machines are a novel type of multiphase machine with the ability to change its pole-phase configuration during operation. This enables improved post-fault control and thus prolonged continuous operation. READ MORE

2. 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)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. Development of an experimental six-phase induction machine drive
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. READ MORE

4. Online Parameter Estimation of a Six- Phase Machine for Marine Application
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. READ MORE

5. Analysis of Different Switching Patterns to Minimize Losses in a Six- Phase Drive for Marine Application
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Multiphase machines have gained a lot of popularity during the recent years, as they offer certain benefits over their three- phase counterparts. This work investigates the losses of a six- phase drive system for a marine application when supplied by four different switching patterns (also referred to as modulators). READ MORE
