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

    Author : Simon Lundberg; [2022]
    Keywords : High-frequency signal injection; Permanent Magnet Synchronous Motor; sensorless speed control; Synchronous Reluctance Machine; square-Wave injection; Fyrkantsvågsinjektering; högfrekvent signalinjektering; Permanentmagnetsmotor; sensorlös hastighetskontroll; synkron reluktansmotor;

    Abstract : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. READ MORE

  2. 2. Investigation of Sensorless Control of Permanent Magnet Synchronous Motor Using High Frequency Injection

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Lucas Bergstrand; [2020]
    Keywords : ;

    Abstract : This thesis implements and analyses a sensorless control method for permanent magnet synchronous motors. The purpose is to investigate if the results presented in a study performed by Millinger et al. can be replicated on an industrial grade embedded control system. READ MORE

  3. 3. 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
