  1. 1. Modeling and Analysis of PMSM with Turn-To-Turn Fault

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Joachim Härsjö; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic forces; vibration.; inter-turn; fault; fault detection; turn-to-turn fault; Permanent magnet synchronous machine PMSM modeling;

    Abstract : Thanks to its high-torque density and high efficiency, the Permanent Magnet Synchronous Machine (PMSM) is today used in a vast range of applications, spanning from automotive to wind. Since in a PMSM the excitation field is provided by a permanent magnet instead of a coil, this machine does not have a rotor circuit and thereby the risk for electrical failures can be isolated on the stator circuit.

  2. 2. Design and analysis of a fault-tolerant fractional slot PMSM for a vehicle application

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Christian Dubar; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Saturation; Permanentmagnet synchronousmachine PMSM ; Fault-tolerance; windings; Concentrated; Fractional slot; Unbalanced operation;

    Abstract : The permanent magnet synchronous motor (PMSM) is an interesting alternative for an electric motor drive system in automotive applications, due to to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density a PMSM can achieve since it is very important to save especially space but also weight in vehicle applications. READ MORE

  3. 3. A Permanent Magnet Traction Motor for Electric Forklifts : Design and Iron Loss Analysis with Experimental Verifications

    University dissertation from Stockholm : KTH

    Author : Yung-Kang Robert Chin; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Electrical engineering; electronics and photonics Electrical engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektroteknik;

    Abstract : This thesis presents the design analysis of a permanent magnet synchronous motor (PMSM) for the traction application in electric forklifts. Within the scope of the study, an existing induction traction motor for electric forklifts benchmarks the expected performances of the proposed PMSM designs, as design specifications. READ MORE

  5. 5. Thermal Design of Electrical Machines - Investigation and Evaluation of Cooling Performances

    University dissertation from Stockholm : Elektrotekniska system

    Author : Zhe Huang; Lund University.; Lunds universitet.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This Thesis focuses on thermal design of permanent magnet synchronous electrical machines (PMSM) used in hybrid vehicles (HEVs) or zero emission vehicles (ZEVs). Electrical machines in such applications are usually designed with high power density requirements but within limited spaces, which lead to high rate of heat generation but low rate of heat dissipation.
