  5. 18. Permanent-Magnet Synchronous Machines with Non-Overlapping Concentrated Windings for Low-Speed Direct-Drive Applications

    Author : Florence Meier; Juliette Soulard; Zi-Qiang Zhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electronic engineering; electrical engineering; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract :  Many geared electric drives can benefit from removing the gearbox and driving directly the load at low speed using a permanent-magnet synchronous machine (PMSM). PMSMs with non-overlapping concentrated windings are particularly attractive in low-speed direct drives since they allow, among other advantages, a high number of poles with a limited number of slots.

  6. 19. Design of a fault-tolerant fractional slot PMSM for a vehicle application

    Author : Christian Dubar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PMSM; Efficiency; Fault-tolerant; Unbalanced operation; Saturation; Fault-tolerance; Fractional slot; Permanent magnet synchronous machine; PMSM ; Concentrated windings;

    Abstract : In automotive applications, the PMSM is an interesting alternative due 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 since it is very important to save especially space but also weight in vehicle applications. READ MORE
