A novel PM motor with hybrid PM excitation and asymmetric rotor structure for high torque performance

This paper proposes a novel permanent magnet (PM) motor for high torque performance, in which hybrid PM material and asymmetric rotor design are applied. The hybrid PM material is adopted to reduce the consumption of rare-earth PM because ferrite PM is assisted to enhance the torque production. Meanwhile, the rotor structure is designed to be asymmetric by shifting the surface-insert PM (SPM), ...

Investigation on Slot–Pole Combinations of a PM Vernier Motor with Fractional-Slot Concentrated Winding Configurations

This paper presents a new method to find available slot–pole combination of a permanent magnet (PM) vernier motor with fractional-slot concentrated winding (FSCW) configurations instead of the conventional design rule. To this aim, for a common structure of PM vernier machines with FSCW, the air gap flux densities including modulation flux due to vernier effects are investigated from the magnet...

Influences of Winding MMF Harmonics on Torque Characteristics in Surface-Mounted Permanent Magnet Vernier Machines

This paper presents the influences of winding magneto-motive force (MMF) harmonics on the torque characteristics in surface-mounted permanent magnet vernier (SPMV) machines. Based on the magnetic gearing effects, the armature magnetic field of the SPMV machines is modulated by flux modulation poles (FMPs). In the modulated magnetic field, a working harmonic which corresponds to the number of th...

Cogging Torque Minimisation of PM Disc Motor by Inserting Stator Slot Closure and Magnet Skewing

A variety of techniques exist for reducing the cogging torque of conventional radial flux PM machines. This paper presents an application of two cogging torque minimization techniques in which the permanent magnets are skewed in a conventional manner and the stator slots are closed with soft magnetic composite material. The comparative analysis of the different motor designs regarding the coggi...

Influence of Design Parameters on the Starting Torque of a Single-Phase PM Brushless DC Motor

The starting torque of a single-phase permanent magnet brushless dc motor is investigated, for both radial and parallel magnetization. Finite element analysis is used to assess the relative merits of alternative methods of introducing the required airgap asymmetry, viz. tapered airgap, stepped airgap, asymmetric airgap, and slotted teeth. The predicted results are validated experimentally.
