Design and performance analysis of magnetic slot wedge
slots is proposed to reduce the capacity demand of rotor converter for the first time. The proposed method is achieved by decreasing the air-gap length (AGL) and applying conductive and
Design principle of a 16‐pole 18‐slot two‐sectional
In this paper, a 16-pole 18-slot single-sided PMLSM is studied. The two-sectional modular structure is used on the primary to suppress the end detent force, as shown in Fig. 1. The secondary structure consists of some

Analytical Solution of Air-Gap Field in Permanent-Magnet
9-slot PM motor, assuming that in the slot opening regions the results contain normally distributed errors with zero mean and a standard deviation being 5% of the local flux density ampli-
Effect of Stator Slots on Electromagnetic Performance
In this paper, the effect of a stator slot on the distribution and the amplitude of the magnetic field at no-load are investigated. Taking a 630 kW HVLSPMSM as a case study, the influence of the stator slot and a MSW on
Magnetic Slot Wedge Application Analysis in Double-fed
To eliminate high order space harmonics in double-fed asynchronous motor-generator, magnetic slot wedge application is introduced. A field-circuit finite element analysis model is proposed
Research on Synergistic Reduction of Cogging Torque
This paper presents a method for reducing the cogging torque and ripple torque of interior permanent magnet synchronous motor (IPMSM) based on the magnetic field harmonic offset method. This method establishes

Understanding Magnetic Field Energy and Hysteresis Loss in Magnetic
Both electric fields and magnetic fields store energy. The concept of energy storage in an electric field is fairly intuitive to most EEs. The concept of magnetic field energy,
Novel Magnetic Field Modeling Method for a Low
