Design of Halbach-Array-Based Permanent-Magnet Motors With High Acceleration
IEEE Transactions on Industrial Electronics, 2011The Halbach magnetized permanent-magnet (PM) motors can be designed to achieve high torque density and to realize hollow rotor structure with very low rotational inertia. In this paper, the design and analysis of Halbach-array-based PM motors, which can produce high output torque and meet the requirements for very fast dynamic performance, are ...

IEEE Transactions on Magnetics, 2019
This paper presents an analytical model of magnetic field of a permanent magnet synchronous motor (PMSM) with a trapezoidal Halbach permanent magnet array (THPMA). Compared with conventional Halbach array, the shape of each magnet in THPMA is transformed from rectangle to trapezium in polar coordinates.

Calculation of the Static Forces Among the Permanent Magnets in a Halbach Array
IEEE Transactions on Magnetics, 2009This paper concerns the analysis of the interaction force among the permanent magnets (PM) in a Halbach array as used in a moving-magnet planar actuator. The goal is to analyze the magnitude of these forces and to what extent the mechanical construction of an aluminium plate, on which the permanent magnets are mounted, is deformed by the interaction ...

Optimization Analysis Model of Halbach Array Permanent Magnet Motor
2020 5th International Conference on Smart Grid and Electrical Automation (ICSGEA), 2020It is generally assumed that the stator core and rotor core are infinitely permeable in conventional analysis methods. Therefore, magnetic saturation is easily overlooked and the magnetic flux density is overestimated. This article introduces the analysis model of a permanent magnet (PM) machine with a segmented Halbach array (PMMSHA). It considers the
