This paper provides the comparative analysis of coreless-type permanent magnet linear synchronous machines (PMLSM) with non-overlapping windings. The comparative study is carried out on the basis of conductor winding factor. In order to aid the comparison, the new factor called thrust factor is introduced to denote the best Spp family depending on the variation of coil width ratio. From the extensive...
The objective of this paper is to investigate the electromagnetic design aspects of a novel flux-switching motor-compressor with rotor poles designed as airfoils to perform compression. The proposed novel flux-switching motor-compressor is both an electric motor as well as an axial-flow compressor. Conventional motor-driven compressor system typically requires an electric motor and a gear box to connect...
The goal of this paper is to design and analyze the electromagnetic performance and thermodynamic performance of a high-speed integrated motor-compressor. The integrated motor-compressor is designed based on the flux-switching permanent magnet (FSPM) machine topology. The rotor poles of the proposed integrated motor-compressor are shaped into airfoils, and the proposed machine can produce electromagnetic...
The aim of this paper is to investigate the pole (2p) and slot (Qs) number combinations with concentrated windings to yield a minimum electromagnetic noise resulting from vibration mode order and torque variation. Preferentially, a novel method of finding possible pole and slot number combination is provided based on the new factor, i.e., Ccw called key winding factor. In addition, the relationship...
This paper presents the analytical method for analyzing the electromagnetic noise in fractional slot permanent magnet (PM) motors. The electromagnetic noise is mainly caused by the radial force and the torque variation. On load condition, the radial force density can be evaluated by integrating the open circuit magnetic and the armature reaction field using the conformal mapping and the winding function...
This paper presents a closed-form design optimization of surface permanent magnet (SPM) machines using concentrated windings layout. Over the last few years, the interest in the use of SPM machines with a high pole number for low speed direct-drive applications has significantly increased. In this paper, the analytical design model is developed and particle swarm optimization (PSO) is applied for...
