Effect of parameters on back-EMF in permanent magnet brushless DC motor with concentrated winding
A method for analyzing the concentrated windings back-EMF in permanent magnet brushless DC motor, based on the analytical calculation of one phase back-EMF by using Fourier series, has been developed and validated by comparing computing waves to measured waveforms. And the paper discussed the influence on back-EMF of design parameters.
Development of EPS rare-earth permanent-magnet brushless direct current motor
This paper analysis the design characteristics of brushless direct current motor (BLDCM) in the electric power steering system; introduces a new type of built-up stator core permanent-magnet BLDCM, together with the trial manufacture of the BLDCM.
Development and Application of Rare Earth Permanent Magnet Electrical Machines
China is abundant in rare earth resource and becomes the center of global magnet industry of 21st century,so it is more conveninent and favorable to develop rare earth permanent magnet electrical machines(REPMM) in China.In this paper,a brief introduction of the advantages,market prospects,direction and achievements of the research and development of the REPMM as well as a brief account of the development of NdFeB permanent magnets for the REPMM is presented.
