A study on the ferromagnetic layer of a single-phase written-pole motor in consideration of demagnetizing field intensity
ABSTRACT This paper proposes the design methodology for a magnetic layer of a single-phase written-pole motor (WPM). Theory of WPM operation is explained and method of characteristic analysis is represented. For design of magnetic layer, the necessary B-H characteristics and mechanical dimension of ferromagnetic layer of the WPM are determined in consideration of demagnetization property, where the demagnetizing field intensity is calculated by the d-q circuit analysis.

ABSTRACT: This paper presents a dynamic model to simulate high-power single-phase "written pole" motors. The basis of the model is the generalized theory of electrical machines. From this theory, the required equations governing the dynamic behavior of these motors are obtained. Then, the equations are solved in a special reference frame that is valid for the unique properties of single-phase written pole motors. Comparison of simulation results of the model with experimental data shows very good agreement.IEEE Transactions on Magnetics 08/2004; · 1.42 Impact Factor
Conference Proceeding: Theory investigation of 3-phase Written-Pole® motors[show abstract] [hide abstract]
ABSTRACT: Analysis and design formulas of 3-phase Written-Pole™ motor are deduced with a 1D magnetic circuit method. The study of this machine is done by 3-dimensional finite element electromagnetic computation software. The 3-dimensional model of a 30 hp/3-phase motor is constructed and FFT analysed, which gives the amplitude and phase angle of the fundamental and harmonic components. Finite element (FE) computation to the model with electromagnetic software was used to check the ID magnetic circuit method Technical and economical possibilities to scale the power level of these devices down to 1 kW and up to the MW level are givenElectrical and Computer Engineering, 2002.
