“…The Permanent Magnet Linear Oscillating Motors (PMLOMs) are one of the derivatives of the linear motors in the low power applications having the advantages of higher efficiency. They can be supplied with dc or ac voltages [4]- [7] of which, the dc motors are having better efficiency due to the absence of the core losses.…”

“…Therefore, determination of these parameters is essentially required for analyzing the machine model. There are several works [6], [9] executed which assumes the machine inductance to be constant for simplicity of the model although different other works [4], [7]and [8] dynamically estimate the inductance through FEM and field analysis and control [10][11][12][13][14][15] for getting correct results. In this paper, the machine under consideration is an axial flux machine and the mover is having a non-magnetic structure, which is aluminium.…”

Active magnetic bearings (AMB) are well-known components for the suspension of mechanical objects. The hybrid thrust magnetic bearing (HTMB) with permanent magnet creating bias flux and subsidiary air gap in this paper is used to save energy, and two opposing electromagnetic poles allow control forces in two directions and take account of linearizing effects. The flux distribution is affected by the control voltage and the permanent magnets for the HTMB. Accurate analysis and efficient optimal design are essential to avoid costly trials. The dynamic performances of the HTMB with subsidiary air gap are analyzed. The flux distribution at different time in the HTMB is shown, and the time variation of the magnetic force, the displacement of the thrust plane, the speed of the thrust plane are given respectively in case the voltages are 15V, 20V, and 28V. The inductance of the thrust magnetic bearing is calculated for each position. The described method can simulate the dynamic behavior of the AMB with permanent magnets. It enables design optimization of sophisticated AMBs by extensive parameter studies.Keywords-thrust magnetic bearing with permanent magnets; flux density; magnetic circuit; finite element method(FEM); dynamic response

“…In [6,7] magnetic field analysis for tubular motors has been presented for mostly flat induction motors. In [5,8,9] the field circuit models have also been applied for simulation of dynamic characteristics of the tubular motors. However, the investigations did not include the permanent magnet axial flux type linear oscillating motors (PMLOMs).…”

“…The d.c. motors are having negligible core losses and therefore show higher efficiency than the a.c. ones, although the a.c. motors are employed in many applications [3]. The a.c. motors are used in pumps and many linear actuators [5]. The linear oscillating motors (LOMs) differ in terms and technologies as well as construction [3] from their rotating counterparts.…”

The design, analysis, and control methodology of an energy efficient and high force to weight ratio rare earth N42 NdFeB based permanent magnet linear oscillating motor has been described. For this axial flux machine the mover is consisting of Aluminium structure embedded with rare earth permanent magnets of high energy density. Microcontroller based drive is developed for frequency and thrust control of the machine. Finite element method using FEMM is employed for analysis of various performance parameters of machine. The same parameters are also compared with the measured ones, which yields a good agreement to the proposed design.
