“…Because of the finite length of the motor the impedancesZ i are slightly different, so that the currents in the windings are not able to produce the same magneto-motive force as that produces by (6). At a first approximation we can neglect this error which decreases with the length of the motor and its number of pole pairs.…”

“…The simplest approach to model these linear motors is based on the use of lumped equivalent circuits as described in [1][2][3][4][5][6][7] for similar devices. However, while this technique allows to establish analytical relationships between the design parameters and the performance of the machine, it suffers from inherent inaccuracy especially in presence of complex flux paths.…”

Abstract-In this paper, some design criteria for a Tubular Linear Induction Motor (TLIM) as a fast actuator are considered. The influence of geometrical and physical parameters on the operating conditions of a TLIM are investigated by means a quasi-analytic model. The model is based on the application of the Fourier Transform both in space and in time. The Fourier transform in space is introduced to take into account the finite length of the stator windings in the axial direction. The transient electrical response of the motor at standstill following the insertion of a three-phase system of voltage generators is performed by the Fourier transform in the time.

“…The lumped equivalent circuit is the simplest approach to model the magnetic field, and allows to establish analytical relationships between design parameters and output performance. However, the technique suffers from inherent inaccuracy especially in presence of complex flux paths [22]. The mesh-based equivalent circuit is developed to achieve higher accuracy through a division of geometry [23].…”

Abstract-Permanent magnet (PM) array affects flux field distribution of electromagnetic linear machines significantly. A novel dual Halbach array is proposed in this paper to enhance flux density in air gap, and thus to improve output performance of linear machines. Magnetic field in three-dimensional (3D) space of a tubular linear machine with dual Halbach array is formulated based on Laplace's and Poisson's equations. Numerical result from finite element method is employed to simulate and observe the flux distribution in the machine. A research prototype and a testbed are developed, and experiments are conducted to validate the analytical models. The study is useful for analysis and design optimization of electromagnetic linear machines.

Abstract-The thermal characteristic of a new out-rotor fault-tolerant permanent-magnet (FTPM) motor is modeled and predicted in this paper. Flow characteristics and thermal characteristics of this FTPM motor are calculated by using computational fluid dynamics method. The key is that an equivalent model is developed to replace the real motor, offering the merits of simplified meshing progress and convenient thermal calculation. Furthermore, the effectiveness of the developed equivalent model has been verified by simulation and experiment. In addition, the temperature distribution of the entire motor is given by using equivalent models. The results can be provided to improve motor thermal performance.
