“…A three-dimensional analysis of a rotational-linear converter, which considers the longitudinal and transverse edge effects, the current displacement effect, the influence of the thickness of the core outer sheets, and which practically has no restrictions on the magnetic circuit configuration, is presented in the publication (Alwash & Qaseer, 2010). In the works (Mendrela, 1978;Fleszer & Mendrela, 1983;Cathey, 1985;Mendrela & Geirczak, 1987;Rabiee & Cathey, 1988), the analysis of an asynchronous converter with spiral motion is given. The authors use the Fourier method of series, which takes into account edge effects.…”

Purpose. Creating a three-dimensional mathematical model of the electromagnetic field of an auger electromechanical converter with the external solid rotor, taking into account the geometry peculiarities and the finite length factor. Methods. Calculation of the electromagnetic field distribution has been performed with the use of the computational solving the differential equations by the finite element method in a three-dimensional statement.Findings. It has been set that in the air gap the values of magnetic induction vary in the range of 0.7 -0.8 T, in the flanks of the stator teeth they reach the value of 2 T. Induction in a hollow ferromagnetic rotor varies mainly in the range of 1.3 -2.0 T, and in a thin layer with a thickness of 1.0 -1.5 mm, facing the stator surface, it reaches the value of 2.3 T. Within one pole pitch, the z-component maximum of the eddy currents density is 18ꞏ10 6 A/m 2 on the inner hollow rotor surface. It has been determined that, with the exception of the 'edge' rotor sections, where the transverse component of eddy currents prevails, as well as the sections of the magnetic flux "input" into the rotor, the eddy currents are mainly axial. A comparison of the results of measuring the electric field intensity on the rotor surface evidences a data difference of not more than 4%. The proposed model enables to optimize the design of the converter, in particular, to reduce the magnetic induction in the stator teeth.Originality. Numerical results have been obtained in the form of spatial patterns of distribution and graphical dependences that take into complete account the axial and tangential components of the electromagnetic field. Practical implications.The considered finite element model can be used when analysing the electromagnetic fields in electromechanical converters with a complex secondary part. This will give a possibility to consider the real threedimensional field character, caused by the design peculiarities and the final axial dimensions.

“…To address this problem, a single-armature induction LRM is proposed, which features a single stator and two groups of windings and can realize multidimensional motion in Mendrela and Gierczak. 10 However, this structure also has serious magnetic field coupling since both groups of windings share stator slots. Overall, while single-armature LRMs offer a compact structure and high integration, the severe magnetic field coupling effect exacerbates energy coupling behavior and increases the difficulty of modeling and control.…”

“…However, the severe energy coupling behavior between the traveling wave magnetic field and the rotating magnetic field restricts the above‐mentioned single‐armature LRMs to only perform helical motion, and not linear or rotational motion.

SummaryThe energy coupling behavior is propagated through the magnetic field and would seriously affect the operation performance of two‐degree‐of‐freedom motion system based on linear‐rotary motor. This paper proposes a novel double‐stator linear‐rotary switched reluctance motor (DSLR‐SRM) to suppress the energy coupling behavior. First, the structure and operation principles of DSLR‐SRM are presented. The two stators of DSLR‐SRM are radially arranged to perform the independent magnetic circuit and suppress the energy coupling behavior through the magnetic field. Then, an equivalent circuit model is established to shorten the modeling and calculation time. It could be found that the energy coupling behavior directly affects the torque and force performance. Next, the sensitivity of the DSLR‐SRM dimensions is developed. Meanwhile, the dimensions of DSLR‐SRM are optimized to enhance the torque and force output via TOPSIS decision‐making. Finally, the validity of equivalent circuit modeling analysis and optimization results are verified through three‐dimensional finite element model.

“…The conventionally complicated structure comprising of a linear motor and a rotary motor can be substituted by one 2Dof motor, which greatly simplifies the system. A few different topologies of 2DoF motors have been proposed and investigated by researchers [2][3][4][5][6][7][8][9][10]. For example, a 2DoF outer rotor spherical actuator [7] and a novel magnetisation pattern [8] have been presented for 2DoF rotary-linear actuators.…”

Abstract-This paper presents a composite multilayer method (CMM) to evaluate the performance of a two-degree-of-freedom (2DoF) direct drive induction motor (2DoFDDIM) whose solid rotor is coated with a copper layer. It includes a rotary part and a linear part. Based on the traditional multilayer theory, a complete 2DoFDDIM CMM computer program importing propagation constants is built. Due to the complex magnetic field in a 2DoFDDIM, this paper mainly analyses it from the perspective of a single DOF motor. An equivalent circuit for the rotary part of the 2DoFDDIM is then derived applying CMM and the two-dimensional magnetic field distribution is obtained by solving Maxwell's equations in motor layers.
