“…Среди зарубежных публикаций последнего вре-мени встречаются работы, посвященные разработкам двухстаторных вращательно-линейных электромеха-нических преобразователей, которые способны вра-щать и перемещать вдоль своей оси (Amiri, 2014). Такие устройства привлекают к себе все больший интерес и обычно встречаются в таких процессах, как бурение, перемешивание, нарезание резьбы, завинчи-вание, приведение в действие роботизированных устройств.…”

Purpose. Determination of the effect of perforations in the hollow ferromagnetic rotor on dynamic characteristics of the electro-mechanical transducer.Methods. Calculation of the dynamic characteristics of the electromechanical transducer with a hollow smooth and perforated rotor was performed using the theory of the general electrical machine, as well as the numerical solutions of differential equations by finite elements' method in three-dimensional statement.Findings. The paper presents the research into the impact of rotor holes on the form of dynamic characteristics, which was carried out on the basis of comparing characteristics of the electromechanical transducer with those of smooth and perforated rotor. Introduction of rotor perforations brings about downward transposition of the mechanical dynamic characteristic parallel to itself. Starting the transducer with hollow ferromagnetic rotor, compared to starting the basic asynchronous motor, has a lower amplitude and smaller number of pulsations of electro-magnetic shock torque. We suggest calculating the dynamic characteristics of the electromechanical transducer with a hollow ferromagnetic rotor by way of combining the generalized theory of electrical machines with numerical solution of finite elements' method in three-dimensional statement. This approach was tested by juxtaposing the calculated and experimental data obtained for the physical model of the transducer with a hollow ferromagnetic rotor.Originality. Dynamic characteristics of the electromechanical transducer with a hollow smooth and perforated rotor were obtained for starting with ventilation load. Practical implications.The study results allow to expand the scientific theoretical basis of asynchronous machines with a ferromagnetic rotor and can be used to optimize the design and improve the efficiency of implementing electromechanical transducers with a hollow perforated rotor.

“…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.

“…The transient time-domain finite-element model and frequency-domain slip frequency technique were combined to analyse the dynamic end effect generated by linear motion on both linear and rotary armatures [13]. The equivalent circuit model of the motor was proposed, which took into account the static end effect in the linear armature and the dynamic longitudinal end effects occurring at both rotary and linear armatures during the helical and linear motion [14]. The 2DoF direct-drive induction motor (2DoFDDIM) is another 2DoF induction motor in which the stator is composed by two arc-shaped stators [15].…”

Two-degree-of-freedom motors are capable of producing linear, rotary, and helical motion, and thus have widespread applications in special industries. In this paper, a new concept-static coupling effect-is studied in the 2-degree-of-freedom direct drive induction motor (2DoFDDIM). The proposed approach is based on the image method and the 3D finite element method. The image method model is established to analyse its reasons and predict the main effects, which are then verified by the proposed 3D finite element static coupling model and experiments. The induced voltages and currents are produced in the static part and induced torque or force is obtained, even though the static part is not energized. It is concluded that the static coupling effect increases with the supply frequency and is influenced by the stator winding configuration. Thus, the existence of the static coupling effect is confirmed, which must be taken into account in future optimization and precise control of the 2DoFDDIM.Index Terms: induction motor, image method, static coupling effect, 3D finite element method, 2-degreeof-freedom.
