“…Son yıllarda ise, daha yüksek binalarda klasik üç fazlı makinaların ihtiyacı karşılayamaması durumu göz önünde bulundurularak çok yüksek hızlı motor sürücü sistemleri hakkında çalışmalar yapılmıştır [5]. Farklı çalışmalarda, sargı diyagramları tasarımına, farklı faz sayısına sahip motor tiplerine ve sürücü sistemlerine dair çalışmaların yanı sıra, daha kaliteli malzeme kullanımı da gerek mıknatıs gerekse çelik tercihi göz önünde bulundurulmuştur [6]. Böylece, verim ve performans açısından daha detaylı çalışmalar ortaya konmuştur.…”

2 Metroplast Asansör, Iran Highlights: Graphical/Tabular Abstract • Analysis of permanent magnet synchronous motors in different structures used in elevator applications • Analytical calculation, analysis with finite element method and production process, consistency with the test results • Making a new design with increased efficiency, decreased the size, volume and weight of the motorIn this study, low speed and high torque permanent magnet synchronous motors (PMSM) used in elevator applications are investigated. Better motor design solutions are proposed by using the analytical calculations, the finite element method based simulations. Firstly, a permanent magnet synchronous motor having 60 slots 16 poles (already in the market) for an eight-person elevator which is operating at a speed of one meter per second is analyzed by using the simulation and experimental results. The simulations of the motors having 48 and 54 slots are performed as the next step. Different types of motors have been analyzed in terms of current, voltage, harmonic components, moment and efficiency characteristics. In the view of these results, the most suitable motor is prototyped considering the cost and the relevant standards for the elevator applications. The proposed new motor with 54 slots shows a better performance due to its simulation and test results by increased efficiency and decreased the size, volume and weight. This is valid even though better permanent magnets are preferred. In addition, the stack length of the new motor is reduced by 20% and this output is very important especially for elevator applications.

“…GO electrical steel is also used in stator cores of large rotating electrical machines to increase the efficiency and power density made possible by its high permeability and specific total loss compared with that of more commonly used non-oriented (NO) electrical steel. In such cases GO steel laminations are cut into segments of a stator core, where the teeth directions in each segment are usually aligned close to the RD of the steel [16,17]. Thus, the core back-iron is mainly aligned close to the transverse direction (TD) of the laminations.…”

Magnetostriction is an important source of vibration and acoustic noise in electromagnetic cores. This study reports magnetostriction components along the rolling, transverse and magnetisation directions (MDs) of grainoriented (GO) electrical steels, used for transformer and large rotating machine cores, under magnetisation at angles to the rolling direction (RD). Magnetostriction components in the sheet plane were simultaneously measured using a twodimensional magnetisation system. Results from the measurements agreed with the magnetostriction calculated from a simplified model of magnetic domain patterns in a 3% SiFe single crystal. It is shown that the magnetostrictive strain along the RD is always the highest component in the sheet plane irrespective of MD. This is expected to cause both additional vibration at the corners of transformer cores where flux deviates from the RD and high radial vibration in the back-iron regions of rotating machine stator cores assembled from segmented GO steel laminations.

“…Recent trends in system automation include the development of custom electrical actuators, whose different mechanical, electrical, and sometimes electronic components are designed by an integrated approach strictly related to the requirements of the specific application [1] [2]. Often, the electrical actuator is developed to replace hydraulic or pneumatic actuator inside a pre-existing machine: in these cases the main design enforces are oriented to satisfy both the performance and the encumbrance limits.…”

This paper presents the design concepts and the test results of a Permanent Magnet synchronous motor (PMSM) for an electro-mechanical actuator used in high-performance sheet metal bending machine. The motor is directly integrated with the mechanical component in a rotating-ballscrew architecture in order to minimize the total inertia and the actuator's size. The motion trajectory fits the classical profile with high-torque at low-speed and low-torque at high speed, which involves flux-weakening operation. A prototype has been manufactured using the design data of the optimization procedure. Due to mechanical considerations and the encumbrance limits, the proposed motor has the PMs directly glued on the surface of the steel nut that represents the "rotor".Test results confirm the performance of the system and the goodness of the prototype.
