“…There are examples about AC contactors that show waveforms of the currents in the main coil [8][9][10][11][12][13][14][15][16][17]. Generally, such waveforms are similar to the results obtained for this article; however, the current after the end of the armature displacement is not shown in one case [12], and the shown waveform is not conventional in another case [13].…”

“…However, some simulation details for the contactors are only described in specialized studies, for example, the nonlinear effect due to the limits for the armature displacement [6,7], the discontinuities in the armature path due to the changes in the springs and masses in motion [8,9], and the effects of the small air gaps between armature and core when the contactor is closed [9].…”

“…The objective of the shading rings is to obtain a phase shift between two magnetic fluxes in the armature in order to always achieve an instantaneous net force greater than zero on the armature, because this avoids the mechanical vibrations that would be produced without these shading rings. Different studies give diverse details about the simulation of contactors with an AC coil and shading rings [8][9][10][11][12][13][14][15][16][17] by using the finite-element method [8][9][10][11][12][13] or without using it [14][15][16][17].…”

Two ways of modeling a contactor with an AC coil are shown in this article. Both models are based on the explicit definition of the inductances by lumped parameters, and the difference between them is the considering or not of the effect of the shading rings. The equations were formulated to obtain the contact operation time and to describe the contactor coil current when the coil is fed with different values of the AC source voltage. The comparison between theoretical and experimental results shows that the models are satisfactory in both cases. This demonstrates the possibility of obtaining accuracy without considering the shading rings. The main advantage of the inclusion of the effect of the shading rings is the obtaining of a qualitative description for the currents in the shaded rings.

“…The design and analysis of linear electromagnetic devices, such as electromagnetic valves [21], electric tools [22], oscillators [23,24], and switch gears [25][26][27], are mainly carried out by the finite element method (FEM). Likewise, aiming to satisfy the need to accommodate the clutch in the limited space available in the hub, the optimal design of the main structure parameters of the PMBECU are carried out by FEM which focuses especially on investigating the leakage flux coefficient of the PM.…”

Abstract:Clutches have been used in internal combustion vehicles and concentrated electric vehicles (EVs) to smoothen impulsion while starting and shifting. This paper proposes a permanent magnet bi-stable electromagnetic clutch unit (PMBECU) which is specially introduced into in-wheel EVs to make the rigid connection between hub and wheel more flexible. Firstly, the operation principle of the PMBECU is illustrated. Then, the basic magnetic circuit model is presented and analyzed, followed by optimal design of the main structural parameters by investigating the PM leakage flux coefficient. Further, according to the basic electromagnetic characteristics of the PMBECU, the current pulse supply is put forward, and the minimum pulse width which enables the operation of the PMBECU and its dynamic characteristics are analyzed by an improved finite element method. Finally, a prototype machine is manufactured and tested to validate all the analysis results.

Unigraphics NX (UG NX) software is mechanical engineering aided design system development America UGS a set of CAD / CAM / CAE in one. UG originated in USA McDonnell Douglas Aircraft Company, later merged in 1991 into the world's largest software company --EDS. Widely used in electronics, aviation, automobile, household appliances, toys and other industries. By modeling the characteristics of UG based entity, has the dimension driven editing and unified database. The core of parasolid provides powerful modeling software and seamless data conversion ability, digital model of UG established capable of data conversion in a variety of software, and provides convenience for data exchange.Keywords: CAD/CAE/CAM software, CJX2-40 type AC contactor, dynamic simulation ESTABLISHING THE VIRTUAL PROTOTYPING OF CONTACTOR MECHANICAL SYSTEMThe modeling features of UG: UG provides a very flexible composite modeling methods, it realizes the association and shared between all relevant and digital entity modeling data for users to edit graphics is very convenient. Such as solid modeling (Solid), surface modeling (Surface), the wire frame modeling (Wireframe), feature modeling and realistic photographic powerful rendering [1], animation and rapid prototyping tool based on. The user can mix various modeling method according to actual needs, fully display its superiority modeling, UG users can quickly and accurately the tolerance feature will feature information of tolerance and geometric objects associated, so that you can on the assembly model analysis.UG software in the design of software has a great advantage in the aspect of modeling, management and development. Through the software understanding, general characteristics are: desktop style is very simple; the main model can conveniently inquire into the parameter expression; tree management style history, can easily query to the entire modeling step; a strong hint function for modeling process, every step has clear indication; software has development, provides two times the development of means, provides convenience to meet different needs of enterprises [2].Unigraphics works in the product development the most competitive victory in the MACD industry, compared the characters and functions of UG, has many unique features, such as: Unigraphics provides a powerful programming framework, so that customers and suppliers of software applications can be developed with UG very good integration and complete relevant, personalized the program can continue to add users. In the machinery industry, the most closely to CAD/CAM/CAE integrated with PDM, the formation of the whole design, analysis, processing, management integration of a high level of software. In the extended enterprise customers the meaning of the data can be converted to each other, even including those input data is the problem of the high rate of success of intelligent conversion etc.. UG software into China for more than 20 years, has been widely recognized by Chinese enterprises, has become one of the main use...
