Ansoft ships industry's first electromechanical system simulator for design engineers.PITTSBURGH--(BUSINESS WIRE)--Oct. 16, 1995--Ansoft Corp., the leading supplier of electromagnetic field electromagnetic field Property of space caused by the motion of an electric charge. A stationary charge produces an electric field in the surrounding space. If the charge is moving, a magnetic field is also produced. A changing magnetic field also produces an electric field. simulation-based electromechanical The use of electricity to run moving parts. Disk drives, printers and motors are examples. Electromechanical systems must be designed for the eventual deterioration of moving components that wear over time. The first TVs were electromechanical systems (see video/TV history).

EMSS bridges the gap between electrical, mechanical and electronic engineers with one easy-to-use package. Design engineers analyze the total behavior of a system including the electromagnetic device and the electronic drive controller. Applications include solenoids, transformers, sensors, and a host of other electromechanical devices Noun 1. electromechanical device - a mechanical device that is operated by electricity mechanical device - mechanism consisting of a device that works on mechanical principles .

Ansoft's ability to address this need with EMSS is a significant step in improving circuit simulation accuracy and its value to design engineers." EMSS Product Features Ansoft's EMSS is a significant technology advance in the design and analysis of electromechanical systems. EMSS combines finite element analysis Finite element analysis (FEA) is a computer simulation technique used in engineering analysis. It uses a numerical technique called the finite element method (FEM). There are many finite element software packages, both free and proprietary. (FEA (Finite Element Analysis) A mathematical technique for analyzing stress, which breaks down a physical structure into substructures called "finite elements." The finite elements and their interrelationships are converted into equation form and solved mathematically. ), mechanical dynamics and electronic circuit equations in a comprehensive, easy-to-use software package for electrical and mechanical engineers. EMSS includes a schematic capture schematic capture - The process of entering the logical design of an electronic circuit into a CAE system by creating a schematic representation of components and interconnections. module to drive transient simulations, offering graphical editing of electrical circuit models with automatic node numbering. Magnetic FEA simulations need only be completed once and used for both initial conditions and time domain simulations - saving critical design time. EMSS eliminates the traditional time-stepping process implemented in other packages when attempting to solve the electromagnetic transients problem. The drawback DRAWBACK, com. law. An allowance made by the government to merchants on the reexportation of certain imported goods liable to duties, which, in some cases, consists of the whole; in others, of a part of the duties which had been paid upon the importation. of the time-stepping approach is dealing with long solution times every time a change is made to the mechanical load or the power electronics drive. Hours are lost waiting for results. By solving the electromagnetic fields within the device using highly accurate finite element analysis techniques, EMSS automatically creates an equivalent circuit model of the device and allows system simulations to run within Maxwell SPICE or Analogy's Saber so that changes to the system are calculated in seconds! This rapid response allows the engineer to quickly evaluate alternatives for optimal system performance. The equivalent electrical circuit can be solved in either Maxwell SPICE or exported to Analogy's Saber format. Once the circuit has been defined and solved, the results can be viewed in the signal post processor. EMSS models may be distributed to other Maxwell SPICE and Saber users without disclosing proprietary design information. Suppliers and vendors are able to work closely together without sacrificing design integrity. Additional EMSS Rollout Activities Ansoft will host a series of seminars introducing EMSS technology throughout October and November. There is no fee for the seminars but pre-registration is required.
