Analysing component behaviour with time and motion

nduced effects of motion addressed in new design and analysis tool

Ansoft Corporation announces Empulse, a new product addition to the Maxwell EM tool suite. Empulse's revolutionary technology addresses a component's behaviour that varies as a function of time and motion. This new capability is introduced in Maxwell 2D v7.0. Empulse can be used by designers within industries such as automotive, consumer electronics, and industrial automation.

Empulse is available as an upgrade for current Maxwell 2D users or as a stand-alone product.

Historically, software tools have not provided insight into the time-varying behaviour of components.

'With Empulse, Ansoft has once again proven itself to be the industry leader by providing new technology which enables next generation, high performance device design,' said Adrian Perregaux, Director of Marketing, EM Products.

'Our target applications for Empulse include electric machines, frictionless bearings, eddy current brakes, magnetic levitation, and any device where time-varying electromechanical system behaviour is of interest.' Empulse is a time-domain analysis software package that solves coupled non-linear electromagnetic field, circuit, and motion problems using a time-step finite element approach.

This technology addresses the many devices where behaviour changes as a function of time, motion, and the effects induced by motion.

Special features in Empulse include: Freely constrained large motion and motion induced physics * Components can be defined as a function of time, position or speed * User-controlled time step and solution interval * Automatic mesh handling throughout the chosen solution interval * Easy access to time-dependent solution parameters during the simulation * Field solutions are available at user defined times throughout the simulation * Advanced control loop capability
