Tools to Optimize Efficiencies and Reduce Downtime

Electric Drivetrains: Altair® FluxMotor® 致力于电动旋转机械的仿真驱动设计. It enables users to build from standard or customized parts, add windings and change materials to quickly develop a concept design. Flux models even the most complex electromechanical systems with proven accuracy. It provides multiphysic capabilities – magneto static, steady-state, and transient conditions, 连同电气和热性能-优化机器性能, efficiency, dimensions, cost, and weight.

Reduce Downtime and Extend Useful Life: Asset management with the Internet of Things (IoT) has given birth to "digital twins" of critical assets. Digital twins help organizations optimize product performance, gain visibility into the in-service life of a product, know when and where to perform predictive maintenance, and how to extend a product’s remaining useful life (RUL).
