  • Software Review: FEA for Electric Motors
    As an engineer, I must often tailor designs for size, weight, power consumption, and other factors. My employer had been using a general-purpose electromagnetic- simulation package based on FEA techniques. We used the software in making custom permanent-magnet motors, as well as motors for consumer
  • Software Animates And Analyzes Fluid-Power Curcuits
    Until recently, engineers designing fluid-power systems and electrical controls made schematics with high-end CAD packages, lowcapability 2D sketching software, or both. A component list in Automation Studio appears on the left and a library navigator on the right. A user is looking
  • Motion Reference Guide: Software Keeps Linear-Stage Integration Straight
    Design software has progressed to the point where it can take over many aspects of linear-actuator selection and simulation. In the past, machine builders often made their own linear actuators. They typically assembled, programmed, and troubleshot multiple components from different suppliers
  • Simulating for Mechatronics
    that no one company can address this span of tasks alone. The result is better links between mechanical simulation, electrical simulation, and control design software. For example, National Instruments Corp. and recently collaborated to improve mechatronics-oriented design by posting online
  • Modeling optimizes drive systems
    Better modeling and simulation software lets powertrains perform their best. Ecostar Electric Drive Systems L.L.C. Integrated electric powertrains from Ecostar, Dearborn, Mich., can provide 10 to 80 kW of power. The powertrains are being used in an array of next-generation electric
  • Best practices for CFD simulations
    Early design concepts are quickly verified in CFD software such as CFdesign for plausibility and trends. This analysis took only 1 hr to complete using CFdesign's default natural convection settings for steady-state analysis. Feedback from simulations has helped guide placement of heat sources
  • Hybrid CAD for hybrid powertrains
    Simulation software now tackles the complicated interactions that arise when planning modern vehicular drive systems. Views from the Maxwell and RMxprt programs illustrate the kind of electrical components these packages can help optimize. RMxprt is the entry point for the Ansoft automated motor
  • Avoiding meltdown
    Thermal-simulation software can help keep hot mobile devices running cool. It's no secret that the mobile-device market is the primary driver of innovation within the electronics industry. But the small size of modern mobile devices also creates thermal-management challenges. Cramped corners
