Are you using PSIM v2025.0 or earlier and face this strange torque ripple effect from the Flux or FluxMotor model? This is attributed to the fact that the .mat file contains a non zero initial angle. The .mat uses the mechanical rotor angle and you can be found the rotor angle if you open it. However, PSIM v2025 or earlier…
This article discusses how to simulate a delta-connected PMSM in PSIM, but first let me explain some differences of these two topologies. In a star (Y) connection, each phase winding is connected between a line terminal and a common neutral point. As a result, the phase voltage is lower than the line voltage by a factor of…
The variable editor in Flow Simulator (FS) is an easy yet powerful way to change many inputs quickly. If many model inputs use the same number (a hole diameter for example), consider using a variable to parameterize the input. Variables can be simple numeric input or an equation that can calculate an input based on other…
https://us.v-cdn.net/6038102/uploads/YENM59AEB4C5/ai-tutorial-pdf.pdf 🧭 Overview As electrification accelerates, the need for fast, accurate, and scalable electric motor design becomes critical. Traditional modeling methods like Finite Element Analysis (FEA), while accurate, are time-consuming and computationally…
Fast Track eDrive Efficiency Maps in PSIM This webinar walks through an end-to-end process for generating efficiency maps in PSIM - both at the inverter level and system level - by leveraging its seamless connection with Altair Flux. We'll also cover strategies and tips for making sure all operating points are hit…
This article explores how to automate LTspice using HyperStudy. The first step is to configure the LTspice solver within HyperStudy. LTspice solver set up In order to set up the LTspice solver you have to follow the following steps: Unzip the attached ltspice.zip file to the following directory C:\Program…
This is a webinar recording from June 12th, 2025. This webinar describes the workflow going from Revit Geometry exporting to STEP and then importing to Inspire/SimSolid. https://youtu.be/IhC2LJsMWwQ?si=fLGQ956HZj_N6MTJ
Do you know about the component library in CADFEKO? This continuously growing library contains three types of components: Fully parameterized antenna models (for arbitrary frequency bands) Antenna configurations for special applications (in special frequency bands) Typical platform models for antenna placement analysis The…
📌 Introduction Accurately predicting the performance of induction machines across varying operational conditions is essential for robust electric drive design—especially in automotive and industrial applications. However, full Finite Element Analysis (FEA) simulations, while accurate, can be extremely time-consuming and…
In this tutorial, we walk you through how to define the motor duty cycle and apply temperature limits for generating the efficiency map of a Permanent Magnet Synchronous Machine (PMSM) using Altair FluxMotor.You’ll learn how to set up realistic operating conditions to get accurate and meaningful efficiency results across…
