PyMotorCAD documentation 0.4.3#
Introduction#
Ansys Motor-CAD is a dedicated design and analysis tool for electric motors. It enables rapid and accurate multiphysics design and analysis of electric machines across the full operating spectrum.
Today’s electric motor design requires multiphysics analysis across wide torque and speed operating ranges to accommodate rapid development cycles and system integration. Motor-CAD facilitates this cutting-edge design approach by providing:
Intuitive, template-based setups for fast initial electric machine designs
Built-in electromagnetic, thermal, and mechanical solvers for multiphysics insights
Rapid analysis of efficiency maps, torque and speed characteristics, and drive cycles
Quick evaluation of motor topologies and concepts to produce designs that are optimized for size, performance. and efficiency
What is PyMotorCAD?#
PyMotorCAD is part of the PyAnsys ecosystem that facilitates the use of Motor-CAD within a Python environment in conjunction with other PyAnsys libraries and external Python libraries.
PyMotorCAD uses a Python JSON-RPC (remote procedure call) interface for Motor-CAD to launch or connect with a Motor-CAD instance, either locally or from a remote machine via HTTP.
PyMotorCAD allows you to programmatically create, interact with, and control a Motor-CAD model, with or without using the Motor-CAD GUI. You can achieve Motor-CAD automation by running scripts, either internally via the Motor-CAD Scripting tab or externally.
Features#
Features of PyMotorCAD include:
The ability to launch Motor-CAD instances and connect to already-running instances of Motor-CAD.
The ability to control Motor-CAD by automation using PyMotorCAD API methods to carry out Motor-CAD actions, such as setting and retrieving Motor-CAD parameters. For the list of API methods, see the MotorCAD API.
The ability to automate workflows and methodologies within an instance of Motor-CAD via its internal Scripting tab. For information internal scripting in Motor-CAD see the User guide.
Automation control of Motor-CAD via external scripts. Workflows and methodologies can be carried out with either a visible Motor-CAD GUI or via BlackBox mode. For adding PyMotorCAD to your own Python, see Adding to external python and contributing.
The ability to control communication and couple or link Motor-CAD with other software such as Ansys optiSLang.
The ability to run automated sensitivity analysis studies and/or select tolerance buildup to produce robust designs.
Allowing users to introduce their own formulations into Motor-CAD.
The running of multiple parallel Motor-CAD instances via an external script. Ansys optiSLang can be employed to carry out detailed optimizations by controlling multiple Motor-CAD instances in parallel.
Example scripts for tutorials on Motor-CAD features and abilities.
Customizable example scripts for common or advanced workflows, both within Motor-CAD and involving the coupling of Motor-CAD to other software.
Documentation and issues#
Documentation for the latest stable release of PyMotorCAD is hosted at PyMotorCAD documentation.
In the upper right corner of the documentation’s title bar, there is an option for switching from viewing the documentation for the latest stable release to viewing the documentation for the development version or previously released versions.
You can also view or download the PyMotorCAD cheat sheet. This one-page reference provides syntax rules and commands for using PyMotorCAD.
On the PyMotorCAD Issues page, you can create issues to report bugs and request new features. On the Discussions page on the Ansys Developer portal, you can post questions, share ideas, and get community feedback.
