Performance Metrics
Critical performance data, such as torque versus speed, power loss, flux in the air gap, power factor and efficiency can be quickly calculated. Output waveforms include:
- Current
- Cogging torque
- Flux in the air gap
Convenient Modeling & Editing Features

Design Sheet Output
Design sheets list all the relevant input parameters and calculated parameters and graphically display waveforms including current, voltage, torque and back EMF as well as a detailed winding layout. RMxprt also can output Excel-format design sheets based on the user-defined template.
Powerful Scripting
RMxprt can be integrated with third party development programs through scripting languages such as VB script, IronPython, Tcl/TK, JavaScript™, Perl™, Excel and MATLAB®. This allows you to customize the design flow and leverage internally developed programs and historical data.
Auto-Design
RMxprt includes convenient features that can guide your design process by automatically determining slot size, coil turns and wire diameter, starting capacitance, and winding arrangement from your given design parameters.
Model Pre-Processor for Electromagnetic Analysis
In addition to providing classical motor performance calculations, RMxprt can automatically generate a complete transfer of the 3-D or 2-D geometry, motion and mechanical setup, material properties, core loss, winding and source setup including the drive circuit directly to Maxwell for detailed finite element analysis calculations. Users avoid the need to import or create geometry and the duplication of effort in problem set-up.
RMxprt can generate the complete ANSYS Maxwell project setup saving users a tremendous amount of time.
High-FIdelity System Models
RMxprt creates high-fidelity, nonlinear equivalent circuits models accounting for machines' physical dimensions, winding characteristics and nonlinear material properties. Engineers can use the resulting equivalent model to explore electronic control topologies, loads, and interactions with drive-system and multi-domain components in ANSYS Simplorer.
RMxprt is the entry point for a comprehensive electrical machine design flow.
