Our Partnership with Romax Technology

The easy import from Motor-CAD to Romax tools helps engineers apply time-series radial force and torque-ripple data from motor simulations into driveline models to correctly take into account the effects of electromagnetic forces.

How Motor-CAD Interfaces with the Romax Nexus Simulation Platform

 

Romax Nexus & Motor-CAD

Romax Nexus is the most complete simulation platform for engineering the next generation of electro-mechanical drive systems. It’s cloud-enabled ecosystem of applications align with your drivetrain and transmission development cycle, from rapid modelling and concept exploration to detailed simulation and virtual product sign-off. Intelligently integrated into the wider CAE world, Romax Nexus empowers your teams and enables Right First Time designs.

The three packages within the Romax Nexus platform that interface with Motor-CAD are:

  • Romax Concept
  • Romax Spectrum
  • Romax Evolve

Romax Concept

Romax Concept is a rapid and intuitive early design tool for confident exploration of drivetrain ideas.

2D and 3D design and sizing is seamlessly combined with CAE simulation in an intuitive user interface to help drivetrain designers explore innovative solutions and make confident engineering decisions at the early stages of product development. Designs can be easily taken from Romax Concept and converted into CAD models and drawings, optimised multibody dynamic models and used in any other Romax Nexus product for more detailed analysis.

Romax Concept is able to import a native Motor-CAD file, allowing users to include electric machines created in Motor-CAD in a complete model of a powertrain system inside Concept. This enables a streamlined work flow for evaluating alternative e-powertrain architectures, bearing selection, early NVH assessment, materials costing and transitioning to detailed design and analysis in other Romax products and third-party CAD/CAE tools.


Romax Spectrum

Romax Spectrum provides a complete, validated solution for NVH simulation of electro-mechanical powertrain.

Providing fast, accurate frequency domain analysis for engineering insight and optimisation, Romax Spectrum combines validated analysis methods to predict dynamic gear excitations, with integrated links to electro-magnetic software to import and process motor forces. The powertrain NVH performance can be evaluated using frequency-domain simulation of system vibration response, or an embedded acoustic solver can be used to predict radiated noise and verify design targets.

The interface between Motor-CAD and Romax Spectrum allows the user to import a definition of the electrical machine active geometry (stator and rotor), as well as importing excitation data (tooth forces and torque ripple) required for NVH analysis. A single data file is used for this interface, minimising the amount of data handing, and reducing the risk of user error.


Romax Evolve

Romax Evolve is a multi-fidelity, application-specific tool for the structural design and analysis of electrical machines.

Romax have a proven track record in electro-mechanical simulation and design, rotor dynamic simulation for industrial generators and electrical machine NVH development. Romax Evolve incorporates this expertise into application specific tools for the structural design and analysis of electrical machines, which integrate into powerful multi-fidelity full system analysis. Romax Evolve includes capabilities for durability and efficiency analysis of bearings in electrical machines, rotor-dynamic analysis of rotor shafts, as well as NVH and acoustic analysis of electro-mechanical excitations.

Romax Evolve features the same interface capabilities as Romax Spectrum, whereby the user can import the definition of the electrical machine active geometry (stator and rotor), and excitation data for NVH analysis, within a single data file. In addition, Romax Evolve is able to import a complete electrical machine geometry (including active and structural parts) from a native Motor-CAD file, enabling a streamlined workflow from machine electrical design through to structural and dynamic simulation.
