Design Process


Electric Motor Design and Manufacturing Process

The Parvalux electric motor design and manufacturing process consists of four key aspects; the overall design process, the software used for this, prototyping and testing.

Utilising these four elements enables us to design standard, semi-custom and fully customised, bespoke products that are ready for manufacture. We have been developing our electric motor design process for over 70 years and it’s one of the reasons we’re proud to be considered a trusted provider of drive products, in a range of industries, worldwide.

Find out more about each element of our design process below.

Design process management

Our design process uses a process modelled on Advanced Product Quality Planning (APQP) principles using FEA (Finite Element Analysis). Our core focus is to work as an extension to our customer’s design capability from the outset. This means developing geared motor concepts for volume applications that meet exact technical and commercial specifications. We contribute at every design level, from initial design sketches and 3D-concept models, through to rapid prototypes for ‘proof of concept’.         




We utilise leading electric motor design software tools such as SolidWorks for 3D modelling and Finite Element Analysis (FEA), DonTyne and MathCAD modelling software. These software tools are used to virtually model the various components within the geared motor before we expend cost and time manufacturing. Such software tools can model the performance, both statically and dynamically, to an extremely high level of accuracy. We can therefore provide estimated performance data very early in the design process.





Proof of concept can be manufactured in literally days and at low cost using various additive processes such as selective laser sintering (SLS). Once the software models are complete, we produce rapid prototypes (RP) using various additive processes such as selective laser sintering (SLS), fused deposition modelling (FDM), stereolithography, as well as rapid casting technologies.





We use high-performance dynamometers and simulate applications using LabView or a range of application specific electric motor testing equipment. Using National Instruments software, we can provide SPC analysis on all test data to model and test the ultimate life of the product. Apart from the usual performance criteria such as torque, speed, power, etc., we can test for strength, fatigue, noise (acoustic and electrical), vibration and full EMC and environmental test facilities with our partner company, TRaC.
