Design Process


Our Electric Motor Design & Manufacturing Process

The Parvalux design process consists of 4 key aspects; the overall design process, the software used for this, prototyping, and testing

Utlising these 4 elements enables us to design standard, semi-custom, and fully bespoke products that are ready for manufacture. This is a process that we've been carrying out and developing for 70 years, and it is this that makes us so trusted to power products in a range of different industries, whatever the requirements

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 exacting 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 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. The benefit of these technologies is that a ‘proof of concept’ can be manufactured in literally days and at low cost.




We use high-performance dynamometers and simulate applications using LabView or a range of application specific test-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.
