Detailed design solutions using advanced analysis

Electromagnetic design

Detailed electromagnetic modelling underpins the design of Magnomatics technologies and its capability in realising bespoke machines and actuators of all types. Magnomatics employs an extensive suite of advanced Finite Element Analysis software from Vector Fields, including Opera 2D and Opera 3D with Elektra, Tosca and Carmen and rotational and translating motion modules. Its capabilities in both 2d and 3d include:

• Magnetostatics
• Steady-state AC analysis
• Transient and Dynamic (coupled motion) modelling accounting for eddy currents
• Circuit coupled modelling
• Detailed iron loss calculation

Our experienced team of post-doctoral engineers offer comprehensive design, analysis and optimisation of all types of electromagnetic and electromechanical devices, accounting for non-linear materials, motion induced eddy currents, circuit coupling, transient currents, iron losses, non-ideal magnetisation of magnets, saliency and cogging forces, end-effects and end-winding calculations.

Thermal modelling

Thermal modelling is key to the design of all electrical machines whether they are continuously rated or subject to sparse duty-cycle operation. Magnomatics have thermal modelling expertise in all aspects of electrical machine design, from simple C-core actuators to high-speed machines, using 2D and 3D finite-element and lumped-parameter transient models. The thermal performance of a number of electrical machines has been successfully validated using these models, enabling us to confidently design to tighter limits and pass on the resulting mass and volume reductions to our customers
