PESC was created in 2021 to provide educational and solution driven expert advice on the design (incl. optimal sizing), control, testing and manufacturing of power systems, in particular for electric machines. Using first principles and physics based approaches, as well as a strong design for manufacturing and cost oriented philosophy, PESC offers consulting services to provide system level solutions to real world problems.

PESC mostly helps small to medium companies to get to the right place with their motors. We're passionate about e-mobility, energy generation and robotics applications, although our services are designed to cater to anyone working with electric motors. Below is a non exhaustive list of services / keywords. 

We're a small and highly flexible structure so it's best to reach out and discuss your needs!

Let's get into our bread and butter!

Modelling / Optimization 

• • We create a numerical twin of your motor and extract torque, power curves, efficiency maps, loss breakdown, equivalent models, fault characteristics...

  • We use this standalone model to investigate your specific issues 

  • We can quickly provide tool safe modifications to improve your motor

  • We quickly can evaluate re-winding and motor length adjustments

  • We provide complete electromagnetic motor / system sizing considering your requirements

  • Our specialty is to optimize motors using our PESTO databases, learn more!

  • We help with magnetic materials selection (electrical steel, permanent magnets, insulations...)

  • Motor topology exploration (inner vs. outer rotor, SPM vs. IPM, NdFeB vs Ferrite,...)

  • We provide the simulation files : 2D/3D FEM, CAD models, calculation sheets...

  • We run micro geometry optimizations to improve e.g. NVH without sacrificing performances

  • We also study NVH, cogging torque, eccentricities, unbalance magnetic pull... issues

  • We perform thermal analysis

  • We can integrate battery (if applicable) and inverter in the loop

Manufacturing / Testing 

• We provide complete motor technical drawings, ready for manufacturing

• 2D prints of stator, rotor, magnets, winding patterns, etc. 

• Includes state of the art quality control call outs

• We also provide CAD files : STEP, DXF...

• We assist with sensors choice (position, temperature...)

• We are expert about motor assembly & manufacturing methods

• Winding termination methods

• We can run dyno characterization (<10kW) and help with test data analysis

• Reliability testing suites

• Design of test procedures and equipment

• We assist with prototyping 

• We help identify manufacturing partners

• We help evaluate CAPEX / OPEX investments

Documentation / Training

• Technical training

• Bespoke documentation & reports

We have experience with all sorts of motor technologies, DC motor, induction motor, reluctance motor (SwitchedRM, SynRM..), PM motor (incl. BLDC, PMSM, IPM, etc.) and radial, axial and transverse topologies, single phase, three phase and more...

PESC's ambition is to contribute in all domains from home appliances / consumer electronics, to traction applications / e-mobility, energy generation industry and robotics.

Here are a couple of examples from our portfolio

e-mobility

• Cost reduction and re-winding of an e-bike powertrain. Validated and pushed to market.

• Improvement of a micro mobility direct motor thanks to tool safe modification and material selection. Validated and pushed to market.

• Complete motor optimization of a new micro mobility direct motor. 

• Motor design consulting for marine application.

Robotics

• Support with global architecture and motor selection for a conveyance AGV bot.

• Motor design consulting for multi-motor system.

Global

• Estimated investment cost of electric motor production line for Tier1 supplier.
