Electric motor and electromagnetic design engineer (Ph.D.) helping hardware teams go from concept to a validated design, with FEA results you can trust and reports your engineers can act on. For 10+ years I have designed and analysed electric machines and magnetic devices in ANSYS Maxwell (2D/3D) and Motor-CAD for clients in the US and Europe, from early-stage startups to R&D groups. Typical projects: • Permanent-magnet motors: PMSM, BLDC, IPMSM, multiphase and fault-tolerant machines, axial-flux and PCB-stator motors for robots and drones • Induction motors and generators: sizing, equivalent-circuit parameters, efficiency maps • Magnetic gears, couplings, latches, brakes, switchable magnets and limited-angle actuators • Special devices: superconducting (MgB2) and flux-concentrator models, fault current limiters, induction heating, electrostatic and insulation studies • Coupled electromagnetic-thermal analysis (Maxwell + Workbench) and reverse engineering of existing products What you get: • A parametric FEA model you own (Maxwell / Motor-CAD project files) • Torque, back-EMF, cogging and torque ripple, losses, efficiency and saturation results, cross-checked against analytical calculations • Design optimisation for torque density, cost, magnet volume or temperature • A clear technical report with plots, design decisions and next-step recommendations • MATLAB/Simulink models and control strategies (FOC, MTPA, fault-tolerant control) when the drive matters Background: • Ph.D., M.Sc. and B.Sc. in Electrical Engineering, Port Said University (electrical machine design and theory) • Invited researcher at the University of Oviedo, Spain (Erasmus+): electromagnetic design and parameter identification of electrical machines • Co-author of research on the electromagnetic design of fault current limiters for HVDC systems • Instructor of online courses on ANSYS Maxwell, Motor-CAD and PMSM/BLDC simulation • Top Rated on Upwork, 30+ contracts, consistent 5-star client feedback How I work: a short call to fix specs and constraints, then fixed milestones with model, results and report delivered at each one, and revisions until the design is clear. I respond quickly and overlap comfortably with European and US working hours. Have a motor, actuator or magnetic device to design, verify or improve? Send me the specs (or just the problem) and I'll tell you how I would approach it.
