Senior Motor Electromagnetic Engineer

Job description

Job responsibilities

• Develop, validate, and maintain electromagnetic models for Zipline’s propulsion and auxiliary motors.
• Build a reusable and well-governed library of motor models, assumptions, material data, winding definitions, simulation results, and validation evidence.
• Generate torque-speed envelopes, efficiency maps, loss breakdowns, voltage and current requirements, flux-linkage and inductance maps, demagnetization limits, and fault-performance data.
• Create scalable design-space “clouds” and perform sensitivity and uncertainty studies across geometry, materials, windings, temperature, tolerances, and operating conditions.
• Develop reduced-order and surrogate models for aircraft optimization, mission simulation, controls development, and thermal analysis.
• Integrate motor models with inverter, battery, propeller or driven-load, thermal, and aircraft mission models.
• Evaluate motor architectures, electromagnetic materials, supplier concepts, and emerging technologies using first-principles analysis, simulation, and test data.
• Optimize designs for efficiency, mass, torque density, thermal performance, acoustic behavior, controllability, reliability, and cost.
