Antares Senior Motor-Generator Engineer responsible for the design and development of high-speed motor-generator units for Antares nuclear reactors. Serve as the primary technical interface with electric-machine suppliers and lead integration with power conversion systems.

Responsibilities

As a Senior Motor-Generator Engineer, you will own the design and development of high-speed motor-generator units (MGUs) for Antares nuclear reactors.
The ideal candidate has experience designing electric motors or generators, with strong knowledge of electromagnetic design, materials, manufacturing processes, and hardware testing. You can make sound engineering tradeoffs between electrical performance, mechanical integrity, thermal limits, reliability, manufacturability, cost, and schedule.
Roles & Responsibilities:
Own the technical development of high-speed motor-generator units from design through qualification and production.
Serve as the primary technical interface with electric-machine suppliers, reviewing designs, analyses, manufacturing processes, and test results.
Develop motor-generator requirements, specifications, interfaces, and verification plans.
Perform electromagnetic design and analysis of electric machines, including machine sizing, winding configurations, magnetic circuits, losses, efficiency, and operating limits.
Design stator and rotor components, including laminations, windings, insulation systems, permanent magnets, magnet retention, and cooling features.
Lead MGU development and qualification testing, including test planning, execution, data analysis, and resolution of issues identified during testing.
Work with turbomachinery engineers to integrate motor-generator components into high-speed rotating assemblies, including shaft interfaces, rotor structural integrity, and rotordynamics.
Work with electrical engineers to define motor-generator electrical characteristics, inverter interfaces, operating limits, and test requirements.
Develop internal electric-machine design methods, analysis tools, and manufacturing capabilities to support future in-house development.

Qualification

Experience designing stator laminations

Required

Bachelor's degree in Electrical Engineering, Mechanical Engineering, or a related engineering discipline.
5+ years of professional experience designing and developing electric motors, generators, or similar electric machines.
Experience performing electromagnetic design and analysis of electric machines, including magnetic circuits, winding configurations, torque production, voltage characteristics, and losses.
Experience with electromagnetic analysis tools such as ANSYS Maxwell, Motor-CAD, JMAG, or equivalent.
Working knowledge of electric-machine materials and manufacturing processes, including electrical steel laminations, windings, insulation systems, and permanent magnets.
Experience developing electric-machine hardware through manufacturing, assembly, and testing.
Experience making engineering tradeoffs involving performance, reliability, manufacturability, cost, and schedule.
Demonstrated ability to communicate technical information clearly.

Preferred

Master's degree or PhD in Electrical Engineering, Mechanical Engineering, or a related discipline.
7+ years of professional experience designing high-power or high-speed electric motors or generators.
Experience designing permanent-magnet synchronous machines and high-speed motor-generator units.
Experience designing stator laminations, winding configurations, insulation systems, and cooling architectures.
Experience designing high-speed permanent-magnet rotors, including magnet selection, retention sleeves, rotor structural analysis, and shaft interfaces.
Knowledge of electric-machine loss mechanisms, including core losses, eddy-current losses, windage, harmonics, and rotor heating.
Experience with electric-machine thermal analysis and cooling system design.
Working knowledge of inverter-fed electric machines and the effects of inverter operation on machine performance, heating, and reliability.
