This internship is a part of a 10-week full-time summer internship program opportunity. This role will be based at Archer’s headquarters in San Jose, California and relocation or housing will not be provided. Archer is seeking a motivated and detail-oriented intern to join our motor control and simulation team. This internship provides a hands-on opportunity to gain practical experience in the design, control, and validation of the core components of our aircraft's electric powertrain. You will play a crucial role in the development cycle, contributing directly to the high-performance motor system and power converters that make electric flight possible and pushing the boundaries of aerospace technology.
Job Responsibility:
Develop and refine motor control algorithms in MATLAB/Simulink or PLECS to optimize the performance, efficiency, and thermal characteristics of our high-power-density motors
Create and analyze simulation models of high-voltage DC/DC converters and motor inverters to predict their behavior, stability, and efficiency under various flight conditions
Assist in the electromagnetic and thermal analysis of electric motors using Finite Element Analysis (FEA) software, contributing to the analysis of torque ripple, cogging torque, and loss mechanisms
Contribute to motor design trade studies, evaluating the impact of different topologies, materials, and winding configurations on performance metrics like power density and efficiency
Support the assembly, bring-up, and testing of prototype motor drive and power electronics hardware in the lab, gaining hands-on experience with high-power systems
Develop test scripts and analyze experimental data from dynamometer and bench tests to validate simulation models and characterize component performance
Correlate motor simulation models with experimental data from dynamometer testing to improve model accuracy and validate design choices
Document your simulation results, test procedures, and design analysis in detailed reports and present your findings to the team to inform critical design decisions
Requirements:
Pursuing a Bachelor's (3rd or 4th year), Master's, or PhD in Electrical Engineering or a related field
Strong fundamentals and coursework in Power Electronics, electric machine theory (including electromagnetic principles and motor topologies like IPM/SPM), and control systems
Simulation experience with PLECS and/or MATLAB/Simulink for modeling and simulating motor control systems or power converters
Exposure to Finite Element Analysis (FEA) software such as ANSYS Maxwell, FEMM, or a similar package for electromagnetic simulation
Hands-on experience with lab equipment such as oscilloscopes, power supplies, and electronic loads for testing power electronics
Familiarity with motor control techniques such as Field-Oriented Control (FOC) and Space Vector Modulation (SVM)
Excellent problem-solving skills, a strong theoretical foundation, and a desire to learn in a fast-paced, collaborative environment
Nice to have:
Experience with scripting (Python/MATLAB for data analysis), embedded C/C++
