Master’s in E-Axles and Transmissions for EVs
About our Master’s in E-Axles and Transmissions for EVs
The Master’s in E-Axles and EV Transmissions
is an advanced program designed to train specialists in e-axle, EV transmission, and next-generation electric powertrain. Throughout the master’s program, you will work in depth on the design, sizing, and integration of complete e-axles (electric motor + gearbox + differential + associated electronics), as well as electric transmissions for light vehicles, sports cars, commercial vehicles, and high-performance applications. You will learn to translate vehicle requirements (acceleration, top speed, gradeability, NVH, efficiency, cost) into technical specifications for the e-axle and EV drivetrain, and to make architectural decisions that directly affect the range, performance, and comfort of an electric vehicle.
This Master’s in E-Axles and EV Transmissions combines advanced mechanics, vehicle dynamics, gear engineering, bearings and housings, with electric motor integration, torque control, thermal aspects, NVH, manufacturing, and validation. The focus is on the complete EV transmission: from the definition of the reduction ratio to the industrialization of the e-axle as a platform-ready module. The goal is for you to graduate prepared to work at OEMs, Tier 1 suppliers, R&D centers, or consulting firms as an e-axle, electric transmission, and electric powertrain engineer.

Skills and results
What you will learn
You will understand the complete EV drivetrain ecosystem: electric vehicle architectures (front-wheel drive, rear-wheel drive, e-axles on both axles, dual motor, torque vectoring), differences between centralized systems and integrated e-axles, as well as the impact that the EV transmission has on performance, range, and efficiency. You will learn to compare different electric powertrain configurations and to justify why a certain e-axle scheme is more suitable for a specific market segment or platform type.
You will master the sizing workflow of an e-axle based on vehicle requirements: masses, acceleration targets, top speed, gradeability, wheel torque limits, battery and inverter constraints. You will see how to derive EV transmission ratios, nominal and maximum torques, gear and shaft stresses, as well as overall EV drivetrain efficiency requirements. The Master’s in E-Axles and EV Transmissions will teach you to go from a vehicle target sheet to a coherent technical specification for the e-axle and electric transmission.
You will delve into the mechanical design of e-axles and EV transmissions: spur and helical gears, single- or multi-speed reducers, open and limited-slip differentials, bearings, shafts, and housings. You will learn to evaluate stresses, fatigue life, micro-pitting, flank contact, stiffness, alignments, and tolerances. You will understand how packaging, cost, and durability are balanced in a real EV transmission, and how these decisions are integrated within the e-axle module.
You will understand the interaction between the e-axle, electric motor, and inverter within the electric powertrain. You will study motor efficiency maps, torque curves, thermal limits, and how they combine with the EV transmission to cover the operating range of the electric vehicle. You will learn to analyze the system from the standpoint of overall efficiency (battery-to-wheel), electric noise, and smoothness in torque delivery, ensuring that the EV drivetrain architecture makes sense both for engineering and for business.
You will specialize in NVH (Noise, Vibration & Harshness) and comfort applied to e-axles and EV transmissions. You will study gear excitations, electric motor torque orders, resonances, vibrations in housings and supports, and how these are perceived in the cabin. You will see strategies to reduce gear noise, whine, hums, and vibrations typical of the EV drivetrain, learning to design and tune an electric transmission that combines efficiency with acoustic comfort.
You will develop competencies in lubrication, thermal management, and sealing of e-axles and EV transmissions. You will work on specific oils for the e-axle, circulation and splashing, churning losses, foam generation, venting management, and design of oil circuits within the module. You will analyze how the heat generated by gears, bearings, and the integrated motor is dissipated, and how the overall cooling system of the electric vehicle coordinates with the electric powertrain.

Master’s in E-Axles and Transmissions for EVs
The Master’s in E-Axles and EV Transmissions is aimed at engineers and technicians in mechanical engineering, automotive, industrial, electrical, or related fields who want to specialize in e-axles, EV transmissions, and electric powertrains. It is also ideal for professionals who already work at OEMs, Tier 1 suppliers, or consultancies and wish to make the leap to electric vehicle projects, moving from conventional transmissions to integrated electric transmissions. It is advisable to have a background in machine mechanics, strength of materials, and fundamentals of vehicle dynamics, as well as comfort with spreadsheets and CAD/CAE tools. The ideal profile combines an interest in classical mechanics (gears, bearings, housings) with motivation for the future of the e-axle and the EV drivetrain.
SEIUM designs this program to cover a real gap: generic master’s degrees in electric vehicles are abundant, but very few delve with depth into the mechanical core of the electric powertrain: the e-axle and the EV transmission. The Master’s in E-Axles and EV Transmissions focuses exactly there, combining gear design, structural sizing, NVH, lubrication, thermal management, integration with the electric motor, and validation. The approach is applied: from the first module you will work with real EV drivetrain cases, reduction ratios, torque maps, and range targets. SEIUM’s online format allows you to combine training with professional activity and, at the same time, incorporate projects from your own environment as case studies. The goal is that, upon completion, you will be able to sit in an e-axle meeting and provide criteria on architecture, electric transmission, cost, efficiency, and robustness.
