John Cockerill, enablers of opportunitiesDriven since 1817 by the entrepreneurial spirit and thirst for innovation of its founder, the John Cockerill Group develops large-scale technological solutions to meet the needs of its time: facilitating access to low carbon energies, enabling sustainable industrial production, preserving natural resources, contributing to greener mobility, enhancing security and installing essential infrastructures.Its offer to businesses, governments and communities consists of services and associated equipment for the sectors of energy, defence, industry, the environment, transports, and infrastructures. With more than 8,000 employees, John Cockerill achieved a turnover of € 1.417 billion in 2024 in 28 countries, on 5 continents.John Cockerill has been providing its expertise to the defense industry for 200 years. Today, John Cockerill Defense offers Cockerill® modular gun turrets from 25 to 120 mm caliber, Arquus® high-mobility vehicles, technical and tactical training on these systems, and Agueris simulators.Your Mission:The goal of this thesis is to develop a prototype of a BLDC (Brushless DC motor) speed controller that complaints to electrical military environment.1. Define the needsYou will do some research on existing open source solutions to define the work path. The design will probably be based on an open-source BLDC speed controller (Figure 1) to makes things easier and to allow the product to have a lot of features in a short period of time.Figure 1: Typical commercial speed controller (Left) and BLDC motor (Right).2. Conceptual designThe electrical constrains on the device should be studied to be able to successfully pass military standard (EMC). A safety mechanism should be implemented in case of defect.3. Create the prototype and test itYou will design a board to control a BLDC motor. Tests will be carried out on the PCB to verify that the design works well and the military standard are successfully passed.Subject discussed:
BLDC motors
Speed controller
EMC
Filtering
Analog sensor
PCB design
Altium Designer
Your Profile:
Student in a master's degree education level in electronic
Minimum level B2 in French and English
Available for at least of 2-3 months
You should be interested in EMC and in PCB design.
The EMC standard are difficult to successfully pass. A support in EMC is a plus.
Your Internal Support:During this internship, you will be supported by the electronic R&D department and the electronic industrialization and prototyping department of John Cockerill Defense. The internal supervisors will be:
Matthieu Close (R&D engineer) - project definition PCB design
Alexandre Copis (R&D engineer) - BLDC support
Maxime Javaux (R&D engineer) - PCB design, BLDC support and EMC support
