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 needs
You 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 design
The 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 it
You 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
What we offer you:
- Immersion in a stimulating, technology-driven environment
- Concrete and rewarding responsibilities
- A caring and passionate team
We look forward to receiving your application and meeting you.
