4 Design and Prototyping of a Microcontroller-Based Motor Driver Board PFE

Project Overview

• Design and development of a PCB integrating a microcontroller-based control unit, a regulated power supply, and a DC motor driver stage.
• System goals: ensure stable power distribution, enable precise control of motor speed and direction, and provide input/output interfaces for monitoring and command.
• Location: Tunis. Duration: 6 months. Remunerated position.

Scope & Objectives

• Full project lifecycle: schematic design, PCB layout, component selection, prototype assembly, and functional testing to validate performance and reliability.
• Ensure compliance with design specifications and electrical constraints for power electronics and motor control.
• Implement interfaces for monitoring (measurements/feedback) and command (control signals, communication with microcontroller).

Tasks & Activities

• Design power electronics including regulated power supply and DC motor driver stage; simulate critical parts (e.g., using LTSpice) and verify thermal/electrical behaviour.
• Develop microcontroller firmware for motor control (speed/direction), implement control algorithms and I/O handling (Embedded-C preferred).
• Perform PCB layout using Altium Designer, select components, assemble prototype, and run functional and reliability tests on the assembled board.

Required Skills & Tools

• Electronics: power electronics, analog/digital electronics, PCB design and component selection experience.
• Software/Tools: Altium Designer, LTSpice; firmware experience in Embedded-C is preferred.
• Practical skills: prototyping, soldering/assembly, measurement and debugging of motor drivers and power supplies.

Deliverables & Validation

• Completed PCB design files (schematics and Gerbers), assembled prototype board, and documented bill of materials.
• Firmware source code and documentation for motor control; test reports demonstrating performance, stability, and compliance with specifications.
