About this project

Induction Motor Speed Controller Project

Objective: Design and implement a system to precisely control the speed of an induction motor using embedded electronics.

Context: Industrial and agricultural sectors in India rely heavily on induction motors, where efficient speed control can save energy and reduce wear, improving operational reliability and cost-effectiveness.

What you'll build: You'll interface an induction motor with an Arduino or PIC microcontroller, using TRIAC/DIAC or IGBT-based controllers for power modulation. PWM techniques and opto-isolators will enable safe, precise speed adjustments, with voltage and current sensors for feedback and overload protection. Embedded programming will handle control logic and safety features.

Deliverables: Functional speed controller prototype, demonstration video, and a report detailing design, testing, and safety validation.

Milestones

Acknowledge your understanding of the project scope and deliverable expectations. Submit a brief statement confirming your commitment to the timeline and requirements outlined in the project brief.

2. Motor interfacing & speed measurement

5 marks 5d

Connect the induction motor to your control hardware and implement a method to measure its rotational speed (e.g., using an optical encoder or tachometer). Submit clear photographs of your setup, a wiring diagram, and a short video demonstrating accurate speed measurement at different motor speeds.

3. Controller circuit design

5 marks 5d

Design and document the complete controller circuit for adjusting the induction motor speed. Submit a detailed schematic (hand-drawn or software-generated), a list of all components with values, and a brief explanation of how your circuit achieves variable speed control.

4. Software logic for speed control

5 marks 5d

Develop and submit the software code that reads the speed sensor and adjusts the motor drive signal to maintain or change speed as required. Include annotated source code and a flowchart or pseudocode showing your control logic. Demonstrate the code running on your hardware with sample input/output data.

5. Safety and overload testing

5 marks 5d

Test your system for safety and overload protection by simulating fault conditions (e.g., blocked rotor, overcurrent). Submit a test plan, photos or videos of the tests, and a summary of results showing your controller responds appropriately to unsafe conditions (e.g., shuts down or limits current).

6. Integration and final testing

15 marks 5d

Integrate all hardware and software components into a working prototype. Submit a comprehensive video demonstration of the system controlling motor speed, handling setpoint changes, and responding to faults. Include a final wiring diagram, code, and a brief report summarizing test results and any issues resolved.

7. Arduino Alcohol Sense Engine Lock

15 marks 5d

Design and implement an Arduino-based alcohol sensor system that disables the motor if alcohol is detected. Submit your circuit diagram, annotated code, and a video demonstration showing the engine lock activating when the sensor detects alcohol and allowing operation when clear.
