Advanced BLDC Motor-Based Regenerative Energy System – Smart Power Recovery Project Kit

Description

⚙️ Project Overview

The BLDC Motor-Based Regenerative System is an innovative engineering project that focuses on energy recovery and reusability from rotating systems.
In conventional motor setups, energy is wasted as heat during braking or slowdown. This system captures that otherwise lost kinetic energy and converts it into usable electrical power to charge a battery or reuse within the circuit.

This regenerative braking concept is widely used in electric vehicles (EVs), hybrid cars, elevators, and wind turbines — and this prototype gives students practical insight into how regenerative systems work using BLDC motors and power electronics.

🔋 Working Principle

The project uses a Brushless DC (BLDC) motor as both a motor and a generator depending on operating mode.

1. Motor Mode:
   When powered, the BLDC motor runs the load normally. A power control circuit drives the motor through MOSFET-based switching or ESC (Electronic Speed Controller).

2. Regenerative Mode:
   When the motor slows down or is externally driven (like deceleration), it acts as a generator.
   The generated electrical energy is rectified using a diode bridge and then directed to charge a battery or feed back to a capacitor bank.

3. Energy Storage & Monitoring:
   The recovered energy is displayed on an LED or LCD monitor, showing how regenerative systems can extend battery life and reduce power wastage.

This demonstrates the core principle behind regenerative braking and smart energy feedback.
