Abstract

Project S.P.E.E.D. is an energy recovering system. It will be designed to harvest otherwise wasted energy from traffic entering and exiting a revolving door. The motivation for this project is to reduce the costs and demand for electric energy.

The goal for Project S.P.E.E.D. is to show whether or not this design has potential for real world application. This project introduces mechanical and electrical challenges. This involves constructing a door assembly, selecting gear ratios, installing a DC generator and building an electrical circuit. Integrating and optimizing these systems together will produce the maximum energy output with minimal input.

In order to prove whether or not this design will work, a scale model of a working prototype will be presented. 

Introduction

The goal of project S.P.E.E.D. is to scavenge and store energy for later use. Learning objectives include analysis of the system and potential components to determine maximum output. Major tasks are building the revolving door model, selecting an appropriate generator, design of the wiring schematic and testing and recording power output. One of the biggest technical challenges of the project will be choosing the best gear ratio of the door and generator for maximum power output. The desired outcome is to show whether or not this design has potential for real world applications.

1         Deliverables

The project will deliver a scale model of a revolving door connected and geared to a generator which will power a light assembly and charge a battery. The project will also deliver a wiring schematic of the electrical components.

2         Technical Activities

2.1       Door Construction

Design and build a revolving door model. This will give us the dimensions needed for selection of the gear components for a proper gear ratio.

2.2        Gear and Motor Assembly

Select/create input and output gears to connect door spindle to generator rotor. Choose a generator with appropriate specifications. Assemble mechanical components and test for smooth mechanical operation.

2.3       Electrical Component Assembly

Design wiring schematic. Choose appropriate wiring, battery and low electric energy consumption LED light. Assemble electrical components.

2.4       Integration of components

Integrate the electrical components, mechanical components and door model. Test for proper operation and power output.
