REVR-lutionising the car industry: RMIT student crowned national James Dyson Award winner with electric vehicle retrofit solution13 September 2023
The two most common motors are radial motors and axial flux motors. Radial motors are the most common types of motor found in electric cars and are comprised of a shaft inside of a cylinder that rotates, generating angular momentum. The flux is generated perpendicular to the axis of rotation. Axial flux motors are flat and round, usually made up of discs that spin next to each other. The flux is generated parallel to the axis of rotation. Axial flux motors provide significantly more torque than radial motors but are traditionally harder to make.
REVR uses a unique axial flux motor, where the spinning part (rotor) of the axial flux REVR motor is placed between the disc brakes that exist in nearly all vehicles. The stationary part of the motor (stator) fixes to existing mounting points on the brake hub. As the disc brake is designed to resist high rotating force, it is perfect for mounting a motor. The battery pack is installed in the spare wheel well of the vehicle. A simple sensor detects the position of the accelerator pedal for acceleration and braking.
The Runners Up
Linko, Invented by Keagan Howell
Problem: This invention seeks to tackle two key problems: plastic pollution and the shortage of housing solutions in developing countries. Plastic pollution is a global problem, with humans currently producing more than 350 million metric tons of plastic waste per year. Separately, people all over the world live in poverty, particularly in developing countries where support and resources can be scarce.
Solution: Linko is a masonry construction system that eliminates the need for mortar to secure bricks into position. It uses a plastic insert, crafted form recycled plastic waste material, to establish connections and interlock the layers of masonry bricks. This simple innovation demands minimal expertise and can be effortlessly assembled and disabled, as well as allowing for the reuse and adaptation of both the links and masonry bricks. It addresses two challenges: reducing plastic waste by recycling plastic material and helping to alleviate the shortage of housing solutions in developing nations by providing a straightforward construction system.
Coconut Circular Economy, Invented by Dawei Cao
Problem: Around 931 million tonnes of food goes to waste each year, with 39% coming from food service or retail. Running a coconut coffee speciality stall at Queen Victoria Market in Melbourne, Dawei noticed the coconut waste he was generating. This served as an inspiration to investigate a process of turning food waste into customisable cups.
Solution: The Coconut Circular Economy is a unique circular economy concept that can be applied to different businesses. The concept evolves around the processing the waste that the business generates upfront while producing new products that can then be sold. The coconut waste is processed into coconut waste filament, which can then be used create cups or other usable products.
