ABOUT THE INDUSTRY PARTNER
Jorson Technologies offers a unique service where all the R&D is done in house, offering all the required services from concept, design, prototype through to finished product without the need to share your idea or concept with several different companies.
Jorson Technologies work through a highly efficient and well-practiced method of finding the best solution for the task whilst minimizing the costs generally associated with R&D. This is because generally multiple prototypes are modelled and created to analyze the performance of the part. Instead, by using Solidworks in conjunction with 3D printing, Jorson only need to go to the manufacturing stage with your project once.
WHAT’S IN IT FOR YOU?
- Opportunity to work with the CEO and Directors
- Unique design will offer learnings that are not on offer elsewhere
- Working within the factory offers learnings and experience with our other services offered to our clients, including 3D printing technologies, Solidworks software and multiple engineering tools and equipment
- Opportunity for ongoing employment post the initial assignment.
RESEARCH TO BE CONDUCTED
A unique opportunity to work with the team to develop a control system for a unique generator. This will include working with the directors and senior engineer. This will be at Jorson Technologies’ factory in the Whitsundays and working with a highly motivated team that are focused on delivering something exciting that has multiple applications.
Whenever a conducting wire comes in proximity to a magnetic field, an opposing magnetic field is generated in accordance with Lenz’ law. Similarly, a change in magnetic field will induce a voltage across a conducting wire (Faraday’s law). Also, when a conducting wire suddenly is switched OFF, the change in current is delayed by the effect of inductance which generates a spike of voltage in the opposite direction of current flow, creating torque that opposes the motor shaft (Back EMF).
This means that for a typical DC motor, when the conducting wire is in the ON position the current flowing through the wire produces torque on the motor shaft, but a small amount of torque flows backwards primarily due to the geometry of the conducting wires. When the conducting wire is OFF, the rotating magnetic field induces a magnetic field that opposes the direction of the motor shaft.
The prototype motor aims to capture the collapsing Back EMF and recycle its generated voltage such that it produces positive torque on the motor shaft (torque in the same direction as the motor shaft).
SKILLS WISH LIST
If you’re a PhD student and meet some or all the below we want to hear from you. We strongly encourage women, indigenous and disadvantaged candidates to apply:
- A student in the field of Engineering, with experience in electric circuit design and autonomous control/s
- Strong teamwork skillset
- Strong ability to analyse and interpret research output.
To produce an Electric Circuit that effectively operates and controls a Prototype Permanent magnet Direct Current Induction Motor. The motor has an array of permanent magnets and conducting wires which produces a rotating magnetic field with a novel approach, such that the ‘Lugging’ force (illustrated by Lenz Law) is minimised.
The controller needs to be able to detect the relative position of the conducting wires and permanent magnets and send logic signals (ON and OFF) to solid state switches. A solid-state circuit is also required to convert AC to DC and to detect the logical commands then perform the task of switching several components ON and OFF at a period of (≈10-20ms).
Once the design of the electric circuit and basic controller is complete, a more advanced control can then be established. The motor needs to be started ‘softly’ and reach its set speed in a pre-determined amount of time. The speed of the motor needs to be controlled in a closed loop (such that it detects a change in speed and automatically increases/decreases the voltage to maintain a set speed). The motor needs to be able to be operated remotely.
The intern will receive $3,000 per month of the internship, usually in the form of stipend payments.
It is expected that the intern will primarily undertake this research project during regular business hours and maintain contact with their academic mentor throughout the internship either through face-to-face or phone meetings as appropriate.
The intern and their academic mentor will have the opportunity to negotiate the project’s scope, milestones and timeline during the project planning stage.
