Electromagnet design for resonant magnetic actuation system
In this project, the loss power of an electromagnet should be studied and optimized using FEM simulation. A prototype of the electromagnet should be constructed.
Keywords: - Magnetic Actuation System
- Electromagnet
Magnetic actuation systems can be used to steer surgical instruments such as endoscopes or catheters by generating a force and torque on hard or soft magnets embedded in such devices. Oscillating and rotational magnetic fields can be used to trigger chemical reactions or locomote magnetic microswimmers.
For such applications, the magnetic field frequencies are in the range of hundreds of Hz up to several kHz. At increased frequencies, both copper losses and core losses increase in the electromagnet.
The project involves the following **tasks**:
- Simulate different losses in the electromagnet using FEA with Comsol for different wire types / arrangements as well as different core materials.
- Compute magnetic fields / magnetic fields gradients that can be achieved with simulated electromagnets.
- Construct protoypes of the simulated electromagnets and verify the FEA results experimentally.
The following **skills / experience** can be useful for the projects:
- FEM Simulations using Comsol Multiphysics
- Programming / Scripting in Matlab or Python
- Mechanical prototyping / workshop skills for building the electromagnet prototypes.
