Need help in modelling gearless wheel for a Venus rover using AC induction

[Anwesh]

I am a 15-year-old student studying physics. I am trying to model the electromagnetic and thermal parameters of a gearless rover wheel for Venus using AC induction. I have labeled this [B/I] because I understand basic electrical circuits and magnetic fields, but I need help understanding the math behind Eddy currents and high-temperature material constraints

One critical parameter will be Curie temperature.

What is the temperature on the surface of Venus, 470°C ?

What is the source of the energy to drive the wheels?
How will you keep magnetic dust out of the mechanism?

What semiconductors are available to control power at high temperatures?
SiC will not do, GaN is a possibility. Look for ultra-wide-bandgap materials.

It would surprise me if any cooling mechanism could be arranged for the drive motors.
Maybe you should use a ceramic structure hydraulic drive, with a molten metal as the fluid. What motor structure could pump the conductive metal hydraulic fluid, MHD ?

Thank you so much for this incredible feedback! It is exactly the kind of deep engineering reply I was hoping to find.
Based on your points regarding the Curie temperature, core materials, and heat management, I have started building a basic 3D assembly model on my phone to visualize the mechanical integration. I’ve attached the screenshots below.
Color-Coded Breakdown of my Current Layout:
• Red: The outer wheel rim providing structural integrity.
• Blue: The load-bearing rotational surfaces.
• Black: The core electromagnetic actuator assembly (relying strictly on electromagnets to avoid the permanent magnet Curie temperature threshold at 460°C).
• Green: A central conical heat-dissipation funnel designed to encourage convective cooling across the dense atmosphere and shed abrasive dust away from the stator-rotor air gap.
My Plan for the Next Design Iteration:
1. Core Laminations: To mitigate the Eddy currents and core losses you mentioned, I plan to split the solid black core design into a laminated assembly utilizing thin, insulated sheets of silicon steel or iron.
2. High-Temperature Material Selection: I am looking into ceramic-coated copper or nickel-clad conductors for the induction coils to manage the 460°C environmental baseline plus the I²R resistance heating.
3. Solid Lubrication: Since standard bearing grease fails instantly on Venus, I'm researching solid-film coatings (like graphite/molybdenum disulfide) or fully ceramic tracks for the blue bearing surfaces.
Would love to hear your thoughts on this assembly layout and the feasibility of managing the stator-rotor air gap clearance under high thermal expansion!

Update V2: I realized a flaw in my initial assembly routing regarding coil rotation. I have updated the 3D model to fix this. The primary induction coil assembly is now completely locked to one of the bearings, while the secondary receiving loops are integrated into the funnel shaped structure.This completely isolates the main power lines from rotational wear and seals the internal wiring matrix against the environment.
