Electromagnetic IC · Autocar Torque Plate Calculator

Real physics for the CRI-ONE electromagnetic torque-plate propulsion platform (Autocar SKU + electromagnetic-IC family). Ports physics_calculator.py verbatim: 10 first-principles formulas for resistance, inductance, flux density, copper & core losses, IGBT losses, weight, and efficiency. Emits detailed_electromagnetic_design.json + a parametrized can_defs.py for downstream ECU work.

A. Torque Plate Calculator

Defaults are the validated calculate_torque_plate_properties() scenario from the reference module (150×150×20 mm plate, 500 turns AWG12, 300 A, 80 °C, 1 kHz, 400 V DC bus).

IGBT duty cycle (0..1) Silicon-steel core, μ_r=4000. Copper coil, ρ_20°=1.68×10⁻⁸ Ω·m, α=0.00393/°C. Lamination 0.35 mm. Values are per-plate; multiply by plate count for system totals.

B. Autocar Handoff Bundle

Downloadable files driven by the inputs above. Drop into your vehicle firmware repo (CAN definitions match the reference in software/can_defs.py; JSON schema matches blueprints/engineering/detailed_electromagnetic_design.json).

Handoff parameters

Design ID Filenames stay canonical (detailed_electromagnetic_design.json, can_defs.py) so your existing tooling picks them up; the Design ID is written into the JSON design_id field and the CAN module docstring.

🔒 detailed_electromagnetic_design.json unlocks after purchase 🔒 can_defs.py unlocks after purchase 💳 Unlock — $299.00 Larger engagement? Contact →

Downloads are locked. The calculator outputs are public; the engineering JSON and can_defs.py unlock for $299.00 via Stripe. Purchase auto-grants the emic:nda key, signs you in, and emails the mutual NDA to countersign.

Once unlocked, how to use:

Save both files into your Autocar/ECU repo (mirrors the reference paths under blueprints/engineering/ and software/).
Generate ECU code from can_defs.py, wire the JSON into your simulator or PCB placement flow.
The JSON computed block echoes the R/L/B/losses/η values shown above; keep it for design review.

C. Enterprise Pricing — Autocar Electromagnetic IC

Autocar Electronic Automotive Platform · Magento SKU 01-autocar-electronic-automotive-platform.html, list \$3,000,000,000.

The Electromagnetic IC family (10,000+ configurations across four strands, one die) sits above this SKU as a broader integration. Priced under NDA

Every enterprise engagement settles by wire after a signed purchase order — USA companies only, export-control clean. Under NDA we walk through the physics_calculator constants, the full loss model, and the tape-out path with your own operating point.
