Motors in real production vehicles
A tour of the motor choices behind well-known EVs.
You'll learn
- Explain motors in real production vehicles at engineering level
- Read the numbers that define the behaviour
- Apply the idea to a real drive unit
Overview
Looking at what real manufacturers actually chose — and why — turns the theory of the last five modules into concrete engineering decisions.
In depth
| Vehicle | Motor type | Notable detail |
|---|---|---|
| Tesla Model 3 (rear) | PMSM (IPM) | Switched from induction to PMSM for efficiency gains |
| Tesla Model S/X (early, front) | Induction | Chosen partly for zero-drag freewheeling in dual-motor layout |
| Nissan Leaf | PMSM | One of the earliest mass-production EV traction motors |
| Hyundai/Kia E-GMP | PMSM, 800V architecture | High switching frequency SiC inverter |
| Formula E race cars | PMSM / axial flux variants | Extreme power density under strict mass and volume limits |
Key takeaways
Remember this
- Real manufacturers make different motor choices for genuinely different engineering reasons.
- Efficiency, packaging, cost and supply chain all weigh into the final decision.
- Even a single manufacturer's choice can shift over time as technology and costs change.
