How Hyundai's 2-stage motor system delivers instant EV thrust

Hyundai has released a detailed explainer on how its electric motors work and why the brand’s EVs accelerate with such confidence. At the core of the drivetrain sit three elements: the motor itself, a reduction gear, and an inverter. The inverter converts the battery’s direct current into alternating current, creating a rotating magnetic field in the stator. That field spins the rotor almost the instant you press the pedal — a simple chain of events that makes the response feel effortless.

What’s more compelling are the settings that lift output without a big weight penalty. Hyundai notes that power can be increased by raising voltage or current, but that approach makes the system heavier and cooling more difficult. Instead, the company chose a different path and developed the 2-Stage Motor System — a neat solution that favors usable pace over spec-sheet bravado.

The inverter carries twice the number of power switches: twelve instead of six. In everyday driving, only the first six are active. When the driver floors the accelerator, all twelve come into play, lifting voltage by roughly 70 percent. That’s where the sudden surge comes from, the trait that stands out in the Ioniq 5 N and Kia EV6 GT.

Crucially, the system barely adds mass: nine power-electronics modules were consolidated into three, making the inverter more compact — the kind of packaging win you notice not on paper, but in how cleanly the car delivers its punch.
