"For starters, the electric motor contains three key components: motor, reducer and inverter. The motor generates torque. The reducer transfers that torque to the wheels, whereas the inverter converts the high-voltage battery's direct-current (DC) power to alternating current (AC), precisely controlling how and when that power gets used. Hyundai dove deep into the inverter in its latest explainer, saying it heavily influences power distribution and efficiency."
"But before we dig into the inverter, this is how an EV actually gets moving: DC power from the battery flows into the inverter, where it's converted into AC for the motor. When the AC flows through the motor's coils, it creates a magnetic field that constantly changes thanks to the alternating current, making the magnetized rotor at the center spin. All this happens within milliseconds of when you touch the throttle, delivering that instantaneous response that jolts your head back."
An EV traction system centers on a battery, inverter, motor, and reducer working together to convert stored electrical energy into motion. DC power from the battery is converted to AC by the inverter, which feeds the motor's coils and generates a changing magnetic field that spins a magnetized rotor. The reducer transfers the motor's torque to the wheels. Inverter configuration heavily influences power distribution, efficiency, and throttle response. Increasing battery voltage or motor current can unlock greater performance. Specific inverter and drivetrain tuning enabled high-performance variants such as the Hyundai Ioniq 5 N and the Kia EV6 GT.
