Motor position feedback signals continuously sampled to execute high-speed vector control algorithm, generating PWM gate drive signals for IGBT inverter stage. Inverter outputs variable-frequency three-phase sinusoidal power to drive AKM low-voltage synchronous servo motors, integrated regenerative braking circuit dissipates deceleration feedback energy to maintain stable DC bus voltage.
