The vector control technique controls the two vectors, excitation and torque, of the stator current separately, and then synthesizes and converts them into parametric control signals for the inverter to achieve adequate control of the electromagnetic torque.
The motor runs cool even at low speeds. This highly efficient inverter technology suppresses noise and harmful harmonics that are unavoidable in standard inverters. A new generation of proprietary vector inverter control is used to convert DC to AC for improved resistance to high temperatures, higher conversion efficiencies, energy savings, and improved reliability.
