Latest Patents

Weijie Tian holds a patent for a "Control method for semi-centralized open winding multi-motor drive system." This patent outlines a comprehensive control method that begins with measuring current, voltage, and position signals. The system computes thrust through a velocity loop and distributes it to each motor. It converts thrust into q-axis current and calculates the required dq-axis voltages for each motor via a current loop. The voltage demand is then transformed into the abc coordinate system through coordinate transformation. The method includes modulating the voltage of each motor into a duty ratio instruction, assessing whether the motor is in an over-modulated operating area, and performing necessary over-modulation processing. This innovative control method reduces hardware costs while improving the overall safety and reliability of the system.
