Latest Patents

Dong Yu holds a patent for a "Permanent magnet synchronous motor parameter measurement method." This method involves performing maximum torque per ampere and vector control on a permanent magnet synchronous motor, ensuring stable and normal operation. During this stable operation, the method captures α-axis and β-axis currents through three-phase current sampling, which undergoes a transformation from three-phase to two-phase. Additionally, it measures the rotor position angle and electrical rotational speed using a sensor. The six physical quantities obtained are then processed using a recursive least squares method to derive four key parameters: stator resistance, d-axis inductance, q-axis inductance, and flux linkage. This patent highlights his expertise and innovative thinking in motor technology.
