Latest Patents

Among Ping Li's groundbreaking inventions is his latest patent that revolves around an electric motor, generator, and commutator system. This patent details a direct current (DC) electric motor assembly featuring a closed-type overlap stator winding, which is commutated via a precisely timed sequence. This innovative approach is capable of generating a stator rotating magnetic field effectively. The coil overlap in the winding and the timed commutation ensures that the current in each stator slot is additive. When a magnetic pole collapses according to the commutation sequence, the energy from the collapsing magnetic field is captured, enhancing the subsequent magnetic field in the sequence. This mechanism allows for the electrical currents from the collapsing fields to flow to low electric potential, thereby adding or subtracting to the DC current supplied by the commutator. Ultimately, this assembly enables the creation of a brushless, high-torque speed-controlled Real Direct Current (RDC) motor, which operates with greater efficiency and power density.
