Title: Di Wu – Innovator in Brushless DC Motor Technology
Introduction
Di Wu is an accomplished inventor based in East Greenwich, Rhode Island, United States. With a strong focus on innovation in electrical engineering, he holds two patents that showcase his expertise in motor technology. His contributions have significantly advanced the field of brushless motors, particularly in applications involving challenging environments.
Latest Patents
Di Wu's most notable invention is a brushless DC motor with a permanent magnet rotor. This innovative motor comprises a permanent magnet rotor rotating coaxially within a stator that contains electric windings, separated by a radial, axially extending gap. The rotor is ingeniously designed using four or more ferrite ceramic magnets that are spaced equidistantly circumferentially around the rotor and extend radially along its length. The use of corrosion-resistant ferrite magnets ensures the motor's durability, especially in wet environments, making it suitable for applications in hot salt water conditions.
The structure of the rotor features bar magnets, which are rectangular in cross-section and extend radially, placed perpendicularly to adjacent magnets. These bar magnets are separated by wedge-shaped or quadrant-shaped sections of magnetic material, optimizing the motor's efficiency. The polarization of the permanent magnets creates a Halbach Array, enhancing the magnetic field's effectiveness. This design results in a highly efficient, effective, and durable motor, particularly ideal for driving wet rotor pumps.
