Title: Innovations of Jian Luo in Brushless DC Motors
Introduction
Jian Luo is an accomplished inventor based in Pasadena, California, known for his contributions to the field of electrical engineering. He holds two patents that showcase his innovative approach to motor design. His work primarily focuses on brushless DC motors, which are essential in various applications due to their efficiency and reliability.
Latest Patents
Jian Luo's latest patents include a "Brushless DC Motor with Stepped Skewed Rotor" and a "Direct Current Torque Motor with Extended Stator Poles." The first patent describes a brushless DC permanent magnet motor featuring a step skewed rotor. This design incorporates a rotor shaft with a uniform cross-sectional configuration defined by N planar sides, where N corresponds to the number of poles in the motor. The rotor is equipped with two annular sets of identically shaped bread loaf magnets, with one set having its orientation reversed compared to the other. This innovative arrangement allows for a predetermined skew angle, enhancing the motor's performance.
The second patent, the "Direct Current Torque Motor with Extended Stator Poles," presents a permanent magnet DC torque motor with a cantilever-mounted stator nested within a cup-shaped rotor. The design includes permanent magnets positioned around the rotor's inner periphery, with a stator core featuring radially outwardly directed webs and coils. This configuration increases the total flux for a given motor volume without requiring additional electrical energization, making it particularly suitable for applications such as engine air throttle actuators.
