Title: Xuejuan Kong: Innovator in Motor Control Technologies

Introduction

Xuejuan Kong is a prominent inventor based in Dongguan, China. He has made significant contributions to the field of motor control technologies, holding a total of 4 patents. His innovative work focuses on enhancing the efficiency and safety of electric vehicles through advanced motor angle detection and diagnosis systems.

Latest Patents

Kong's latest patents include a motor angle detection and diagnosis apparatus, a motor controller, and methods related to electric vehicles. The motor angle detection and diagnosis apparatus is designed to connect to a drive motor using a resolver. This resolver outputs a feedback signal that represents the electrical angle of the drive motor. The apparatus features an angle sampling and diagnosis system that performs two-channel simultaneous sampling on the resolver feedback signal. It calculates both a first and a second electrical angle, diagnosing the data in real time. If any abnormalities are detected, the system can control the motor controller to enter a safe state.

Additionally, his work on the motor controller applied to electric vehicles involves a microprocessor and a sampling trigger method. This method includes a signal generation module that produces an exciting fundamental wave signal to drive the resolver. The signal processing module determines an exciting symbol based on this signal, which includes alternating high-level and low-level signals. The phase shift processing module then processes the zero crossing point signal to generate a sampling trigger signal for the microprocessor. This innovative approach reduces the number of peripheral circuits required, thereby enhancing product integration.
