Title: Innovations of Inventor Hung D Vu
Introduction
Hung D Vu is an accomplished inventor based in Pembroke, MA (US), known for his significant contributions to the field of motor technology. With a total of six patents to his name, he has developed innovative solutions that enhance the performance and reliability of stepper motors.
Latest Patents
One of his latest patents is titled "Method and apparatus for misstep detection and recovery in a stepper motor." This invention utilizes a position-feedback device with a resolution capability as low as 200 counts per motor shaft revolution. It effectively detects missteps and facilitates motor step recovery. The system computes position deviation periodically by subtracting the feedback position from the commanded position, allowing for the determination of the load angle and the motor's operating status. If the load angle remains within an established range, the motor operates normally. However, if it exceeds this range, the system controller takes immediate action to recover lost motor steps and reestablish synchronism, minimizing downtime.
Another notable patent is for an "Integrated electric motor and drive, optimized for high-temperature operation." In this design, heat-generating components are strategically placed near the motor body for efficient heat dissipation, while heat-sensitive components are physically and thermally segregated. This innovative approach enhances the reliability and performance of the motor system under high-temperature conditions.
