Title: The Innovative Mind of Long Fei Jian
Introduction
Long Fei Jian, a prominent inventor based in Shaanxi, China, is recognized for his significant contributions to the field of motor control technologies. With a total of four patents to his name, Jian continues to advance innovations that enhance the efficiency and performance of permanent magnet synchronous motors (PMSM).
Latest Patents
One of his latest patents is entitled "Catch Spin Method for Permanent Magnet Synchronous Motor with Sensorless Field Oriented Control". This innovative method introduces a motor control actuator capable of driving PMSMs utilizing sensorless Field Oriented Control (FOC). The actuator includes a sophisticated sampling circuit that generates measurement signals by assessing the back electro motive force (BEMF) of the PMSM while it rotates. A phase-locked loop (PLL) processes this measurement signal to derive both the amplitude and angle of the BEMF. Furthermore, the motor controller produces vital control signals by estimating the rotor angle and adjusting to both sets of two-phase alternating current (AC) voltage components. This system is particularly advantageous as it incorporates a catch spin sequence, which allows for an efficient restart of the PMSM even while it is in motion.
