Title: Masayuki Terashima: Innovator in Induction Motor Control
Introduction
Masayuki Terashima is a notable inventor based in Sakura, Japan. He has made significant contributions to the field of electrical engineering, particularly in the area of induction motor control. With a total of 2 patents, Terashima's work has advanced the efficiency and functionality of motor systems.
Latest Patents
One of Terashima's latest patents is a vector control method and system for an induction motor. This innovative approach combines decoupling calculation and 2-3 phase transformation to simplify system configuration. The method also adjusts the plus and minus signs of trigonometric signals based on the rotational direction, enabling four-quadrant operation. Additionally, for a 3-phase induction motor driven by a PWM inverter, the number of triangular wave signals generated during one period of the power supply signal is increased as the frequency of the supply voltage signal decreases. This enhancement improves response characteristics when the motor operates at low speeds. Furthermore, an initial supply voltage signal with a predetermined frequency is applied to the triangular wave signal generator when the motor stops, generating an initial secondary magnetic flux before the motor starts.
