Title: Koichi Takeda: Innovator in Fan Technology and Motor Control
Introduction
Koichi Takeda is a notable inventor based in Fukuroi, Japan. He has made significant contributions to the fields of fan technology and motor control, holding a total of 2 patents. His innovative designs reflect a deep understanding of engineering principles and practical applications.
Latest Patents
One of Takeda's latest patents is for an axial fan. This axial fan comprises an impeller, which includes a hub and a plurality of blades arranged on the outer circumference of the hub. A pressure surface of each blade is at least partially a convex surface that bulges from the suction surface side to the pressure surface side. This convex surface is strategically positioned within a predetermined region of the pressure surface of the blade on the hub side, which is part of the radial width of the blade.
Another significant patent is for a control device for a stepping motor and its control method. This device gradually increases the absolute value of the excitation current in phase A from the start until the end of the hold period. The amount of change in the excitation current per unit time is controlled to be smaller than or equal to a first predetermined value. During the hold period, the absolute value of the excitation current in phase B also gradually increases, ensuring a smooth transition to one-phase excitation operation.
