Title: The Innovative Mind of Takato Doi
Introduction
Takato Doi, an accomplished inventor based in Fukuoka, Japan, has made significant contributions to the field of linear motor technology. With a total of two patents to his name, Doi has established himself as a key player in the innovations surrounding high-performance electric motors.
Latest Patents
Doi's latest inventions focus on enhancing linear motor performance. The first patent describes a moving-coil linear motor that is free of cogging. This innovative motor features a rotor composed of separated block cores, each equivalent to eight times the magnet pitch and equipped with nine teeth along its length. The block cores are strategically arranged with gaps equivalent to two-thirds of the magnet pitch to optimize efficiency. Additionally, the armature coils are designed to differ in phase by 120 degrees, effectively negating the cogging effects caused by the blocks.
The second patent also relates to a linear motor, characterized by a row of permanent magnets that establish a field system. In this invention, the armature is oriented orthogonally to the magnetic field, and the core contains winding accommodation grooves formed in the armature iron plates. By laminating the iron plates and aligning them with the rolling direction of the electromagnetic steel plates, Doi enhances the magnetic flux density and peak thrust of the motor.
