Title: Tetsuo Oishi: Innovator in Linear Motor Technology
Introduction
Tetsuo Oishi is a notable inventor based in Ise, Japan, recognized for his contributions to the field of linear motor technology. He holds a total of 3 patents, showcasing his innovative approach to engineering and design.
Latest Patents
One of Oishi's significant inventions is the linear DC brushless motor. This motor is designed based on the principle of transforming a conventional DC brushless motor into a linear configuration. The design necessitates a stator with numerous permanent magnets arranged linearly, with adjacent poles separated by gaps. The armature core also has a finite length at each end, which affects the performance of the motor. Oishi's design addresses the issue of synthesized detent thrusts that can hinder the application of this motor in office automation devices and precise measuring instruments. He proposes solutions such as reducing the unit volume of the teeth at the axial ends of the armature core to mitigate these detent thrusts.
Another notable patent is a transporting apparatus utilizing a linear motor. This apparatus consists of a primary unit and a secondary unit, with the primary unit generating a progressive magnetic field through coils supplied with three-phase alternating currents. The secondary unit includes a core and permanent magnets, allowing for controlled transportation along the secondary unit.
