Introduction

Dong Jin Cho is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of solenoid technology and magnetic contactors. With a total of 2 patents, his work showcases innovative solutions that enhance performance and efficiency.

Latest Patents

One of his latest inventions is a high-speed solenoid. This device features enhanced response characteristics, including a movable shaft that can move linearly in an axial direction. The solenoid comprises a movable coil unit coupled to the shaft and a magnetic field forming unit that creates a magnetic field perpendicular to the current flowing in the coil. When current is applied, the coil moves due to the magnetic field, resulting in improved response speed. The design significantly reduces the weight of the moving parts and minimizes the electrical time constant, leading to faster operation.

Another notable patent is the magnetic contactor. This device includes a moving core with a main core that is movable in length, along with first and second core plates at both ends. A coil is positioned around the main core, and a fixed core is arranged to form a magnetic path. A permanent magnet is placed between the coil and the fixed core, with specific arrangements to reduce gaps between components. This innovative design enhances the efficiency and reliability of the magnetic contactor.
