Title: Jun Nakano: Innovator in Electromagnetic Actuators

Introduction

Jun Nakano is a notable inventor based in Iruma, Japan. He has made significant contributions to the field of electromagnetic actuators, holding a total of 2 patents. His work focuses on innovative designs that enhance the functionality of valve systems.

Latest Patents

One of Nakano's latest patents is an electromagnetic actuator for a valve stem. This invention features a stator core with concentratedly wound coils around salient poles, positioned outside a nonmagnetic tubular member. The actuator includes a rotor inside the tubular member that drives a threaded operating shaft, allowing for the reciprocal operation of an objective member. The design incorporates permanent magnets arranged along the surface of each salient pole, with induction teeth formed on the rotor's circumference. This configuration enables the rotor to function as a pulse motor through alternating excitation of the coils.

Another significant patent is the motor-operated valve, which consists of a stator outside a nonmagnetic tubular member that allows fluid flow. The stator coils are wound around multiple magnetic poles, with permanent magnets secured to each pole's operating surface. The rotor, supported inside the tubular member, features induction teeth that match the pitch of the permanent magnets' pole-pairs. This design includes a mechanism for converting the rotor's rotational movement into linear movement for a valve member.
