Title: Innovations of Hiroyuki Kurihara

Introduction

Hiroyuki Kurihara is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of motor technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and stability of motor operations.

Latest Patents

One of his latest inventions is the Rotation Control Motor. This motor comprises a shaft, an armature with a core wound by wires to form coils, a commutator, and a field magnet. The armature core features multiple teeth, while the commutator has segments corresponding to these teeth. The coils include a normal coil and a brake coil. When the motor exceeds its expected rotation speed, the brake coil activates, using magnetic flux to stabilize the motor's speed.

Another significant patent is the Moving Material Electric Control Device. This motor consists of a yoke casing, a central shaft, an annular stator fixed to the yoke, and an armature that rotates with the shaft inside the stator. The armature has several teeth on its outer surface. A wire is wound around one of the teeth to create a normal coil, while another wire forms a brake coil that acts as a short circuit. When the motor rotates too quickly, the brake coil generates magnetic flux that counteracts the motor's rotation, allowing it to slow down.
