Title: The Innovative Contributions of Katuyuki Tanaka
Introduction
Katuyuki Tanaka is a notable inventor based in Kawasaki, 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 rotation control motors.
Latest Patents
One of his latest inventions is the Rotation Control Motor. This motor comprises a shaft, an armature with a core that has teeth 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 engages to stabilize the motor's speed through magnetic flux.
Another significant patent is the Moving Material Electric Control Device. This motor consists of a yoke as the casing, a shaft extending through the center, 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 on 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.
