Title: Kazunari Koga: Innovator in Motor Control Systems and Lawn Care Technology

Introduction

Kazunari Koga is a prominent inventor based in Hyogo, Japan, known for his significant contributions to motor control systems and lawn care technology. With a total of 18 patents to his name, Koga has demonstrated a commitment to innovation and engineering excellence.

Latest Patents

Koga's latest patents include a motor control system designed for electric motor-driven vehicles. This system features a drive motor and a deck motor connected to a battery, an ECU, and a key switch. The key switch detects when the operation unit is activated and sends a restart permission signal to the ECU. When the state of charge (SOC) of the battery falls below a predetermined threshold, the ECU disables all motors. Upon receiving the restart permission signal, the ECU enables a decelerated traveling mode, allowing the drive motor to operate at a reduced speed.

Another notable invention is his riding lawnmower, which includes left and right wheels, at least one caster wheel, and a lawnmower blade or reel. The left and right wheels are independently driven by electric rotary machines, allowing for precise maneuverability. The control section responds to turn instructions from the operator, adjusting the wheel speeds based on either standard or deceleration setting conditions. This innovative design enhances the efficiency and effectiveness of lawn care.
