Title: Masaharu Maruno: Innovator in Electromagnetic Brake Control Technology
Introduction
Masaharu Maruno is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of electromagnetic brake control technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and reliability of braking systems in various applications.
Latest Patents
One of his latest patents is the "Non-excited operation type electromagnetic brake control device and method." This invention addresses the issues of vibration noise and frequent switching when reducing the average current flowing through a brake coil in a holding state. The device utilizes an acute triangle voltage wave generation unit to create a stepped acute triangle voltage wave, which alternates between valley and peak parts. A comparative voltage wave generation unit then generates a comparative voltage wave based on the current through the brake coil. The comparison unit evaluates these waves to control the current supply to the brake coil effectively.
Another significant patent is the "Control device for hoist and control method thereof." This invention simplifies the judgment of a hoist brake's lifetime. It includes a time setting unit that adjusts the timing of brake engagement and disengagement based on the startup of a double winding induction motor. The device can also adapt to different power supply frequencies, ensuring optimal performance.
