Title: The Innovations of Masakatsu Takahashi
Introduction
Masakatsu Takahashi is a prominent inventor based in Numazu, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of control devices for rotary electrical machines. With a total of 6 patents to his name, Takahashi continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is a control device for a rotary electrical machine. This device is designed to function both as a motor and a power generator. It includes a power conversion circuit that acts as an inverter for supplying drive current from a battery to the rotary electrical machine. Additionally, it serves as a rectifier for converting the power generation output of the machine back to the battery. The controller within the device ensures that the three-phase armature coils are short-circuited when the battery is disconnected, preventing excessive DC output voltage. Once the voltage decreases to a set low level, the short circuit of one phase is released, allowing only two phases to remain short-circuited.
Another notable invention is a starter generator that features a cuplike-shaped rotor yoke with magnets attached to its inner periphery. This generator includes a stator mounted on a bracket and is protected by a cover that forms a hermetically sealed casing. The design incorporates multiple fans on the rotor yoke's outer surface, which create a centrifugal effect to draw air through vent holes, enhancing the cooling efficiency of the generator.
