Title: Ken Takeda: Innovator in Electrical Machine Technology

Introduction

Ken Takeda is a prominent inventor based in Anjo, Japan, known for his contributions to electrical machine technology. With a total of 8 patents, Takeda has made significant advancements in the field, particularly in the design and functionality of electrical machines.

Latest Patents

Among his latest patents, Takeda has developed a stator that features a stator winding within a stator core, which includes phase windings. A neutral-point bus bar connects to a coil end portion of the stator winding in a radial direction. This design includes first and second end portions that are joined together, with the first tip end extending in a fixed direction in the circumferential direction, while the second tip end extends in the opposite direction. The neutral-point bus bar consists of a main body portion that extends circumferentially, with connection portions extending radially to connect to the phase windings without protruding towards the stator core.

Another notable invention is the hybrid excitation rotating electrical machine. This machine features a rotor with a shaft that extends axially on at least one side, along with first and second cores separated by a gap. The first magnetic poles are excited by a permanent magnet, while the second magnetic poles are not. These poles are alternately arranged in a circumferential direction, with differing polarities between the first cores. The design allows for efficient interaction between the magnetic poles across the axial gap.
