Title: Innovations of Takehiro Kobayashi
Introduction
Takehiro Kobayashi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of rotating-electric machines. With a total of 6 patents to his name, Kobayashi continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is focused on a rotating-electric machine designed for use in engine starters. This innovative machine improves power efficiency by reducing the inductance of the coil. The design features an armature located inside a stator, where the armature winding is inserted into a slot. The winding is configured as a wave winding and a short-pitch winding. In a specific case where the number of poles is 2p=6 and the number of slots is Ns=23, the armature windings are inserted into the first to fourth slots. This configuration establishes a back pitch of yb equal to 3, resulting in a short-pitch degree of δ (|Ns/2p−yb|) of 0.83, satisfying the expression of 0.5<δ<1. Another notable patent addresses the design of a starter that prevents the attracting force to the plunger from becoming insufficient. In this design, at least one of the output shaft or thrust spline is made from a magnetic material with a lower relative permeability than iron.
