Title: Shigeo Inaki: Innovator in Electric Motor Technology

Introduction

Shigeo Inaki is a notable inventor based in Takefu, Japan. He has made significant contributions to the field of electric motor technology, holding a total of 4 patents. His innovative approaches have led to advancements in motor assembly and design.

Latest Patents

One of Inaki's latest patents is a method of assembling a stator for an electric motor. This method involves dividing the stator into a pole portion and a yoke portion, with a winding on the insulated pole portion. The yoke portion is forcibly enlarged outwardly, allowing the tip ends of the projections of the pole portion to fit into the recesses of the yoke portion. The design ensures that the opposing surfaces of each recess are parallel, and the bottom surface is aligned with the outer peripheral surface of the yoke portion. This innovative assembly technique reduces the press-fitting load, making it easier to assemble large-sized stator iron cores and improving the properties and output of electric motors.

Another significant patent by Inaki is a method of making a resin-molded motor. This motor consists of a rotor and a laminated stator with axially and radially extending slots that define pole pieces. The resin material is molded within the slots for insulation and bonding, while a cylindrical resin material shroud extends from each end of the stator. The design includes a steel sheet bracket that supports the rotor and a connector for supplying power to the windings. This comprehensive approach enhances the efficiency and functionality of the motor.
