Title: Yohei Kameda: Innovator in Motor Technology
Introduction
Yohei Kameda is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of motor technology, holding a total of 5 patents. His innovative designs focus on enhancing the efficiency and functionality of motor components.
Latest Patents
Kameda's latest patents include a stator core, stator unit, and motor. The stator core is designed by stacking multiple core plates, which are housed inside a motor case. This design features an elastic protrusion-equipped core plate that includes several elastic protrusions arranged in a circumferential direction. These elastic protrusions extend radially outward from the core plate's outer peripheral portion and are bent in an axial direction. The stator core is supported by the case while the elastic protrusions maintain contact with the inner peripheral face of the case, allowing for elastic flexing.
Another significant patent is related to a rotor manufacturing method. This rotor consists of a rotor core made from laminated steel plates and includes a magnet insertion hole that extends along the rotor core's axial direction. A resin is interposed between a permanent magnet placed in the magnet insertion hole and the inner wall face of the hole. The manufacturing method involves several processes, including integrating the permanent magnet with resin to create a resin-coated permanent magnet, press-fitting it into the magnet insertion hole, heating the rotor core to soften the resin, and finally cooling the rotor core.
