GS Series

  • Official site

Our gear-integrated motor has been featured in the newsletter "TES MAGAZINE" of the Toyota Technical Association (a volunteer organization within Toyota Motor Corporation).

The Toyota Technical Association, as a volunteer technical organization of Toyota Motor Corporation, is appealing to its approximately 30,000 members by publishing an internal web magazine that covers social transformation, cutting-edge technologies, and the passion of developers, without being confined to the industry. We would like to inform you that our gear-integrated motor, the "GS Series," has been featured in the internal newsletter published by the Toyota Technical Association. The "GS Series" is a high-efficiency geared motor designed to be lightweight and compact, incorporating a small planetary gear within a coreless motor. By integrating gears into the hollow space created by the coreless structure, we achieve space-saving design. This contributes not only to the miniaturization of systems and robots but also to improved quietness. Due to the absence of an iron core, there is no iron loss that causes heat generation, enabling high output through high-speed rotation. This special technology is attracting attention from major automotive manufacturers, including Toyota Motor Corporation. 【Features】 ■ Lightweight and compact with powerful performance due to the special coreless structure ■ Suitable for small applications requiring high-speed rotation ■ Customizable motor production by adjusting rotation speed and torque ■ Production with encoders and brakes is also possible *You can view detailed product information by downloading the PDF.

basic information

People who have dedicated their lives to "surprising the world" with their unique ideas. Fascinated by coreless motors, I have developed: - Fan motors for cooling computer ICs, contributing to the miniaturization of computers through adoption by Intel. - Vibration motors for mobile phones, leading to the addition of silent mode in mobile phones through adoption by Motorola. - Autofocus linear motors for smartphones (automatic camera focus function), with Sharp releasing the world's first autofocus-equipped mobile phone, followed by Apple incorporating it in the iPhone 3GS, making it a standard feature today. The autofocus function has improved photo clarity and enabled QR code scanning. The coreless motors mentioned above had very low output, but I have developed various technologies that overcome the weaknesses of coreless motors while leveraging their characteristics, such as high output through high-speed rotation and gear-integrated motors utilizing a hollow structure. There are some technologies that cannot be disclosed at this time, so if you visit, I will explain them to your understanding. We look forward to your visit.

Applications/Examples of results

For those struggling with the miniaturization of robots, we have a new proposal from Coreless Motor Co., Ltd. A reliable robot that demonstrates great power in a small body. Just imagining it is exciting, isn't it? Unfortunately, with conventional motors, the motor and gearhead are separate, which causes geared motors to become larger, making it difficult to miniaturize and lighten the system. The GS series from Coreless Motor delivers high torque while maintaining the size of the motor. The significant difference comes from utilizing one of the core features of the coreless structure: the hollow structure. By incorporating gears within that hollow part, we have made it possible to save space for the entire system. Furthermore, by placing the gears inside the motor, we also contribute to the quietness of the geared motor. We want to share the joy of making what was once impossible, possible, with you. With this aspiration in mind, we support our customers in the miniaturization of motors. - Robot equipment, industrial machinery, mobile robots, transport robots, medical devices, agricultural machinery, power tools, and many more.
