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, appeals to its members (approximately 30,000) by publishing an in-house web magazine that covers societal 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 in-house newsletter published by the Toyota Technical Association. The "GS Series" is a lightweight and compact high-efficiency geared motor that incorporates 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. Since there is no iron core, there is no iron loss that causes heat generation, allowing for high output through high-speed rotation. This special technology is attracting attention from major automotive manufacturers, including Toyota Motor Corporation. 【Features】 - Lightweight and compact yet powerful due to the special coreless structure - Suitable for small applications requiring high-speed rotation - Capable of producing motors tailored to your desired rotation speed and torque - Production with encoders and brakes is also possible For more details, please contact us or download the catalog.

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, adding silent mode to 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 not only the clarity of photos but also enabled the reading of QR codes. The aforementioned coreless motors had very low output, but I have developed various technologies that overcome the weaknesses of coreless motors while enhancing 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 provide explanations until you understand.

Applications/Examples of results

To 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, making geared motors larger and complicating the miniaturization and weight reduction of 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 this hollow section, 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, electric tools, and many more.
