Compact gear built into the motor! It can deliver high torque while maintaining the same motor size. *Exhibited at the trade show.

The Gear-in-Motor "GMH Series" is a high-efficiency geared motor designed with a lightweight and compact structure, incorporating a small planetary gear within a coreless motor. Utilizing the hollow structure, which is one of the features of the coreless design, we have achieved this integration. By embedding the gears in the hollow section, we have enabled space-saving for the entire system. Furthermore, placing the gears inside the motor contributes to the quietness of the geared motor. By serving as an alternative to products with gear heads, it contributes to the miniaturization of systems and robots. With no iron core, there are no losses that cause heat generation, allowing for high-speed rotation. It is widely used in small AGVs (automated guided vehicles), compact transport robots, and small robots! 【Features】 ■ Lightweight and compact yet powerful due to the special coreless structure ■ Suitable for small applications requiring high-speed rotation ■ Excellent quietness due to the embedded small planetary gear ■ Customizable to desired rotation speed and torque; motors can be manufactured to your specifications! ■ Achieves miniaturization of geared motors by placing small gears inside the motor ■ Options for encoders and brakes are also available For more details, please download the catalog or contact us.

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 with 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 significant torque while maintaining the size of the motor. The key difference comes from utilizing one of the main 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. Additionally, 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 the impossible possible with you. With this aspiration, 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.
