A compact gear is built into the motor! It can deliver high torque while maintaining the same motor size. *Basic knowledge document: Special presentation of technical materials on the gear-integrated motor!

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. This is achieved by utilizing the hollow structure, which is one of the features of the coreless design. By embedding the gears in the hollow section, it enables space-saving for the entire system. Furthermore, by placing the gears inside the motor, it also 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. Since there is 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), small transport robots, and compact 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 ■ Adjustable to desired rotation speed and torque; custom motors can be manufactured! ■ 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 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 that 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 the moment when what was once impossible becomes 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 others.
