To contribute to the miniaturization of machines, a compact gear is built into the brushless DC motor. This contributes to the miniaturization of all types of machinery. #Miniaturization of machines

The gear-in-motor "GSH Series" is a high-efficiency geared motor with a lightweight and compact design that contributes to the miniaturization of machines by incorporating a small planetary gear within a coreless structure motor. By serving as an alternative to products with gear heads, it contributes to system miniaturization. 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), compact conveyors, and small machinery. 【Features】 - Lightweight and compact with powerful performance due to the special coreless structure - Capable of handling small applications that require high-speed rotation - Excellent quietness due to the built-in small planetary gear - Adjustable to desired rotation speed and torque - Achieves miniaturization of geared motors by placing small gears inside the motor - Customizable motors can be produced by adjusting the gear ratio - Options for encoders and brakes are also available For more details, please contact us or download the catalog.

basic information

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, which causes geared motors to become large, making it difficult to miniaturize and lighten the system. The GSH series from Coreless Motor delivers high 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 into 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 making the impossible possible with you. With this aspiration in mind, we support our customers in the miniaturization of motors. [Applications for FA Equipment] - Small robots - Small AGVs - Small unmanned transport vehicles - Small assistive carts - Small unmanned carts and other general FA equipment.
