Utilizing a special structure, the gear has been integrated into the interior of the brushless motor. It is a completely new type of geared brushless motor. #SpecialStructure #HollowStructure

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 separate structure of the motor and gearhead leads to larger geared motors, making it difficult to miniaturize and lighten the system. The GSH series from Coreless Motor utilizes the unique structure of coreless motors to deliver 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 enabled overall space-saving for the 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. Please take a look at our brushless motor with an integrated gear structure that utilizes our special design.

basic information

In conventional geared brushless motors, the brushless motor and gear head are separate, which makes the geared brushless motor larger and complicates the miniaturization of the system. By utilizing one of the key features of the coreless structure, the "hollow structure," and incorporating gears into that part, we enable overall space-saving of the system. The gear ratio and allowable torque vary for each customer, so we will respond accordingly each time. **Features** - Industry-leading class "gear-integrated" brushless motor - Space-saving - We provide the desired rotation speed and torque. - Maximizes the high-speed rotation of the coreless motor - Excellent quietness due to the integrated gears For more details, please contact us or download the catalog.
