SMC contributes to the miniaturization and high torque of underwater robots.
In the field of underwater robots, high reliability under harsh conditions and efficient operation in limited spaces are required. In particular, underwater use carries the risk of corrosion, making the durability and longevity of motors important challenges. In response to these challenges, the soft magnetic composite (SMC) 'Somaloy(R)', which achieves both miniaturization and high torque density that were difficult to realize with conventional electromagnetic steel sheets, expands the possibilities for new motor designs. 【Application Scenarios】 - Propulsion motors for underwater robots - Drive motors for underwater work arms - Motors for driving underwater sensors 【Benefits of Implementation】 - Increased design flexibility for the entire underwater robot due to miniaturization and lightweight motors - Improved maneuverability underwater due to high torque density - Reduction in the number of parts and cost savings by accommodating complex shapes
