產業脈動｜高效能馬達於足型機器人的應用

機器人驅動方式可分為液壓驅動、氣體驅動和馬達驅動三種，其中馬達驅動是目前應用最廣泛的方式，具有高精度、即時響應等優勢，被評估適合今日AI機器人的發展。馬達種類眾多，根據不同方式可以劃分為不同種類。空心杯馬達產生的轉矩均勻分布，在低速運轉下保持平穩運行，在高速運轉下有著較少的震動和噪音，加上具有突出的節能特性、靈敏方便的控制特性和穩定的運轉特性，技術優勢十分明顯。無框力矩馬達具備體積小、功率高、低轉速輸出大扭矩等特性，這2種高效能馬達已成為人型機器人關節驅動的主流馬達。馬達作為機器人核心零組件，是機器人能靈活行走的重點技術之一。未來仿生足型機器人實現量產，將進一步驅動這些高效能馬達的需求。隨著仿生足式機器人量產，相關產業應有更多的發展機會。目前歐美日馬達公司的技術水準、產品能力仍領先全球，不過國內的法人單位和企業正不斷深化自主研製的能力，提升產品水準，為未來機器人的應用建立堅實基礎。

Robot driving methods can be divided into three types: hydraulic drive, gas drive and motor drive. Among them, motor drive is currently the most widely used method. It has the advantages of high precision and instant response, and is assessed to be suitable for the development of today's AI robots. There are many types of motors, which can be divided into different categories according to different methods. The torque generated by the hollow cup motor is evenly distributed, maintaining smooth operation at low speeds and having less vibration and noise at high speeds. In addition, it has outstanding energy-saving characteristics, sensitive and convenient control characteristics, and stable operation characteristics, and its technical advantages are very obvious. Frameless torque motors have the characteristics of small size, high power, and high torque output at low speed. These two types of high-efficiency motors have become the mainstream motors for driving humanoid robot joints. As the core component of the robot, the motor is one of the key technologies that enables the robot to move flexibly. The mass production of bionic foot-like robots in the future will further drive the demand for these high-efficiency motors. With the mass production of bionic legged robots, related industries should have more development opportunities. At present, the technical level and product capabilities of European, American and Japanese motor companies are still leading the world, but domestic legal entities and enterprises are constantly deepening their independent research and development capabilities, improving product standards, and laying a solid foundation for the future application of robots.
