An electronically commutated motor (ECM) is a type of electric motor that combines the benefits of both AC and DC motors, offering high efficiency, reliability, and variable speed control. ECMs are brushless DC motors that are controlled electronically, rather than mechanically. Their design and electronic commutation capabilities make them suitable for a wide range of applications where energy efficiency and variable speed control are important. ECMs are increasingly becoming popular in industries, such as heating, ventilation, and air conditioning (HVAC), refrigeration, industrial automation, home appliances, and automotive

Drilling rigs are machines that are used to drill a wellbore at oil and gas reserves for the extraction of hydrocarbons. In onshore drilling, drilling rigs include virtually all components required for the drilling process. While in offshore drilling, drilling rigs include the same components as onshore drilling rigs, but not those of the drilling platforms or vessels themselves. The major components of the drilling rig include a mast or derrick, mud pumps, mud tanks, rotary tables, drillstring, draw works, power generation equipment, and other auxiliary equipment. Oil and gas upstream companies hire drilling rig contractors to drill oil and gas wells.

Energy-based aesthetic devices are medical technologies that use various forms of energy, such as light, heat, sound waves, or electromagnetic fields, to improve the appearance of the skin. These devices are commonly used in aesthetic clinics and medical spas for treatments like skin rejuvenation, wrinkle reduction, fat reduction, and hair removal.

精密减速器：匹配转速、传递转矩的核心传动元件。精密减速器种类较多，包括谐波减速器、RV减速器、精密行星减速器等。谐波、RV、行星减速器具有不同的特点，适用于不同的应用场景。谐波减速器具有单级传动比大、体积小、质量小、运动精度高并能在密闭空间和介质辐射的工况下正常工作的优点，使其在机器人小臂、腕部、手部等部件具有较强优势。行星减速器结构相对简单，体积相对较小，单级传动比范围相对有限，适用于机器人的下肢。RV减速器 传动比范围大、精度较为稳定、疲劳强度较高，并具有更高的刚性和扭矩承载能力，在机器人大臂、机座等重负载部位拥有优势。
