主要产品
建筑行业中用于切割和/或弯曲铁棒、压接和切割工具的专业工具,以及用于折弯、切割或连接管道的冲压工具,通常由电动马达带动。电机 将力传递给机械臂,需要用到一个复杂的齿轮系统(比如用于施工的折弯工具),或者基于液压泵(使用油液传递压力,并将其转换为力/扭矩)。最合适的管道施工电机类型取决于设备的类型、型号、尺寸和功率。 通用电机或感应电机通常用于建筑行业中的重型机械;而无刷直流(BLDC)电机最常用于手枪式握把或直插式冲压工具,可以由电池组供电,或连接交流电源。 阅读更多

Key challenges

Pressing is a way to join metal pipes, that uses force/pressure to make a connection between two parts, eliminating the need to solder, and enabling fast professional repairs. It requires calibrated jaws and pressing rings to which a very tightly controlled force must be applied to ensure a perfect sealing and avoid any equipment damage. With this comes the need for certified accessories. The tool itself needs to be recalibrated after a predefined number of use cycles, which is accounted for by an internal counter, sometimes based on a Human Machine Interface. The tool is automatically disabled after the maximum number of cycles has been reached. As this information needs to be recorded and stored over time for both result quality and user safety, many plumbing tools are nowadays connected over Bluetooth® LE to mobile phones or tablets, where data on the tool usage can be stored and analyzed.

 

Our products and solutions

ST offers a wide range of motor control solutions to fit the large variety of motor types and power ratings found in plumbing tools. Our offering includes an extensive range of 32-bit microcontrollers equipped with a set of hardware peripherals and software development tools, including System-in-Package (SiP) solutions featuring an STM32 microcontroller and a monolithic 3-phases driver (STSPIN32 family), which are ideal for space-constrained tools such as hand-held drills. Our range of power discrete solutions, such as IGBTs, thyristors, and power MOSFETs available in several types of packages, including power modules and intelligent power modules, can contribute to making power tools lighter and more energy-efficient. In addition, our broad range of inertial and environmental MEMS sensors can also make power tools smarter and more connected.
