Electrical power tools come in a large variety of shapes, sizes, and power ranges, and can be used for building, plumbing, electrical installments, gardening, home repair and maintenance, in both professional and do-it-yourself (DIY) use cases.

Carpentry, Concrete and Metal Work

重型施工和拆卸工具(如锤子、横截锯、磨床和扳手、圆锯和往复锯,以及DIY爱好者经常使用的小型手钻和螺丝刀)具有不同级别的功率、扭矩配置、成本和尺寸,使得选择合适的电机对于最终用户来说颇具挑战性。在通用电机仍在使用(因为通用电机为传统和入门级施工和拆卸工具提供了简化的电机驱动)的背景下,低压无刷直流电机为自己赢得了一席之地,因为此类电机在无绳工具中拥有出众的可靠性和功率/重量比,其电池总重接近于工具本身的重量。

Plumbing

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。

Vacuum and Blowers

Both vacuum cleaners and blowers use a fan to create a pressure difference that results in air flow, generating suction in vacuum cleaners or blowing in driers, according to the mechanical construction of the propeller fan. Wet-dry vacuum cleaners ar

The trends towards safer, smarter power tools

Depending on their mission profile and whether or not the task at hand requires a torque, power tools can be based on brushed DC, 3-phase brushless DC (BLDC), or universal motors. While still popular, electrical tools that are directly powered from the AC main supply are gradually being replaced by battery-operated equipment. However, cordless power tools often come with a trade-off between weight, power, and battery run-time before recharge.

Power tools are also becoming smarter thanks to embedded sensing features to further enhance performance, usability (by reducing torque ripple for example), and security (preventing dangerous kick-back for instance). Connectivity features are also increasingly implemented in recent designs, as connecting power tools to smartphones or tablets can enable data collection and statistical analysis, for condition monitoring and predictive maintenance purposes. GNSS/GPS as well as other suitable technologies, including LoRA or Sigfox protocols, can help geolocate power tools inside large construction areas and be used for anti-theft purposes. 

Our products and solutions for motor control

ST offers a wide range of motor control solutions to fit the large variety of motor types and power ratings found in power 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.
