Power Tools

Overview
Documentation
Tools and Software
Solutions
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
Heavy-duty construction and demolition tools, such as hammers, cut-off saws, grinders and wrenches, circular and reciprocating saws, as well as small hand-drills and screw drivers that are often used by DIY enthusiasts, offer different levels of powe

Plumbing
Professional tools used in construction for cutting and/or bending iron rods, crimping, and cutting tools, as well as pressing tools for bending, cutting, or joining pipes, are generally operated by an electric motor. The motor transmits the force to

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.
