The challenge was to continue using a potentiometer to control tool speed without having to pass the high current through its resistive component. Additionally, we saw the emergence of green energy solutions and their integration into all forms of design. However, in the 20th century, the emergence of high-energy density batteries changed this. Or it could be something slightly more sophisticated, such as a potentiometer, allowing the user to specify how much energy flows from source to motor.įor the first 100 years of electric power tool development, a power source, a motor and a switch/potentiometer were all that was needed to design and fabricate drills, sanders, grinders, screwdrivers, blowers, saws, etc. This component could be as simple as an interrupter, controlling whether there is a current flow. Many of today’s tools have moved to the tri-phase BLDC motor topology.įinally, a switch is employed to control the source-to-motor energy transfer. This motor can be a Universal AC/DC brushed motor, a brushed DC motor, or a brushless DC (BLDC) motor. The second component is an actuator of sorts, or a motor that will transform the electric energy into mechanical energy. The Lithium Ion based battery has become the most prominent because of its increased energy density, as well as resilience to hold a charge. Cordless or wireless power tools – rely on the electric energy stored within batteries of different chemistries such as Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH) and Lithium Ion (LiIon).Corded tools – the power source is AC and needs to be plugged into the “wall” to operate.All electric-powered tools can be subdivided into two classes: corded and cordless. The first component of an electric power tool is the power source. Additionally, this blog outlines how the incorporation of brushless DC motors in power tools is providing a competitive edge for manufacturers. It also covers how the microprocessor and the brushless DC motor play an instrumental role in transforming the power tools we use today. This blog covers the key aspects of the cordless, battery-powered variant, including what's propelling the evolution and the challenges along the way. So, what’s fueling the evolution of power tools? Besides power tool enthusiasts, much can be attributed to the many advancements in semiconductor technology – most specifically with cordless power tools. Today, they are wireless, light, battery-operated, and work hard so we don’t have to. Over the course of the past century, power tools have noticeably evolved.
