A mechanized tool that uses a motor or electromagnet as the power and drives the working head through a transmission mechanism is called an electric tool. It is a tool for holding and operating by hand, using a small-power motor or electromagnet as power, and driving the working head through a transmission mechanism.
In 1895, Germany manufactured the world's first DC electric drill. The shell is made of cast iron and can drill 4mm holes in the steel plate. Then there was a three-phase power frequency (50Hz) electric drill, but the motor speed failed to exceed 3000r/min.
In 1914, electric tools driven by single-phase series motors appeared, and the motor speed reached more than 10000r/min.
In 1927, an intermediate frequency power tool with a power supply frequency of 150-200Hz appeared. It not only has the advantages of high speed of single-phase series motors, but also the advantages of simple and reliable three-phase power frequency motors. However, because of the need for intermediate frequency current power supply , Use is restricted. Common power tools include electric drills, electric grinders, electric wrenches and electric screwdrivers, electric hammers and impact drills, concrete vibrators, and electric planers.
