Brushed motors were the first commercially important application of electric power to driving mechanical energy and dc distribution systems were used for more than 100 years to operate motors in commercial and industrial buildings. Small dc motors are used in tools toys and appliances.

The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances.
Dc motor wikipedia. A brushed dc electric motor is an internally commutated electric motor designed to be run from a direct current power source. A dc motors speed can be controlled over a wide range using either a variable supply voltage or by changing the strength of current in its field windings. An electric motor is an electrical machine that converts electrical energy into mechanical energymost electric motors operate through the interaction between the motors magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.
Electric motors can be powered by direct current dc sources such as from batteries motor vehicles or rectifiers. A brushless dc electric motor bldc motor or bl motor also known as electronically commutated motor ecm or ec motor and synchronous dc motors are synchronous motors powered by dc electricity via an inverter or switching power supply which produces an ac electric current to drive each phase of the motor via a closed loop controller.
