DC motor is an electric machine that uses DC power to create mechanical force and rotation. DC motors are known for their ability to spin quickly and provide high starting torque, which makes them useful in many applications, including power tools, appliances, electronics, and automotive applications. DC motors can be categorized into two main groups: brushed and brushless. Brushed DC motors use graphite and carbon brushes to conduct current from an external circuit to the commutator, which then supplies current to the armature winding. Brushless DC motors are another type of DC motor.
