A Direct Current Motor has 6 essential parts: armature, or rotor; commutator; brushes; axle; field magnet; and a DC power supply. With an understanding of magnets and magnetism, these 6 parts become a motor.The first step in understanding a dc motor is an electromagnet. An electromagnet is a magnet consisting, essentially, of a coil of insulated wire wrapped around a soft iron core that is magnetized only when current flows through the wire. Simple put, an …

…advancements became more and more complex with time, eventual evolving into the electric motors so widely used today. After the invention of the induction motor, alternating current machines largely replaced DC machines in most applications. However, DC motors still have many uses. After more than a century, DC motors are still in widespread use and thanks to many limited space applications that show no signs of disappearing, they'll be around for many years to come
