This interplay of magnetic fields and moving charged particles (the electrons in the current) generates the torque that makes the armature spin. The armature experiences a force described by the left-hand rule. The key to producing motion is positioning the electromagnet within the magnetic field of the permanent magnet (its field runs from its north to south poles). ![]() The armature, carrying current provided by the battery, is an electromagnet because a current-carrying wire generates a magnetic field invisible magnetic field lines are circulating all around the wire of the armature. The motor features a permanent horseshoe magnet (called the stator because it’s fixed in place) and a turning coil of wire called an armature (or rotor, because it rotates). ![]() But, how are they able to convert the electrical energy to the mechanical rotation? In other words, DC motors take electrical power through direct current and transform this energy into mechanical rotation. What is a DC Motor?Ī direct current (DC) motor is a type of electric machine that converts electrical energy into mechanical energy with the help of the magnetic field generated in the device. Even though you are a novice in programming with Arduino or creating electronics projects with DC motors, it is simple to use them with a few lines of code, and some necessary components, depending on which method you use, will be explained later. ![]() In this article, I will give you information about DC motors, also known as electronic motors, and how you can control them using Arduino to create electronics projects with mobility and agility easily.
