The simple electric motor consists of a rotary electric conductor (rotor), which is located between the north and south poles of a fixed magnet in the form of a horsetail. The connector is known as the rotor (sometimes called the holster), while the permanent magnet is known as the field structure (the constant member). Fixed member: The structure of the field, the member's permanent winding generate a magnetic field within the engine, where the magnetic field consists of power lines between the poles of the fixed magnet. The field structure is made up of a simple DC motor from a permanent magnet called a field magnet. In some larger and more complex engines, the structure of the field consists of more than one electromagnet that feeds electricity from an external source. Such magnetic magnets are called static domain winding.

Rotator or rotor: The rotor is a cylindrical coil or winding in a total cylindrical shape, which is an electromagnet when the current passes through it. The rotor is connected to an axis based on two loading rods, and the load is connected to this axle and the load is rotated.
The rotor is rotated in small, simple DC motors between the two magnet poles (either a self-magnet or an electric magnet), where the northern magnetic rotor pole is attracted to the south pole of the fixed member, and the south is in the north with that. The current of the current is then reversed to change the north rotor pole to make it a south pole, so the southern poles avoid, making the portfolio half-cycle. The current is reversed by an electric exchanger - a metal loop divided into several parts, two of which are connected to two external currents and the exchanger connects the current to the rotor member. In contrast to the current in the rotor through the exchanger becomes poles corresponding to the poles of the different area of the fixed member complete rotary movement and a full cycle. By turning the DC current in the rotor coil, the rotor continues to rotate.

Each time the direction of the current is reflected (in practice the current flows in the winding from the right and is constantly left from the left, but during this time the exchanger has half the cycle with the coil in question, and the direction of the inward current becomes opposite to its first direction). When the holster rotates, it breaks the lines of magnetic forces generated by the fixed member's field. It produces an electrical voltage in the coil. This electrical voltage is called a reverse electric driving force that reduces the speed of rotation of the clipboard, as it reduces the current you carry. If the engine runs a simple load, the clip will rotate at a high speed and generate a more opposite electric impulse. As the load increases, the holster rotates slower as it cuts fewer magnetic lines. Therefore, the engine carrying a larger load works more efficiently because it uses less energy to operate.

Electrical Exchanger: The exchanger is mainly used in DC motors, which reflects the current of the current in the rotor when it rotates. It connects the power source to the rotor. The exchanger in the DC motor consists of a loop divided into at least two parts and is installed in the shaft connected to the rotor. The end of each rotor profile is related to two parts of the metal ring (forming two opposite poles). The current from the external source is connected to the exchanger by two wires and two small pieces of graphite called the "Brushes" and two opposite parts of the exchanger's parts are connected. And enters the current from the brush to the winding, and there is another brush in the other side of the exchanger out of the current of the lap and return the current to the source of electricity. When one of the rings is connected to the first brush, the power is picked up from the brush and sent through the clipboard. When the magnetic poles on the clipboard form some of the similar poles of the field magnet, the holster rotates half a passing cycle in one of the gaps separating the rings. The second ring of the exchanger then connects to the first brush and becomes the current carrier to the clipboard. This reverses the current of the current and reflects the position of the electrodes in the clipboard. When the same poles meet the magnetic fields of the fixed member and the holster, the portfolio continues to rotate due to the variation of their magnetic fields.
