A Direct Current (DC) motor is a motor that turns energy from a direct current and turns this into mechanical energy. The first DC motor was developed around the 1830''s-1840s. They were commercially unsuccessful, because these motors were battry powered and batteries were still very expensive and the quality was low.
· CONSTRUCTION OF DC MOTOR. All DC machines mainly consist of two parts. One is the stator and the other is Rotor. The stator is a stationary part that includes yoke, pole, pole winding, and Interpoles. The stator produces the magnetic flux.
Construction, Working & Applications of BLDC (Brushless DC Motor) Brushless DC motors (BLDC) have been a much focused area for numerous motor manufacturers as these motors are increasingly the preferred choice in many applications, especially in the field of motor control technology.

· Before understanding the working of DC motor, first, we have to know about its construction. The armature and stator are the two main parts of the DC motor. The armature is the rotating part, and the stator is their stationary part. The armature coil is connected to the DC supply. The armature coil consists the commutators and brushes.

The DC motor was the mainstay of electric traction drives on both electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. The introduction of DC motors and an electrical grid system to run machinery starting in the 1870s started a new second Industrial Revolution.
DC Motors Although ac motors are used in most of the cases, DC motors have many applications and used for multi-purpose applications. DC Motor Principle A machine that converts dc power into mechanical energy is known as dc motor. Its operation is based on the principle that when a current carrying conductor is placed in a
· The DC Shunt-wound motor, running on Direct current, has its field windings placed in parallel to the armature. In Electrical terms, parallel is generally denoted as shunt. That is the reason behind naming it a DC Shunt motor. Same voltage is applied to both shunt winding and armature in this motor. This parallel configuration allows independent path of current for field winding and armature.
· Re-uploaded with updates: Details of construction and working of a dc motor is explained in this video.
· DC Motor. Electric motors turn electricity into motion by exploiting electromagnetic induction. A simple direct current (DC) motor is illustrated below. The motor features a permanent horseshoe magnet (called the stator because it''s fixed in place) and an turning coil of wire called an armature (or rotor, because it rotates).
A practical DC motor consists of the following physical components: o Magnetic frame (yoke) o Pole shoes o Field coil o Armature core o Armature winding o Commutators o Brushes o Bearings Magnetic frame (Yoke): o It is made of cast iron or rolled steel.
· A DC motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of the DC motor is that whenever a current carrying conductor places in the magnetic field, it experiences a mechanical force. Fleming''s left-hand rule and its magnitude decide the direction of this force.
Fig. 3 – (a) Working Principle of DC Motor (b) Fleming''s Left Hand Rule. This is a multi-polar DC Motor as shown in the Fig. 3. Here the terminals of the motor are connected to an external DC supply.Thus the Armature conductors carry current and the Field Magnets …
· A Brushless DC Motor is similar to a Brushed DC Motor but as the name suggests, a BLDC doesn''t use brushes for commutation but rather they are electronically commutated. ... Construction of BLDC Motor. The main design difference between a brushed and brushless motors is the replacement of mechanical commutator with an electric switch circuit ...
The motor you created uses direct current, or DC, to rotate the armature. The magnetic force is only able to flow in one direction, so the motor spins in only one direction. AC, or alternating current, uses the same principle of electron flow, but the pole is rotating rather than in one place.
