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.
DC Motor Speed Control. There are three main ways to achieve speed regulation in series DC motors–flux control, voltage control, and armature resistance control. 1. Flux Control Method. In the flux control method, a rheostat (a type of variable resistor) is connected in series with the field windings. The purpose of this component is …

Construction and Working of Brushless DC Motors Electrical equipment often has at least one motor used to rotate or displace an object from its initial position. There are a variety of motor types available like induction motors, servomotors, DC motors (brushed and brushless), etc. to be used depending upon the application requirements.
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.

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.
The construction is same for DC motor and DC generator. Working of DC Machine The working principle and operation of a DC machine is based on an effect when a current carrying conductor coils laying in a magnetic field, the magnetic field produces a mechanical force on it known as torque which rotates the conductor coils in magnetic field.
The basic construction of a DC motor is shown in Figure 1. Standard DC motors are readily available in one of two main forms: Permanent magnet, where the magnetic flux in the motor is created by permanent magnets which have a curved face to create a constant air-gap to the conventional armature, located on the rotor.
A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. ... An alternative construction fits the outer races inside a metal tube, while the inner races are mounted on a shaft with a non-conductive section (e.g. two sleeves on an ...
Construction of brushed DC motors. Like most electric motors, a brush DC motor comprises two essential parts: the stator (or stationary part of the motor) and the rotor (or rotating part of the motor). The rotor typically features coils wound around an iron core and surrounded by magnets (contained in the stator, as shown in the Figure below. ...
Construction of DC Motor: Stator: The stator is the stationary part of the motor, consisting of a core made of laminated steel sheets. The stator core is designed with slots, which are wound with insulated copper wire to create a series of coils. These coils are connected in such a way that they form a magnetic field when a current flows ...
The construction of a DC shunt motor is similar to other types of DC motors, as shown in the figure. This motor can consist of basic parts such as field windings (stator), a commutator, and an …
In high-speed Construction and Working Principle of DC Motor, the segments are so shaped that they can be clamped by two cast-iron V-shaped rings as shown in Fig. 6.12 (b). Each commutator segment forms the junction between two armature coils ("finish" of one coil and "start" of the other). In large machines flat copper strips known as ...
Step 5: Make Iterations. Your motor will probably not work the first time, so you will have to constantly fiddle with the armature and the paper clips to make them line up and spin correctly. Problems that might make your motor not work are: The ends of the armature are not straight so it gets caught on the paper clips.
In commercial motors, an electromagnet is used in place of permanent magnet. large number of turns of coil is used. a soft iron core is used on which the coil is wound. Uses of Electric Motor:-It is used in electric fans, refrigerator, mp3 player, washing machine etc. DC motor consists of split rings while AC motor consists of two slip rings.
The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc generator can be run as a dc motor and vice-versa. In this article, we will explain the construction of dc machine in detail. Read: Working of DC Motor

Construction of AC Motors. Industrial applications frequently use AC induction motors. We'll discuss 3-phase, 460V AC, asynchronous induction motors. When the speed of the rotating magnetic field is more than the speed of the rotor, you know it's an asynchronous motor (see illustration). The AC motor consists of three basic parts: the ...

Electricity Basics. Electricity is the flow of electrons through a wire. When lots of electrons flow in the same direction we call this current. DC electricity means the electrons flow in just a single direction, from one terminal of a battery directly to the other. If we reverse the battery then the current will flow in the opposite direction.
