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 in the market, including induction motors, servomotors, DC motors (brushed and brushless), etc. Depending upon the application requirements, a particular motor can be selected.
PowerPoint Presentation : Therefore if a conductor lies within a magnetic field: motion of the conductor produces an electric current an electric current in the conductor will generate motion The reciprocal nature of this relationship means that, for example, the DC generator above will function as a DC motor although machines designed as ...
DC Motors 5 enough so that the force created by the magnetic field (F = Bil) equals the load force applied on the shaft.Then the system moves at constant velocity. 4.3.4 Torque Developed The equation for torque developed in a DC motor can be derived as follows.

Electric motors are a device driven by the magnetic force which transforms electric into mechanical energy.
Motor Nameplate Information-The Service Factor on a Motor Nameplate Indicates How Much Above the Nameplate Rating a Motor Can Be Continuously Loaded. -Example: 40hp 1.15sf Is Good for 46hp Continuously -The Motor Nameplate Will also Provide Key Application Information to Include: Full Load
The same DC machine can be used as a motor or generator. Therefore, theoretically, construction of a DC motor is same as that of a DC generator. Working principle of a DC motor An electric motor is an electrical machine which converts electrical energy into mechanical energy. The basic working principle of a DC motor is: "whenever a current carrying conductor is placed in a magnetic field, it ...
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. BLDC motors are superior to brushed DC motors in many ways, such as ability to operate at high speeds, high efficiency, and better heat dissipation.
Construction of a DC machine: Note: A DC generator can be used as a DC motor without any constructional changes and vice versa is also possible. Thus, a DC generator or a DC motor can be broadly termed as a DC machine. These basic constructional details are also valid for the construction of a DC motor. Hence, let's call this point as ...
Types of DC Motor A Direct Current Motor, DC is named according to the connection of the field winding with the armature.Mainly there are two types of DC Motors. First, one is Separately Excited DC Motor and Self-excited DC Motor. The self-excited motors are further classified as Shunt wound or shunt motor, Series wound or series motor and Compound wound or compound motor.
Construction of Three Phase Induction Motor: Figure 8.1 shows the construction of three phase induction motor.A 3 phase induction motor has two main parts (i) stator and (ii) rotor.The rotor is separated from the stator by a small air-gap which ranges from 0.4 mm to 4 mm, depending on the power of the motor.
Construction of dc Machines: The rotor in a dc machine is called an armature. The armature has cylindrical steel core that is composed of a stack of slotted laminations. Slots in laminations are aligned axially along rotor or shaft. Armature windings are placed in slots. The stator in a dc machine is the field part of the machine.
Check out this animation Back to The Motor A simple motor has 6 parts: Armature or rotor Commutator Brushes Axle Field magnet DC power supply Armature, Commutator and Brushes The armature takes the place of the nail in an electric motor. The armature is an electromagnet made by coiling thin wire around two or more poles of a metal core.
A DC motor is an electrical machine which converts electrical energy into mechanical energy. The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given by Fleming's Left-hand Rule and its […]
A servo motor is an electrical device which can push or rotate an object with great precision. If you want to rotate and object at some specific angles or distance, then you use servo motor. It is just made up of simple motor which run through servo mechanism.

DC series motor works on the direct current converting electrical energy to mechanical energy. It works on the principle of generation of rotational motion when a conductor placed in magnetic field carries current. The interaction of the generated magnetic field and external magnetic field results in the rotational movement. In this motor field winding is placed in series to the armature.
The shunt DC motor has the field winding in parallel with the armature (Fig. 1).In a parallel circuit, the magnitude of voltage drop across each parallel element is the same, while the magnitude of current through each parallel branch is a function of the impedance of the element.
Series DC motor. In a series DC motor the field is connected in series with the armature.The field is wound with a few turns of large wire because it must carry the full armature current. A characteristic of series motors is the motor develops a large amount of starting torque. However, speed varies widely between no load and full load.
Difference Between AC and DC Motor The AC Motor and the DC Motor are differentiated on the various factors like the source or the nature of the power used in the motor. The commutation process, types, starting of the motor, a number of terminals. Applications of the motor, usage of brushes and the maintenance cost of the motor.
