A Starter is a device that controls the use of electrical power to equipment, usually a motor. As the name implies, starters "start" motors. They can also stop them, reverse them, and protect them. Starters are made from two building blocks, Contactors and Overload Protection.
You will build a simple electric motor, called a Beakman's motor. You will change the strength, as well as the configuration, of the permanent magnet and study its effect on your motor. You will change the strength, as well as the configuration, of the permanent magnet and study its effect on your motor.
Electric Motor : A labelled diagram of an electric motor has been shown in following. Principle : A currentcarrying conductor, when placed in a magnetic field, experiences a force. If the direction of the field and that of the current are mutually perpendicular then force acting on the conductor will be perpendicular to both and will be given by Fleming's lefthand rule.
Sep 22, 2014· The working of a DC motor is well explained in this video with the help of animation. Construction details of DC Motor, Shunt Series motor, concept of back EMF are also explained in this video.
• The motor is controlled by applying a voltage to the motor leads. The higher the voltage, the higher the speed. The direction is changed by reversing the polarity on the leads. • The maximum torque is limited by the current rating of the motor and it is obtained at zero speed (startup).

An electric motor is a device that turns electrical energy into motion, usually rotation. It changes electrical energy into mechanical energy or kinetic energy (kinetic energy means movement).

The basic principle behind working of a transformer is the phenomenon of mutual induction between two windings linked by common magnetic flux. The figure at right shows the simplest form of a transformer. Basically a transformer consists of two inductive coils; primary winding and secondary winding.
An AC Motor converts electric energy into mechanical energy. An AC Motor uses alternating current in other words, the direction of current flow changes periodically. In the case of common AC that is used throughout most of the United States, the current flow changes direction 120 times every second.
An induction motor or asynchronous motor is an AC motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic .
Electric motor WikipediaAn electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this is the conversion of mechanical energy into electrical energy and is done by an electric generator, which has much in common with a motor.
In this motor, the stator is of multipolar and its construction is similar to that of variable reluctance stepper motor as discussed above. It consists of slotted periphery on which stator coils are wound.
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 commutator is a moving part of a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. Function of commutator changes as per the DC machine.
This is a basic 3pole DC motor, with 2 brushes and three commutator contacts. The use of an iron core armature (as in the Mabuchi, above) is quite common, and has a number of advantages 2 .
