Introduction of Electric Motor

In this report, there is comprehensive information on the electric motor. In the first part of the report, there is information about an electric motor. Then after this, there is complete information about how to build the electric motor with steps. Then after this in the last part of the report there is complete information about the operation of electric motor and how each part of the motor works.

Aim of the project of Electric Motor

The main aim of this project is to find out how magnets and electricity are working together in an electric motor.

What is an electric motor?

It is a machine that is involved in converting electrical energy in the form of valuable mechanical energy. The main purpose of this motor is to provide efficient mechanical energy that can be used for industrial use. There is about two types of power sources are used for its operation. The first one is DC supply and the next one is the AC supply. These motors may be categorized according to the power source type, application, internal construction and type for output motion.  It can be noted that these motors are involved in producing a rotatory force that is done through the use of magnets. These magnets are allowing the coil to move in a rotatory condition and due to this the electrical energy is converted in mechanical (Austin Hughes, 2013).

Step for building an electric motor

To make a simple electric motor contain quite simple steps. Through following these steps it will become extremely easy to make a simple electric motor at your home.

The first step is to find out the material and tools that are required to create a motor. These tools include pliers, pair of scissors, wire cutters, tape, and a glue gun. On the other hand, some materials include paper clips, magnets wooden blocks, DC wires and a battery.

In the next step, there is a need to create a copper coil. For that case, take a roll of copper wire and then after this cut the length of wire for about 2 feet through wire cutters. Now starting winding the copper coil and make it tighter. Moreover, leave some of the lengths of the wire from both ends and also strip the wires from both ends (Hughes, 2005).

In the next step, there is a need to sand both ends of the copper coil. Due to sanding, it will become simple to remove any part that will create hurdle during operation. After sanding both ends of the copper wire will become smooth.

In the next step, there is a need to build a rig that will hold the copper wire. This can be done through the help of a paper clip. For that case, there is a need to organize clips in such a way that they will hang like a proper rig for the copper wire. Then after this at the end of these clips attach two wires with the help of soldering. Both of these wire will be connected to a battery. Moreover, all of these adjustments will be done on a wooden block.

The next step is related to the attaching of the magnet. This magnet will be attached with the help of a glue gun. This step needs complete concentration. This is because if you don't place a magnet at the right place then the motor will not work properly. For that case, just mount the magnet in the middle of these two paper clips with the help of a glue gun.

In the next step, there is a need to make a proper platform for an electric source. For this take a wooden block and mount a battery on it through the help of a hot glue gun. Moreover, properly connect both wires with the battery through soldering (Herman, 2009).

Now after this put the copper coil on the paper clip rig and make sure that this coil is balanced and exposed ends are touching paper clips. Then check the connection properly with the battery. Then turn it on and it can be seen that the copper coil starts rotating. Moreover, if the copper coil is not spinning then it means it’s both ends are not properly sanded. Furthermore, make some adjustment for balancing this coil after this the motor will work properly.

How the motor operates and function of its different parts

The motor operates when an electric power source is applied from the input and through this the coil present in it will rotate through the help of magnets and mechanical energy is produced.

There are different parts of an electric motor that includes a power source, field magnet, and commutator, Armature, coil, brushes, and Armature core. All of these parts are extremely important for a motor (Herman, 2009).

Power source: there are about two types of power sources are used in a motor. The main purpose of the power source is to supply the power to the armature of the motor and its field coils.

Field magnet: This magnet is involved in producing a torque on the rotating armature coil through the phenomenon of Fleming's left-hand rule.

Commutator: It is known as the rotating interface of the coil that contains a complete circuit.

Brushes: This is a device that is involved in the conduction of current between the moving and stationary part like in the rotating shaft.

Armature core: it is involved in holding the armature coil and also providing efficient mechanical support.

Armature coil: it is involved in helping the motor to run with a smooth phase.

Conclusion of Electric Motor

Summing up all the discussion from above, it is concluded that electric motors are just converting the electrical energy into mechanical. In this report, there is brief information about the electric motors. It can be noted that there are two main types of these motors, the first one is DC and the other one is AC motor. Moreover, how to make a simple DC motor is explained with some important steps. In the end, there is complete information about the working of different parts of the motor in detail (Tong, 2014).
