Electrical motors construction

Electric motors are used in many applications and industries. They are used in electric cars, elevators, fans, pumps, and many other devices. The construction of an electric motor can be done using the rotor, bearings, stator, air gap, windings, commutator, etc. The rotor is the moving part of the motor and its main function is to rotate the shaft for generating mechanical power. The stator is the fixed part of the motor and it consists of laminations of silicon steel. The stator has two electrical components: magnets set and an armature. One of them is attached to the stator and the other to the rotor, together making a magnetic circuit.

Electric motors rely on principles of magnetism. A coil of wire carrying a current in a magnetic field experiences a force that tends to make it rotate. This effect can be used to make an electric motor. Most often, copper windings are powered by an electric current, generating a magnetic field. This interacts with a separate magnetic field – often created by an array of permanent magnets. The interaction between the two fields causes the rotor to turn.

Electrical motors

Electrical motors convert electrical energy into mechanical energy by using electromagnetic phenomena. They are used in a wide range of applications such as electric vehicles, industrial machinery, household appliances, and more.

There are several types of electric motors such as AC motors, DC motors, stepper motors, and more. Each type has its own advantages and disadvantages depending on the application.

Electric motors convert electrical energy to rotational mechanical energy by using electromagnets with currents to create force. The basic principle underlying the functioning of an electrical motor is Faraday’s Law of induction, which states that a force is created when an alternating current interacts with a changing magnetic field¹. 

There are mainly three types of electric motor: DC Motor, Induction Motor, and Synchronous Motor. All of these motors work with more or less the same principle, which depends upon the interaction of magnetic field with current¹. 

electrical voltage

Electric potential difference, also known as voltage, is the external work needed to bring a charge from one location to another location in an electric field. Electric potential difference is the change of potential energy experienced by a test charge that has a value of.

Medium voltage is a class of nominal system voltages that is higher than 1,000 V and lower than 100 kV. It is commonly used for subtransmission, primary distribution, and industrial motors. The range of medium voltage may vary from 600 V to 69 kV depending on the equipment ratings and standards.

An increasing amount of low carbon technologies (LCT) such as solar photovoltaic, wind turbines and electric vehicles are being connected at medium and low voltage levels to electric power networks.

electrical current

Electric current is the movement of electric charge carriers such as electrons having negative charge, protons having positive charge, ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles) ². The intensity of electric current is usually measured in amperes.

Electric current is used in many practical applications such as charging batteries, operating household appliances like bread toasters, baking ovens, televisions and mobile phones¹. It also plays an important role in industries, transportation and communication.

electrical switchboards

An electrical switchboard is a piece of equipment that distributes electric power from one or more sources of supply to several smaller load circuits. It is an assembly of one or more panels, each of which contains switching devices for the protection and control of circuits fed from the switchboard². 

Switchboards are used to safely distribute electricity throughout commercial and industrial facilities. A switchboard is a component of an electrical distribution system which divides an electrical power feed into branch circuits while providing a protective circuit breaker or fuse for each circuit in a common enclosure
