All About Motors

Motors are designed to convert electrical energy supplied to them from the power source into mechanical energy. This type of more types are depending force is used to provide power to move and operate machines in industries and robot control panels. The primary interaction that takes place in a motor to bring about this conversion is from the magnetic field of the engine and the winding current.

The Major Parts of a motor.

A motor has various parts that help it to achieve its purpose and just as discussed above these elements take part in this magnetic field and winding current interactions.

· Rotor: This is the rotating part of the motor, and it moves the shaft to create the mechanical power. It is primarily fitted with power conductors to carry electrical currents, which acts on the magnetic field in the motor to bring about the force that rotates the shaft.

· Stator: This is the unmovable inner lining part that is electromagnetically charged and is laminated with metallic plates to prevent energy from being lost. The stator is fitted with either winding or fixed magnets.

· Bearings: These aid the rotation of the rotor and to avoid friction by facilitating the smooth complete 360-degree rotation of the rotor. They are contained within the outer motor casing; hence the shaft goes through them to the exterior end of the motor which carries out its functions

· The air gap: This is the space between the rotor and the stator; this distance is of great essence in that it dictates the efficiency and the power consumption of the motor. This space is required to be small to increase the magnetization force and not too little to create friction and noise.

· Windings: These are the lamination sheets that wrap the magnetic core. They can be of varying make depending on the manufacturer’s preferences such as aluminum coils or copper.

There are two main types of motor, and those are the brought about by their kind of power supply, that is, the DC motors an AC motors. DC stands for Direct current while AC stands for Alternating Current. Under these two major classes, there are more types depending on their features and how they operate.


The primary concern when buying a motor is always its efficiency and cost of its operation. Therefore, a thorough study is of the essence before purchase and also there is need to familiarize with ways of maintaining them.
