An electric current motor where a twisting force is built by the response, between changing magnetic field produced in the generator, and the current flows to the coils of the rotor coil. These three-phase motors are used for the applications in agriculture and have some essential parts. Such as:
Frame: the frame of the engine keeps all pieces together in place and gives a mode of attaching the motor to the machine. The framework also helps in conducting the heat produced within the motor and get rid of the heat faster; some structures have fins too.
Stator: It is an overlaid engaging centre which puts together the electrical windings which flow and produce a magnetic field.
Rotor: it has no windings, but it helps in turning. The rotor pole expands from one side of the motor to make a connection to the device or machine.
Bearings: they help in holding the moving pole to the motor frame, and they come with different types that are roller, ball bearings, and sleeves. It depends upon the organizing position and implementation of the motor to choose the bearings.

Three-phase Motor Types
There are three types of motors commonly used:
Induction motor: it is primarily used in agriculture because its speed is constant but differs depending on the weight.
Synchronous motor: it runs at a continual speed nevertheless of the load on the engine. It usually has a rotor coil and is commonly applied in the electric clock or timer.
Direct-current motor: it is used mostly in vehicles or engines where variable speed is needed.
Advantages of the Three-phase motor
The way electric energy flows and the construction of the engine gives many benefits listed below.
Low cost: they are low in price because of their modest design. Therefore, these three-phase motors are preferred in industrial implementations and for home and business applications. Since they are simple in the look, thus, they require low maintenance cost.
Speed variation: its speed is almost constant and moves only in a varying by a few percents. Another benefit of the three-phase motor is that it is durable for a long time which makes it ideal for use and for that reason, the motors run for many years with no cost and maintenance.
