Types of electromotor coils
Types of electromotor coils are used in different conditions and different types of electric motors have their own coils. The basis of electromotors is based on the magnetic field, and the coils are responsible for the production of the magnetic field needed to operate the engine, so it is very important to be familiar with the types of coils in the electric motors for people working in the field.
Here are a brief explanation of the coils of all types of single -phase engines so you can know what type of coil is used in.
Two phase design coils: two phase design:
These single -phase engines have a permanent launch coil, and the coil coils are in the form of half the grooves for the coil of the launch coil and the other half the grooves are assigned to the main coil. These two coils have a 90 -degree electric phase difference.
The steps to perform this type of coil are: "Coil calculations, preparation of coil table, drawing diagram and coil map, coiling and coil map". Gave.
Coil Frameflice:
: If in a coil, the phase difference between the beginning and the end of a coil is less than 180 degrees, it is called a fractional step.
In this type of coil, the electrical driving force that is inside the coil's arms will be compiled, and you should consider the result of the coil. The engine driving force will reduce, which will reduce the final power of the engine. To make up for this, it is used to enhance the number of motor coils and shorten steps.
Coil Full Step:
If at the end and at the end of a coil of 180 degrees of electric phase, as well as the forces in the arms of each coil to be algebraic, not vector, we are facing a full step.
Single -phase induction motor coil with permanent capacitor launch:
The capacitors used to launch the engine are up to 200 microfas. The reason is that the capacitor remains in the circuit after the engine is launched, helping to create a phase difference in the electric motor coil.
Permanent Auxiliary coil in a fractional step circuit:
Coils at the stator level is that to determine the position of the coils in the motor shell grooves we must consider being an individual or individual Q.
coil motors with a permanent coil in the structure of the three -phase engines, except that the coils are two -phase. The rotating magnetic field will cause the motor to move.
A variety of heads in electric motors
Single -phase motor with capacitance
Single -phase electromotor with capacitor is one of the most common ways. In this method, the launch capacitor is set in series with auxiliary coil. The way the single -phase electromotor with the capacitor should be such that the appropriate phase difference between the main and the auxiliary coil is
Three -phase single -phase motor
In the three -phase single -phase single -phase engine, there is usually a common wire and two wires for the main and auxiliary coils. This type of leader enables the rotation of the engine circulation.
The difference between the coil of the generator and the electromotor
The coil of the generator is different from the electromotor. In the coil of the generator, the target is the voltage production, while in the electromotor the target is the production of torque. The single -phase generator coil map and the three -phase generator coil map are designed for this purpose.
