1-phase AC generator
1 phase generator is a generator that can generate voltage 1 phase so it only has a single generator stator coil only.
Part of this generator consists of

     The generator stator is not rotating
     The generator rotor is moving.

Construction syinchon generator can be distinguished:

     Outer pole generator, usually fixed while the magnetic coil is the formation of GGL moving parts / spinning.
     Poles in the generator, the generator is part of the magnet is moving / rotating coil while the formation of GGL is the part that does not move.

Judging from the type of reinforcement, the generator's magnetic currents can be divided into

     Generator amplifier (self exited)
     Generators separate amplifier (Exinted separately).

Motor 1 phase G = 24, P = 4 Half coil
Type - the type of AC motor can both be distinguished
1 Motor series
2 Motor Shaded pole
3 Motor Repulse
4. Motor universal
5. Run capacitors
6 Star capacitor
Motor star sentifugal capacitors usually have a switch, the switch that serves to break the auxiliary coil (auxilary winding) if the motor is spinning 75% of the normal rotation, so that the motor is working only primary coil alone (main winding).
To reverse the direction of motor rotation can be done by reversing the direction of the current in the coil auxiliary or primary coil, with the proviso that the motor should stop rotating ... first.
Motor 1 phase G = 24, P = 4 full (Whole) coil
Type - the type of motor capacitors
1 Run capacitors
2 Star capacitor
3 Doble capacitor
This capacitor motor rotation (n) is very certain, that be affected by:
1 The number of magnetic poles (p)
2 The frequency electric (f)
So: n = 120 X f / p (rpm)
For wrapped around the stator we must know
1 Number of poles (P)
2 The number of grooves (G)
3 Width of the coil (which)
4 The number of grooves per pole per phase (q)
So: yg = G / P
Seen from the electric motor windings are divided into 2
1 coil consentris (centered)
2 coil distribution (spread)
Type the stator windings are divided into
1 Whole coil type (full) coil
2 Half coil winding type
Motor 3 phase G = 36 P = 6 Whole (full) coil
Based on the shape of the head liaison between the sides of the coil, the stator can be distinguished
1 Barrel type is typically used coil winding coils impinge / spread (winding distri plugs)
2 Spiral coil motor type is centered (consentrin)
Based on the comparison of the groups by the number of pole magnet coils are used, the stator can be distinguished
1 coil windings half (half coil winding) is the coil group half when more number of pole - pole magnet.
2 full coil windings (whole coil winding) the coil when the group is equal to the number of poles - magnetic poles.
Based on the distance between the magnetic poles, the stator windings can be distinguished
Step 1 (full pitch) when the minister to move the sides of the coil windings in the coil group is equal to 180 electrical degrees. Y = π
Step 2 short (fracti - pitch) when the coil step hand-side coil on coil lebil a small group of 180 electrical degrees. Y <π
Motor 3 phase G = 24, P = 4 half coil consentris
For generatot or wrapped around the stator motor stator, we must consider several factors, among others:
a. Number of phase (m)
b. The number of grooves (G)
c. Number of poles (P)
So that G = P.m.q
q = number of grooves perkutub each phase
3-phase motors G = 24, P = 4 full coil consentris
3-phase motors rotation is influenced by the frequency factor (f), the number of magnetic poles, the motor proficiency level on the terminal there is a notation: UVW; XYZ and can be connected in star (Setar) Y or delta (Δ)
3-phase motors which can be converted into a speed of 2 to 4 speed is called "motor Dahlander" change as the change of magnetic poles.

Step work roll electric motor
There are electric motors 1 & 3 phase.
There are two kinds of coils, namely: Concentric and Spiral. To improve the electric motor or generator and the like, the steps are as follows:
In the first image (For beginners) plot, plan and list of full winding coil or half coil and first calculated the number of windings ... original.
Prespan (Paper plastics which are used to coat the wire with the email body in the groove)
Prespan paper or mica to coat Email coil (coil) adjusted to its original diameter.
Measure the width of the stator coils and make the mall
Mal: The diameter of the circle on the coil.
Sirlak: To coat the coil which is mounted on the motor so that if there are scratches on the email can be covered.
Install the coil / wire in the groove email - groove that has rolled from the main coil former.
After all the coils mounted on the groove, must be in advance meger. To know that there is a coil that is connected to the body
After installing the coil should be in the first meger. Useful to check if the coil is not leaking.
Can also use the ohm meter to determine the custody of each coil, the resistance between the coil can substitute Meger if do not have ...
Meger: Giving the AC power by using the tool (Tool) on a swivel so that electric currents produce up to 1000 Volts. So it should be 2 to avoid contact with the flow of electricity were.
When finished wrapped around the stator, coil gauge and the results are good we try to electrical voltage.
