Determination of the beginning and end of the motor winding

types of electric winding

The main types of electrical windings, which are often used, such:

1. method, which includes a special lamp.The point is that one end of the coil is attached to electric voltage, and the other to this lamp.When elektroobmotka produce electrical circuit, then the lamp is turned on.Certain conclusions note, and then decide where to start and where it ends.
2. transformed type.This method also includes a control lamp, you can use a multimeter, this lamp is attached to any one winding and all other ends include a network of about 220 volts.At that moment, when the initial phase ends connected to the other, there is a magnetic flux, which has its direction perpendicular to a completely different phase-thirds.
   
3. Method of picking up the ends.It is demanded when the engine is operated about 2-5 kW.The point is that the output of each winding connection to the same place for all point of the other fingers, respectively, are connected to another point.To the motor worked well, at a general point should be all the three pins.More precisely all the beginnings and ends (3 pieces).

   

definition of primary and secondary windings of the transformer installation

It so happens that the transformer plant on his body has absolutely no markings, but has copper cables that protrude from four terminals.One has a large brood of copper cable, and the other thin.A person who has already faced such a question would immediately sure what to do.Since the super-slim cord - is elektroobmotka primary type, respectively, the second string - secondary type.

One of the mandatory indication is that the primary winding is connected only to the mains voltage of 220 volts, and it is wrapped in a thin cord of a copper base.So, making a conclusion, we can say, the initial winding is performed with a thin wire, as well as the resistance of her 62 Ohm.Since secondary elektroobmotka filled with a thick cord, less resistance.Secondary elektroobmotka may include several turns, can not be said about the primary, it is always only one.
