How to connect the electric motor the triangle?
To switch electric motor windings from "star" to "triangle" - business not it and difficult. But let's consider one more interesting moment. All electric motors of factory execution have 6 ends (conclusions) and to switch windings to other tension of works big does not make. And engines which have only 3 conclusions meet, that is "star" is hidden in the scheme of unsoldering of windings and is inside. With 3 conclusions electric motors generally come from rewind.
We will also be engaged in this question, we will remove 3 wires which are not getting to us.
The first, we disassemble completely the electric motor. After dismantling we overturn the stator the scheme to top and we knife the bandage.
We do everything accurately not to cut what be the wire and not to damage isolation.
All pieces of the knitting tape or twine are farther we delete. The winding was impregnated with varnish and the tape was pasted, here it accurately all should be taken. It is possible to use tweezers, it is possible combination pliers. Undermine so that not to damage the winding wire. If there are tape pieces in the slot between the winding and the body of the stator, then let remain and if from the inside where there will be the rotor, then it is necessary to remove under the root, differently it clings to the rotor, making the sound.
When the knitting tape is removed, we undermine junctions of coils. All of them are double, that is 2 wires connect and isolated, tubules (cambrics) most often put on, and can be simply isolated by the insulating tape. But among the coupled connections one will be from 3 wires, it also is the star. I will a little recede back when the tape was removed, look attentively , maybe, at this star, you will see at once and then it will not be necessary to disturb all winding. In my case it was necessary to raise almost all connections moreover the engine was in rewind, and the master very honestly prolachit it, hardly were undermined.
Further we disunite these 3 wires, and we solder the conclusion to everyone section such, as in barn. We stretch new conclusions in barn, accurately we stack them on the winding and again into place we coordinate everything. It is possible on old paths. For coordination we do the needle of the copper wire, with a section of 0.5-0.8 mm, we insert thread, it is possible kapron, and "we sew". When everything is coordinated, it is desirable to miss the mark all our work with varnish, it is better oil. It is simple to paint with the brush in order that the disturbed wires did not move to the operating time. After varnish dried, we assemble the electric motor.
Now let's understand that at us turned out. Conclusions which we had in barn we will mark C1, C2, C3, the tester, the sampler or ring-up found the second end - C1 and mark it with C4, C2 - its second end C5, and the remained wire we mark C6. Now we connect our tips in the following order (C1+C6), (C2+C4), (C3+C5). Here also we switched windings according to the scheme to the triangle. As you can see, everything is simple.Top
