T2–White . The Delta connected motor has a … DELTA CONNECTION We will need: 1- Ohm Meter 2- 6 or 12 volt battery 3- Tape to label leads 4- Copy of Augie Hand's "Identifying Unmarked Leads" First thing is to use Ohm meter, there are 3 separate pairs, to find the 3 different groups. 69.1 KB Views: 47. Usually six terminals from the three phases of an induction motor are available. The 3 phase AC source line voltage L1 is connected to the motor terminals 1-12, line voltage L2 is connected to the motor terminals 2-10 and finally line voltage L3 is connected to the motor terminals 3-11, while also individually joining together motor terminals 4-7 then 5-8 and finally 6-9 respectively (refer to above drawing). Identifying unmarked 12 lead wire motor Home. In order to identify the positive and negative leads of an unknown volt meter a simple test must be performed. Forums. It makes a difference what type of six lead motor it is as the way of identifying them are different. the rotor may be positioned so that one winding is at the maximum voltage and the rotor left in that position until the companion winding is located and connected. The motor should be assembled. When a downscale deflection of the voltmeter needle. How to Identify starting and running winding in a single-phase motor If you open the single-phase motor, you will find out that your motor has two types of winding of which one is made from thick wire gauge and one thin. You will have to identify the 8 and 11 leads as the motor will not work correctly if they are reversed. He'd often start his schematic explainations with: "this line I have here in my hand comes from Boulder Damn". Consequent pole, part winding, dual wound, wye-delta, etc. Proceed with the step 7 for rest of the coils and identify 3 groups of coils. Shift the battery to the #8 & #9 pair, with the positive battery lead on the #8 lead and the negative used for the flashing. This article will address lead identification of three-phase motors with 9 leads, based on the premise that none of the leads are marked. The rotor is needed to complete the magnetic path. 8. With the dahlander winding, it is only possible to reach a pole number ratio of for example 2:4, 4:8 or 6:12. A lead Wye Start/Delta Run Motor has the ability to meet several starting Wye Delta Starter or by a series of contactors in a control circuit.
