A 12 lead motor is common for dual voltage, wye delta starting. The nameplate diagram is what I would normally expect to see expect for the low voltage delta connection. Your diagram depicts the higher voltage delta connection. While unusual, I think you have to use what’s on the nameplate unless you can get some other verification from the supplier.
So first, make up the 12 leads in the motor peckerhead to the "High" part of the top diagram. then take the 6 leads to the starter and connect them to the terminals as shown in the lower diagram. If your starter has "T1,2,3 and 4,5,6" instead, then U1 = T1, V1 = T2, W1 = T3, U2 = T4, V2 = T5, W2 = T6.
I have a motor currently wired for 240 that I’m trying to convert to 480. I have 2 hours to get this job done. I’m stuck on this motor— the wiring doesn’t match to diagram. I’ve never seen this before anyone have any ideas? See pictures. Sent from my iPhone using Tapatalk
For a 12 lead motor there are four potential configurations: Low voltage delta Low voltage wye High voltage wye High voltage delta What's the operational difference between high voltage wye and high voltage delta?
The rest of the notes from that project, switching 12) wye delta motors from low volt to high volt and changing the overload relays to suit. Take special note of the second drawing, where it says to swap the winding connections, when using the wye delta control, otherwise the motor will change...
The above paragraph was stated in a manual for a 12 lead dual voltage motor. The motor was first wired up as a wye. The vfd would fault for phase lost. Could you explain to me why wiring the motor as a wye would cause the vfd to trip for phase loss? Just curious.
SO say i have a 3 phase system supplied bye 277 480v wye utility. the 12 lead motor diagram shows that it can be hooked up wye start (10,11,12) (4,7) (5,8) (6,9) (t1,l1) (t2,) (l2 t3,l3) high voltage, or in Delta start (L1,1,12) (L2, 2,10) (L3,3,11) (4,7) (5,8) (6,9) Can I use either diagram or do i need to hook it up as wye start since the feeders supplying the motor are 277 480v wye? In my ...
The plant I work at has WYE 480V 3 phase. Just got in a rebuilt motor back. Its a 12 lead motor. I didnt unwire it. From what I am reading online it should be 4&7, 5&8, 6&9, 10&12&11 wired together. Then my line voltage to T1, T2 and T3. It will be running on a VFD. Let me know...
Two speed motors can have 12 leads brought out. Anyway the real fun comes in when some of the lead markings get lost. The main thing here is to look at your motor speed, horsepower and amp ratings and wiring diagram before you do your connections. NEMA MG 1 2003 Part 2 pages 27 thru 33 show these standard conections.
We have a 12 lead motor with the namplate listed as 440 480V. It lists 440 480V and then is followed by wye delta. How should this motor be wired? We are thinking in delta with the windings in parallel? Where does 440V come from? Is this a common voltage somewhere?
