Forward-Reverse Wye-Delta Motor Control Circuit...

[fherdzpowerhaus]

using four magnetic contactor for forward, reverse, delta and wye control, the unit is 60hp 440volts 60hz 1800rpm induction motor wye delta connection.

to all electrical practitioners please analyst this connection

line-1 (U-Z), line-2 (V-X), line-3 (W-Y) forward rotation

line-1 (U-Y), line-2 (V-Z), line-3 (W-X) reverse rotation

(U-X) winding one
(V-Y) winding two
(W-Z) winding three

could be possible this to use in the circuit? please send me your answers, suggestion, comment or illustration to me,attach file in my E-mail: fherdz26@gmail.com

this induction motor to use for mixer and crushing machines or (heavy equipment)machine.

thank you and more power to all members...

IMHO change only the 2 lines to reverse the rotation

[fherdzpowerhaus]

this is forward-reverse wye-delta control not forward-reverse only including wye-delta connection thats why four magnetic contactor are together in sequence..are you familiar in this control?

[kinyo]

line-1 (U-Z), line-2 (V-X), line-3 (W-Y)

line-1 (U-Y), line-2 (V-Z), line-3 (W-X)

afaik, the two configurations (both are delta) would result in the same direction of rotation

if you draw the delta wiring of the first configuration ... to arrive at the second configuration, you swap windings V-Y and W-Z, and then swap L2 and L3 ... effectively a double swapping of lines

[♪ ♫ ♫ ♪ ♪ ♪ ♫ ♫ ♫]

it is usually done like this....

for wye to delta switching....




for terminal switching and rotation reversal....








T's are terminal to be switched for delta to wye conversion (the curve lines are the motor windings), only two lines are swapped for reversal of rotation.

(U-X) winding one
(V-Y) winding two
(W-Z) winding three

Eto, Operation is forward reverse with wye delta starting method.

In forward rotation ganito ang connection:

@wye

L1 : U
L2 : V
L3 : W

XYZ : Tie together

Then after the set time on wye delta. the connection would be,

Forward Delta

L1 : U & Z
L2 : V & X
L3 : W & Y

This one is in reverse rotation same starting method:

@wye

L1 : V
L2 : W
L3 : U

XYZ : Tie together

Then at Delta connection

L1 : V & X
L2 : W & Y
L3 : U & Z

Ang alam ko pag ganitong crushing ang method eh meron pang sequence ang motor na ireverse nya automatic yung motor rotation pag maraming load na nakain yung crusher or pag di nya kayang icrush yung mga items. Then after ilang second eh mag forward ulit ang rotation to crush the items again. Operation repeat hanggang ma pulbos na yung item. Ang gamit nilang sensor eh current ct. Pag nag over current eh tiaka lang mag activate yung reverse rotation the mag start yung timer to forward the rotation...

BTW,

I think kaya ng apat na contactor yung requirement mo na reverse forward with wye delta starting. Antok na kasi ako kaya tinatamad na akong mag drawing dine.... Pagod sa work...

Isang contactor sa forward, isa sa reverse, at isa sa wye and delta. lagyan mo ng electrical and mechanical interlok yung forward and reverse contactor, Tapos mas ok kung meron din yung wye delta contactor for more safety. Sobra laki ng motor kaya dapat maraming safety installed sa magiging design. Yun laang muna... Tutulog muna ako...

Yong Delta to Wye bro, kaylan nya ito dapat e engage sa crushing operation?

Yong Delta to Wye bro, kaylan nya ito dapat e engage sa crushing operation?

Bale ganito ang sequence nung machine na sinasabi ko na parehas ng querry ng t.starter.

Forward wye then forward delta (continous running yan hanggat di nataas ang ampere eh tuloy ang crushing, once  nag high current at nalagpasan ang current setting nung sensor with a span of time set. Mag reverse yan ng reverse wye then reverse delta, then me timer yan for reverse after matapus countdown eh balik sa forward rotaion with wye delta ulit. Ganun lang operation. Di na yung delta to wye. Di ba kaya lang naman nagkaroon ng wye delta sa 60hp eh sobrang laki nung motor kaya ganun starting method nya. mas ok to kung sof start ang method para wala ng madaming contactor at timer..... hehehehe... Napakasimple, Less maintenance pa at tipid pa sa kuryente...

In Philippine Electrical Code the real answers are using four magnetic contactor to forward-reverse wye-delta motor control circuit, that means are reversable rotation of induction motor (clockwise and counter- clockwise) 10hp and above could be use the motor sequence in reversable rotation in this option, so four magnetic contactor are adviseable.
Each control are assign for this in Forward, Reverse, Wye and Delta...
this is not to save in highly maintenance or savings your money to provide each control because this is mandatory to use the four magnetic contactor in this motor control circuit...

Now, in this sequence the only problem is how will you tap the wiring in permanent connection, maybe all of you have answers for this and analysis about this wiring diagram and all of you are showing your optional answers that maybe correct or not but my question is, did you test this in experimental connection in your own opinion, have you experience this motor control in your work in industrial field, did you have encounter this in trouble shooting or installation in your company during your duty?..
I really appreciated all your opinion here in this analysis of forward-reverse wye-delta motor control circuit or power diagram, but you may a sure of your comment or suggestion to be practising as consultant or inspector if you have a doubt in your opinion, thank you to all and more power to all members...

Napakasimple nyang problema mo. Wala ka lang bilib sa sarili mo. Binibigay na sayo eh ayaw mu pang maniwala at duda ka pa. Tsk tsk tsk..... Yang connection mo eh isa laang sa mga ginawa, naranasan, nakita, natutunan, natroubleshoot at lahat na sa talambuhay ko bilang isang electrical and instrument tech. Ganito na laang, Kung nahihirapan ka sa design mo eh IUPA mu na. Yun laang...

Nga pala, isa pa, andyan si google. itype mu lang yung tanong mo.

Kung wala kang idea sa actual electrical connection eh mag aral ka muna ng basic. DIRECT ON LINE CONNECTION. Pag me sumabog eh ayun... malapit ka ng matuto..... PEACE!

what i really mean is, 3P 440V 60HP motor is worth around Php 1M, u really need Rockwell or Siemens or other tested motor controllers manufacturers and not e-lab to experiment your 1M asset.

the logic of your switcher is very simple but its not like that in the actual application, for one, i think u are aware that u will be switching at least 45kVA load.

i think all you want to know is given by Ahl****  more than that i think u need Rockwell or Siemens  

peace po tayo

Mahal sumingil mga yun ah. Hehehehe.....

i think he needs another million to put the motor in real application hehehehehe

[ahlburuto]

Correct.... Baka surplus yung motor... Hehehehe.... Peace....

ah ganon pala ang controls non, thanks!

[kinyo]

how will you tap the wiring in permanent connection

the wiring for reversal is not difficult, google it

the wiring for delta-wye changeover is a little tricky but here it is



needless to say, you would need to provide mechanical or electrical interlocks so that the relevant pair of contactors are never energized at the same time!
