Wiring of Reverse Forward Motor Starter

This video demonstrates how to make "Reverse Forward Motor Starter". This video covers both power wiring and control wiring along with testing at the end of video using motor run status. We have used 3-phase supply from the VFD output set at low frequency so that motor rotates slowly to check the direction of rotation. Hope this video serves both tutorial value along with practical approach.
We hope this video will be helpful to beginners, technicians and students who are new to automation and electrical systems.

U a one of my best lecturer's. Imple clear and precise. Wonderfully explained . Thumbs up

[@saidkhalfan3785]

Bro you are the best ever . thank you so much my brother .

[@c-jaygabriel9874]

These videos are very productive,they teach me alot as a technician/power engineer.

[@starautomation]

Thanks

[@josefaschwanden1502]

Id advise you rather to go to school than learning from this vid, already the first wire was faulty and a fire hazard.

[@sly_fox8261]

Awesome Explanation man! Very easy to understand and thanks for the visual explanation

[@anandchidmalwad6264]

Thank you sir

thank you sir good explaination

[@Ak-lt8zy]

Very helpful. .Thanks

[@mythril4]

This video is older but one small thing, use motor reverse contractors. They have a bar inside them that crosses between contractor preventing both from ever being active at the same time creating a 3 phase short.

[@conraddebeer1662]

Thank you

[@TechTricks786]

Good job 👍

[@shravanyadav395]

Very halful video sir 🙏🙏

[@SaiKumar-wk4mk]

Sometimes a possibility of stuck the contactor due to mechanical problems. In this method no interlock is provided to avoid phase to phase short circuit in such case. Add one NC contact and take coil supply through it, ie the supply to F is in series with the NC of R and vice versa.

[@starautomation]

Yes. NC contact of Rev Contactor in series with Fwd Contactor coil and similarly NC contact of Fwd contactor in series with Rev Contactor coil is required for electrical interlock.

[@SaiKumar-wk4mk]

@@starautomation One more disadvantage is there. No protection is provided for the motor. Two expensive contactors are used. An overload relay and 3 push button is required for this. I think the conventional circuit is better than this.

[@MediaBangladesh94]

very so nice

[@RAHULSHARMA-cv2kk]

Can the same be used for 3-phase linear induction motor?

[@dilipram1329]

NICE VIDEO SIR, R.B.PRADHAN CHENNAI (TAMIL NADU)

[@starautomation]

Thanks

[@umeereshu]

Sir u r not gave a input connection in l1,l2,l3 but that connected to output side (reversed) & a1 gave to neutral instead of phase..

[@mardiasultanamoni6060]

nice

[@mumgurung3577]

Nice video,per aap hindi me video banaao to achha hoga . Schneider contactor or 14pin wala really,push button lagaake reverse forward stater control connection wearing video dekhado please.

[@ojiralam1233]

Good joop sir

[@noelphiri1722]

Nice one

[@muhammedafsal7806]

Can i use no nc terminal contact instead of cam switch

[@alfredibidapo6640]

How can I use DTDP toggle switch to connect the contactor instead of selector you have used.Thanks

[@moviedekho8244]

How connected rotary switch supply

[@sombdr2032]

Please sir more information

[@jocelynbruces3898]

i try to understand the way you discuss soo far it is ok...but next time you blog...you should put label on it every wire end and put a motor control wiring diagram...

[@nafeeskhan-kd6ws]

Very nice sar mujhko penal ki or jankari .

[@SB-vv1uh]

Nice video, I just wanted to know which motor you use i just want same setup and bought everything which you showed in this video only motor have to choose..please guide

[@starautomation]

Motor should be 3-phase induction motor. Motor current rating should be less than contactor current rating.
Suppose motor current rating is 3 Amps. Then for Direct online starting, contactor current capacity should be 6 times. So, 6x3 = 18A.
So select contactor of 18A or 25A current rating.

[@jayathissavitharana4053]

1 is connect to pase suply. but you don't show it us

[@abasjabr7573]

please this connection for single or 3phase motor nice video

[@starautomation]

for 3-phase motors only

[@milanprvulovic2544]

What's this black wires connect a switch?

[@V3_one]

Sir u r super
clear cut video
and
But i have a one another doubt that is
Q: what is small connetors imean i saw on contactor small aditional connectors what is the use

[@starautomation]

Contactor do have Normally open contact and normally closed contacts, also called as NO and NC contacts.
When contactor is switched On, NO contact gets shorted and NC contact gets open circuit.
These contacts are used in control wiring.

[@naveenkumar9025]

You took phase for switch point 1.. and you took neutral from A1 point of both contactor.. it is clear.. and what you did the long wire of contactor..

[@microsalesservices9295]

Please video banao hume jarurt padti hai useke connection kaise hote hai

[@manojbisht2002]

Sir pl 4 moter ready one by one star connector connection and three phase thanks

[@gurupowersystems4441]

very nice please termination crimping the luges praperli

[@starautomation]

Of course. We should use proper lugs along with crimping tools to fix it.

[@darmintoaji3159]

Di tambah pakai timer bang, biar jalan bolak balik sendiri🙏🙏

[@gordhardmkisi9243]

How the contecter works

[@ermiastaye3095]

I shall something to do

[@vijaykansal6804]

👍

[@nileshthosar6907]

V nice

[@starautomation]

Thanks

[@heesir9762]

My starter motor only one wire how to make forward n reverse can you send me diagram showing

[@dineshpatil3249]

Mast banaya hai Lekin hindi mai banao

[@skyways5165]

Sir apne selector switch ka 1terminal kha connection kiya

[@dnyaneshwarkale6724]

Automatic limit switch use reverse forward motor

[@ajaydeep9765]

interlocking krna jaruri tha bro... agr contector chipk geya toh three phase flash mare ga.

[@starautomation]

You are right but the MCB used at input supply will take care of short circuit protection

[@faddifaddi2261]

phase nikala kaha say liya main cable say nikal gaya a1 say , R F mi lag gayi tar magr 1 or 2 point smj ni aya q kay cam wrong direction mi tha

[@electricgyancentre3722]

All electrical panel knowledge hindi 👉 electric gyan center

[@jamalhussain6487]

I don't know where you contact the selector switch wire 1

[@jamalhussain6487]

Jo aap bolty Hy k ye phase sy connect Hy mager Kedar

[@rabinrahulmohanty4255]

Sir diagram ke sath video karenge Tao Acha hota plz sir

[@dattarajdevalkar1794]

plz provide names of the components used in this circuit

[@subhajitsubho5999]

Please attach drawing along with this.

[@mandipkamboj1484]

Overload relay?

[@JoseLopez-sz5zj]

Easy is just change the line

[@sandeepdakhara3776]

Singal phase motor reverse forward kese kare

[@hotcoke648]

Where is the "point 1 for the switch" connected to?

[@attiqrehman8989]

To any live phase out put of main contactor

[@microsalesservices9295]

SIR only rotory switch used a reverse and forword

[@starautomation]

Sure.

[@Engineer.VijayDubey]

Not compulsory.you can use add on blocks N.O. point to coil supply.

[@sivatech9876]

Sir without contactor me reseve nahi hoga.. reply me

[@starautomation]

To change rotation of motor, we need to change phase sequence.
Both contractors have opposite phase sequence.
Other way of doing this will be to use Variable frequency drive. In this case, Contactors will not be required.
