Hi, thanks for sharing this video. I think, power cable for Reverse , those two phase cable "RED AND YELLOW" should be exchanged at R main contactor input end, rather than output end. otherwise, when take reverse action, delta side, cables cannot be exchanged. it will bring short cuit risk.
The power wiring is right. They won't short circuit because in the control wiring (Which is in another video I suppose) you'd have the forward and reverse contactors interlocked to each other by tying the a1 of each contactor to the 1NC of the other contactor (In the exact same manner as you'd interlock the star and delta contactors to solve basically the same issue.). You could also do it the way you said on the input side, it would be doing the exact same thing, but you'd still have to interlock the F and R contactors...othewise, without the interlocks, you'd short.

In this connection, coil u1 and u2 get yellow phase when reverse contactor energise. For resolving the issue need to make phase change(R and Y) on reverse contactor input side instead of output side.
Animation achha hai bhai. Per ye practicality work nahi hoga. Q ki jab reverse me jayge to ek winding ka potential difference zero ho jayega.. Is ke liye Delta ka reverse contactor bhi chahiye..
I’m a residential electrician and would love to learn motor controls. Do you have something available for a beginner and a place I could order parts from?
An all round Electrician is hard to find , We have our own speciality of what we are good at , Me Im happy fault finding in Industrial Machinery of all types , and keeping up with wiring regulations in Domestic housing can be a challenge for me .
No need for two overload relays, the load for U1 V1 and W1 will be the same as the current in U2, V2 and W2 unless in case of a short circuit, and in that case the circuitbreaker is the protection.
Power feed to the Fwd and Rev Contactors comes off the motor terminals , ?, All power Feeds should be fed off and linked from the top side of all 5 main Contactors , One of the Fwd and Rev Contactors will need to be energize before the motor can be started in Star Delta .
What was he thinking wiring in an extra , Overload unit , and feeding the 3 phase supply to the Fwd and Rev Contactors off the motor connections , Red to Red and Blew to Bits comes to mind !!!
Delta contactor incoming connection is wrong, just swipe L1 to L2 in Delta contactor incoming side contacts. Else u will get R-phase at U1 and Y-phase at W2, this may burn motor. No matter in what direction u are running motor, motor terminal should have(U1W2- R-phase, V1U2-Y-phase, W1V2-Bphase), for other direction motor terminal should have(U1W2- Y-phase, V1U2-R-phase, W1V2-Bphase), hope u understood. Other connection is ok

This circuit is wrong. Phase reversal should be taken before reverse contractor so that in reverse condition, both side of winding will get phase reversed. In this circuit, Yellow phase will be connected to both end of U winding and winding V and W are in parallel with phase R and B connected across. Please correct the drawing. Thanks.
