Mastering Wye-Delta Wiring: Step-by-Step Guide for 6-, 9-, and 12-Lead Motors! 🎯🔧

Very good video, clearly spoken and no BS.

[@D.Hozzie]

Just great stuff. We still have plenty of 1986 mcc’s and several RVAT motor starters. If you could make time to go over the RVAT with “ controls” …..that would be awesome. Thanks-IndyZooDude

How would you go about changing the rotation of open transition wye delta (480v)

Great video

Ive wired up so many motors. I have it memorized for 9-12 pole motors. High and low voltage. I've ran across some part winding start screw compressors before. They were oldies, but still chugging along. A few wye-delta's as well We use Polaris connectors on every motor above 5hp...peckerheads are small on less than 5hp.

Where is your video on the part winding control's

[@manuellastrollo2168]

Sir want to see your control circuit of 12 leads

[@thead9]

I think you have the numbering wrong on the last section(22:12). T7 and T4 should not be wired together in this configuration. It should be T7&T6 then T8&T4, then T9&T5. Otherwise you are swapping your coils around. Just like how you have it in the beginning of the video for 2M. In other words in the end through the contactor T1&T7&T6&T12 should be connected to L1. Then T2&T8&T4&T110 should be connected to L2. T3&T9&T5&T111 should be connected to L3 for a full hard start.

This is true for certain motors, but varies by manufacturers.

[@thead9]

@@MechanicalPros you contradict yourself with the motor you are using. That's why I said that. Look at the numbering

Very cheap and poor presentation
