I have several 3 phase 6 wire motors without nameplates from an industrial freezer. The supply voltage is 208. So I wired a couple motors in Delta for low voltage L1-T1-T6, L2-T2-T4, and L3-T3-T5 only to find the motors overheat and fail. The same thing happened when I tried wiring them in Wye L1-T1, L2-T2, L3-T3, and T4-T5-T6 over heat and fail. The only motor that works and was already on the freezer is wired L1-T4, L2-T5, L3-T6, and T1-T2-T3. This appears to be Wye wired backwards! How is this motor working when my other motors wired in Wye failed?
