It seems the link provided refers to 9 and 12 lead motors.
What I have is a six lead motor with wires that were originally
attached to terminals u1 v1 w1 and u2 v2 w2. This is for running
in a wye low rpm or delta high rpm configuration, i think.
The motor seems to have been rewound, and the wires relabeled
1,2,3,4,5, and 6. The original connection diagram shows connecting W2, U2, and V2 together along with connecting L1 to U1, L2 to V1 and L3 to W1 for the wye connection.
For delta, it says connect L1 to U1 and W2, L2 to V1 and U2, L3 to W1 and V2.
