Motor Lead Connections?

[Besoeker]

Single hole compression lugs on each conductor with a single bolt with thermaly stable spring washers would provide you with the proper electrical connection.

I'd go along with that with a flat washer.
Lug, flat washer, spring washer, nut....

The Polaris Burndy style connections require an additional sleeve for use with the fine strands of motor leads. Torque wrench.
