What will happen when I use an AL lug to terminate a AL cable to a motor with CU terminals?

What is the solution if any melting occurs at the terminals?

When Al lug is connected to copper termination, electrical corrosion and loosenes of termination starts due to, two dissimilar metal connected will cause circulating current and irregular thermal expansion.
SOLUTION:
*If copper termination part is TIN PLATED then there is no problem.
*If it is bare copper then we have to keep bimetallic strip between Al lug and Copper termination.
* We can use bimetallic / Tin plated copper lug for Al cable.
