" From the daily dialogue with our customers, we have noticed specific needs to improve the features of the polar expansions of the stack. We have thought about the union of 2 solutions that were already separately wide tested: welding and gluing. We have promptly worked and developed DDLock for offering more solutions that can improve the performance concretely. "
Technical Dept
July 2021
" We have realized that a part of an already developed solution could be the right way to avoid a recurring defect on stator stacks: the spoke sensitivity of the extremities laminations. So we have adapted and developed this new system and invented different new solutions that have been afterward tested and implemented. "
Production Dept
September 2021
" We noticed since the first samples that DDLock guarantees excellent outcomes. We daily manipulate such stacks so we immediately realized that this solution is perfect to get unprecedented compactness, thanks to the hold of the stacks extremities. "
