But some motor have this serial MPL-B4540F / KK 24AA, some have this serial MPL-B4540F / SK 24AA. What is the difference between this type of motor. Are compatible ?Thanks [/INST] Welcome to the Forum ! I've attached a .pdf printout of the MPL motors Catalog number descriptions, taken from the Selection Guide, page 36... -KK24AA seems to me an incorrect catalog number, maybe -HK24AA? Hope this helps, - fuzzy logic \\n </s>
