Re: Siemens motor numbers
Looks like the only difference is 1 = IP65 protection vs. 6 = IP68 protection. You new motor is better sealed, and will run underwater :) IP68 = Protected from total dust ingress. Protected from long term immersion up to a specified pressure. (1M)
see page 6/12

Re: Siemens motor numbers
Its been a long week. I knew I was missing something earlier. There is one other thing different in the 2 numbers. In the second string one is a 4AF71 and the other is a 1AF71. Im looking but havent found wat that designation dictates yet.
Re: Siemens motor numbers
See page 6/6 for the 1AF71. Looks like it might be a shaft length difference, I just had time for a quick glance. You need to study the specs a bit.
