Yeah, most krautrock sounds more like Can than Kraftwerk. Have you listened to Neu? They're another krautrock band worth checking out, formed by a couple of early members of Kraftwerk actually so that might interest you.
I love all three of those tracks as well, especially "Radioactivity".
As far as finding something similar within krautrock goes, that's hard to say, Kraftwerk have kind of a different style from the other bands that were lumped into that category. That said Ege Bamyası by Can is definitely worth a listen. The style is quite different from Kraftwerk, but it's a great introduction to krautrock.
