Bosch drum 'jolt'

[adamthemieleman]

Hi all, I wonder if someone can give me an answer, as curiosity is getting the better of me.

Today at work, I was just looking at a few machines, and armed the drum of a Bosch. I noticed that the drum just abruptly stopped, it didn't coast down like the others. I tried it on other Bosch machines, and it only seems to happen on the Ecosilence drive. Can anyone shed any light on this, I'm assuming it must be something to do with the motor?
