Wtf? How to open a Hacker motor?

Slottless stator, it will spin alot smoother than a slotted stator motor (neu, medusa).

Remove the screws from just the rear end, then tap the shaft against a hard surface, and the rear endbell will pop right off. By tap, I mean quite hard/firm- you may use a hammer to make life easier, just hold the motor firmly in your hand and hit the end of the shaft.
