The machine you're talking about isn't indicated. However, when the motor is locked it is trying to run the needle and feed dogs at the same time that it is trying to wind the bobbin. This cannot be done simultaneously.
*** The place where you place the bobbin must be set firmly against the bobbin.
***Some newer digital systems still need the hand wheel to be released by hand. (Turn it, push or pull it)
