ABSTRACT:
A device for assembling a stator formed by a stack of core laminations and windings on to a respective head support includes thrust members for clamping the stack between the thrust members and coplanar surfaces on the support. A centering device is provided which can be interposed between a shaft mounted in the support and the stack. The stack is traversed by a plurality of peripheral bolts situated in correspondence with the coplanar surfaces and are perpendicular to the coplanar surfaces and which are screwed into the support. The thrust members clamp the stack to the support with clamping forces at least substantially equal to the tightening forces to be applied by the bolts on the stack.
