Laminar stator core for rotating machine - has helical tube carrying coolant produced by centrifugal moulding process

摘要

The laminar stator packet, for a rotating machine with indirect liquid cooling, is cooled by a helical arrangement of tubes carrying coolant and fixed to the stator by centrifugal moulding. The backs of the laminar packet with pressure rings also serve as casting moulds and are connected to the stator hub. The backs of the laminar packet with pressure rings and a cylindrical pressure tube form a circular space that accommodates the cooling tube (5) and is filled with casting material. The casting material also connects with the hub and provides reinforcement.
