ELECTRICAL MACHINE STATOR Russian patent published in 2005 - IPC

FIELD: electrical and electromechanical engineering; composite-frame stators of electrical machines.

SUBSTANCE: proposed electrical machine stator has laminated core 1 disposed inside cylindrical frame 2. Pressure pins 3 disposed at butt-ends of core contact hold-down members 4 enclosing end portions of winding 5 placed in slots of core 1. Stator is closed at ends with end shields 7. Each hold-down member 4 is secured on one end with stator frame 2 and on other end, with end shield 7. In this way stator components are reliably secured dispensing with pressure rings and bracing ribs.

EFFECT: reduced metal input, simplified design of stator and electrical machine as a whole.
