Title:
STATOR FIXING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2014/046101
Kind Code:
A1
Abstract:
A stator fixing structure is configured such that a projection (2) is provided to project from the outer periphery of a stator (1), which is formed by stacking a plurality of plate-shaped members, in a radial direction while a fastening member (11) is inserted into a fastening member inserting hole (3) formed in the projection (2) so as to fix the stator (1) to a frame (8), and the outer peripheral surface of the stator (1) except the projection (2) is fixed to the inner peripheral surface of the frame (8) by shrink fitting. A dent (4) is formed at the root of the projection (2), thereby reducing the proportion of the projection (2) in the periphery of the stator and increasing the contact area between the frame (8) and the stator (1) for the shrink fit part (7). Thus, the stator (1) can be effectively fastened to the frame (8).
