PURPOSE:To rigidly fix a stator coil by hitting a wedge into a gap formed between axial engaging prjections formed on the inner periphery of a magnetic shield and engaging projections formed on an insulating spacer formed between stator coil. CONSTITUTION:An axial engaging projections 1a are formed on the inner periphery of a magnetic shield formed in a cylindrical shape, a stator coil 4 is disposed on the outer peripheral side of an insulating cylinder, an insulating spacer 11 is provided between the coils 4, and an insulating retainer 5 is provided on the outer peripheral side of the coil 4. Fixing means for radially pressing the coil 4 such as a tapered wedge 9 split in thicknesswise direction is provided between the inner periphery of the shield 1 and the outer periphery of the retainer 5, engaging projections 11a opposed via a circumferential gap from the projections 1a are formed on the spacer 11 corresponding to the projection 1a of the shield 1, and a wedge 12 is axially hitted into the gap. |
