Title:
AIR GAP WINDING TYPE ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPS58154360
Kind Code:
A
Abstract:
PURPOSE:To rigidly hold a stator coil to a circumferential direction by inserting an insulating key into an axial keyway formed on the inner periphery of a magnetic shield and a keyway formed on an insulating spacer arranged between the coils. CONSTITUTION:A plurality of stator coils 4 are disposed on the outer peripheral side of an insulating inner cylinder 3, an insulating spacer is filled between the coils 4, and an insulating retainer 5 is contacted with the outer periphery of the coil 4, thereby forming a coil assembly, which is disposed on the inner periphery of a magnetic shield 11, and fixing means for radially pressing the coil 4 such as a wedge 8 is provided between the shield 11 and the retainer 5. A plurality of axial keyways 11a are formed on the inner periphery of the shield 11, a keyway 12a is formed on the outer periphery of an insulating spacer 12 corresponding to the groove 11a, and an insulating key 13 is inserted between the keyways 11a and 12a.
