摘要： PURPOSE:To reduce the abrasion of the coil insulating layer of a stator coil due to thermal expansion or contraction, by forming slot liners with the two layers of a coil side slot liner on the stator coil side and a core side slot liner on the stator core side. CONSTITUTION:A stator is provided with a stator core 1, a stator coil 2 inserted into the slot of the stator core 1, slot liners 3a inserted between the stator core 1 and the stator coil 2, and the like. The slot liners 3a are formed with the two layers of a coil side slot linear 3a1 on the stator coil 2 side and a core side slot liner 3a2 on the stator core 1 side. Slots 9 are arranged on the wall surface of the coil side slot liner 3a1, and the wall surface is treated with lubricant 10. As a result, the abrasion of the coil insulating layer of the stator coil due to thermal expansion or contraction is reduced.

摘要： PURPOSE:To prevent a layer insulator from notching at cutting by providing a field coil face supporting surface in a cooling fan. CONSTITUTION:A field pole 1 is formed of a core 2 and a pole piece 3 for preventing a field coil 4 from removing due to a centrifugal force. The coil 4 is formed of a winding turn 4a and a winding turn 4b with a cooling fan in a structure for forming the winding with the fin at several turns of the wind ing. The winding portion 7 to become a bonding surface with a field coil supporting device is provided at the winding turn 4b, and the cutting surface is spaced at an interval Aw from the turn 4a. Thus, since it can prevent a layer insulator from notching at cutting, the insulator can be held preferably in molding.
摘要翻译：目的：通过在冷却风扇中设置场线圈面支撑表面，防止层间绝缘体在切割时产生切口。构成：场极1由铁芯2和极片3形成，用于防止励磁线圈4由于离心力而移除。线圈4由绕组匝4a和绕组匝4b形成，该绕组匝4b具有冷却风扇，该结构用于在几匝绕组中与翅片形成绕组。在绕组匝4b处设置成为具有励磁线圈支撑装置的接合面的绕线部分7，并且切割面与转弯4a间隔开。因此，由于能够防止层间绝缘体在切断时发生切口，所以绝缘体优选保持成型。

摘要： PURPOSE:To prevent an isolating space from dropping by providing a chevron- shaped groove to become a radial vertex at the axial center on the bonding surface of the spacer of a coil supporting plate. CONSTITUTION:A field pole 1 of a salient-pole rotor has a field core 2, and a field coil 4 mounted through an insulating collar 3 on the core 2, and pole pieces 5 are provided on the core 2. A coil supporting plate 7 and an isolating spacer 8 impregnated with adhesive are provided between the coils 4 of the poles 1 arranged at the prescribed interval on an annular yoke 6 in the circumferential direction, and a chevron-shaped groove 9 to become a radial vertex is provided at the axial center on the bonding surface of the spacer 8 to the plate 7. Thus, the spacer 8 is engaged with the plate 7 in the groove 9, thereby preventing the spacer 8 from dropping.

摘要： PURPOSE:To satisfy good adhesion between a winding conductor and a pole iron core and to prevent the slip of a field coil by forming a field iron core with a dent at the angular part of the barrel section wherein an insulating layer and a winding conductor are wound on the barrel section for adhesion and fixing. CONSTITUTION:A dent 8 is provided at the angular part on the external circumference of the barrel section of a pole iron core 2 by applying bevelling so that the central part may have a maximum diameter of R1. An insulating layer 3 is wound on the barrel section of the iron core along the dent 8 and a winding conductor 1 applied adhesive is also wound. In this way, the adhered area of the pole iron core 2 and the winding conductor 1 increases and the winding conductor is engaged at the dent 8. Therefore, the slip-out of the field coil can be prevented.
