PURPOSE:To support and fix an armature winding with an adequate strength and to reduce a distance between the armature winding and a field winding to acquire a high output by inserting an insulating tube into an inner peripheral surface of an insulating tees and by supporting and fixing the armature winding from an inner diameter side. CONSTITUTION:An insulating tees 2 is provided to an inner diameter side of a magnetic shield 1. An insulating tube 7 is inserted into an inner diameter side of the insulating tees 2 in an axial direction all over an entire length of the insulating tees. Therefore, an armature winding 4 is supported in a radius direction by the insulating tube 7. Since a supporting strength can be thereby improved, the insulating tube 7 is made thin. It is possible to allow the armature winding 4 to come near a field winding and to reduce field magnetomotive force. A larger output can be acquired by that amount if a configuration is the same as a conventional one. Manufacturing efficiency can be also improved. |
