Abstract

PURPOSE: To make an assembling operation of a magnetic pole of a revolving body and a magnetic pole piece easy by making each independent pole piece as one solid cylindrical body connected mutually with a non-magnetic material.
CONSTITUTION: Disposing a magnetic pole piece 13 at an external side of a magnetic pole 12, each magnetic pole piece 13 is formed annularly as one body connected through a non-magnetic material 14 between adjacent magnetic pole 13. An annular magnetic pole piece 13, for example grooves 15 are provided on a cylindrical magnetic body, after forming a cylinder by filling this groove 15 with a welding of non- magnetic body, by cutting both ends B portion it is formed. Following to this, after inserting a field winding 10 on a magnetic pole 12, a cylindrical magnetic pole piece 13 is either heat inserted or pressed in at an outside of a magnetic pole 12 to form and a field winding 10 is fastened in this manner.
