PURPOSE:To provide a simple salient-pole type rotor and to improve the reliability of the rotor by engaging a pole supporting pin with a circular recess which is formed on the bottom of a dovetail groove, and supporting the pole by a restricting member in which the notched part of a pole supporting pin head is contacted with the projecting end of a pole end plate. CONSTITUTION:A dovetail groove is formed on a yoke 1, a dovetail projection 2a is formed on a pole core 2, the projection 2a is engaged with the dovetail groove, and a tapered cotter 4 is hitted therebetween, thereby coupling the core 2 with the yoke 1. Further, a circular recess 9 is formed on the bottom of the dovetail groove of the yoke 1, a pole supporting pin 10 is engaged to contact the head notch of the pin 10 with the projection 2a. On the other hand, the end face of the cotter 4 is formed with the same plane as the end face of the yoke 1, thereby making contact with a cotter retainer ring 5. |
