Abstract

PURPOSE:To ease the surface pressure focused on the ends of contact by forming fine rugged parts on a contact surface bringing the wedged grooves formed on the periphery of a rotor member into contact with the buried member engaged in the grooves. CONSTITUTION:A lot of slots 3 are provided to a rotor core 2 which is formed together with an axis as a unit in an axial direction, and a coil 4 is inserted into the lower part of the inside of these slots 3. And, the arbitrary number of a wedge 5A is inserted into the coil 4 through a specer 6. And, a knurling tool-like fine groove 12 is provided to a contact surface bringing the wedge 5A into contact with the slots 3. According to the constitution, the surface pressure focused on the contact surface bringing the buried member formed by engagement into the wedged groove into contact with the wedge grooves can be eased, and a fretting damage caused by a bending flexure of the rotor can be prevented.
