A dynamo-electric machine is provided with a horizontally extending shaft (14), a rotor (15), bearings (13), a stator (12) which is provided with a stator core (16) having an opening (20) which is formed therein and which surrounds the outside of the rotor (15), and a frame (11) which supports the bearings (13) and the stator (12). The rotor (15) has a rotor core (21), permanent magnets (22) which are inserted in the rotor core (21), clampers (23, 24) which are arranged so as to axially clamp the rotor core (21), and a slide section (30) which is disposed on the front end clamper (23), protrudes further radially outward than both the front end clamper (23) and the rotor core (21), and consists of a material softer than that of the stator core (16). The easiness of work of inserting the rotor (15) into the stator (12) is improved, and the generation of metallic powder due to the collision between the rotor (15) and the stator core (16) is suppressed. |
