ABSTRACT:
In an alternating current dynamoelectro machine, the rotor core and/or stator core are axially divided into a plurality of blocks, adjacent blocks of the rotor core and/or those of the stator core are fixed to the rotor shaft and to the motor frame, respectively, at different positions on circumference of respective blocks, whereby an interactive vibration energy between the blocks is absorbed by relative vibrations produced between the adjacent blocks so that vibrations and noises of the machine can be reduced.
