Abstract
The permanent magnet type electrical rotating machine has an overhung rotor support structure in which a shaft of a rotor is supported at only one end side thereof by a bearing provided on one side of a casing of the electrical rotating machine. Another end side of the rotor shaft to be a bearing support-free side is capable of being joined to an end of a shaft of a prime mover via a flange formed at an end of the shaft. The rotor shaft is configured such that, upon a state of not being coupled to the prime mover shaft, the flange on the bearing support-free side is joined to an end face of the casing through a retaining member to be prevented from moving in any of an axial, radial and circumferential directions of the rotor shaft.
