Abstract

A permanent magnet electrical rotating machine is provided which is capable of contributing to protected permanent magnets and increased cooling performance during operation. The permanent magnet electrical rotating machine includes: permanent magnets; rotor cores that have the permanent magnets mounted thereto and are laminated in a rotating axis direction; spacers that are placed between adjacent rotor cores; and permanent magnet protection members that are installed between the permanent magnets and the rotor cores and also placed to maintain radial continuity in space partitioned by the spacers between the rotor cores.
