  • Patent number: 12112580
    Abstract: An interference margin between a stator and a rotor is measured after a rotary electric machine is manufactured, and the measured value is stored in a memory of a life predicting device as an allowable limit value. The life predicting device calculates a wear amount of a bearing portion of the rotary electric machine from an operation state amount of the rotary electric machine, and determines whether or not the rotary electric machine reaches an end of a life and maintenance is needed based on the calculated value and the allowable limit value stored in the memory.
