Classification: CPC G | IPC G

Claim 6:
7. An insulation resistance estimating device configured to estimate a ground insulation resistance of a servomotor, comprising:
a processor;
a memory having instructions stored thereon, which when executed by the processor, cause the insulation resistance estimating device to:
store a learning model that has been generated by acquiring multiple pieces of training data and executing a supervised learning using the training data, wherein each piece of the training data includes the insulation resistance of the servomotor at a beginning of a certain period, time-series data indicating a condition of the servomotor in the certain period, and the insulation resistance of the servomotor at an end of the certain period;
acquire the insulation resistance of the servomotor at a beginning of another certain period that is different from the certain period;
estimate time-series data indicating the condition of the servomotor in the another certain period; and
output the insulation resistance of the servomotor at an end of the another certain period, using the stored learning model, and in accordance with the acquired insulation resistance of the servomotor at the beginning of the another certain period and the time-series data indicating the condition of the servomotor in the another certain period.
