Abstract
A motor temperature estimation system includes a first temperature time series data generation unit that generates first temperature time series data based on temperature data acquired by a temperature sensor that measures a temperature of a motor, a resistance value time series data generation unit that generates resistance value time series data based on the first temperature time series data, a second temperature time series data generation unit that generates second temperature time series data by changing parameters for estimating and calculating the temperature of the motor based on the resistance value time series data, and a parameter determination unit that determines the parameters by comparing the first temperature time series data and the second temperature time series data.
