To accurately calculate characteristics of a model of an electric motor or an electric generator in simulation.SOLUTION: A model characteristic calculation device 1 comprises: an iron loss calculation unit 24 that calculates an iron loss Wi of a model; an iron loss correction unit 28 that corrects the iron loss Wi to an iron loss Wi' so that the iron loss Wi calculated by the iron loss calculation unit 24 approaches an iron loss of an actual electric motor or generator; and a compensation unit 29 that performs at least one process of a powering compensation process that compensates characteristics of a loss incurred in the model during powering using the iron loss Wi' corrected by the iron loss correction unit 28, for the characteristics of the model during the powering, and a regeneration compensation process that compensates the characteristics of a loss incurred in the model during regeneration using the iron loss Wi' corrected by the iron loss correction unit 28, for the characteristics of the model during the regeneration.SELECTED DRAWING: Figure 2 【課題】シミュレーションにおいて電動機または発電機のモデルの特性を精度よく算出する。【解決手段】モデルの鉄損Ｗｉを算出する鉄損算出部２４と、鉄損算出部２４により算出される鉄損Ｗｉが実際の電動機または発電機の鉄損に近づくように鉄損Ｗｉを鉄損Ｗｉ´に補正する鉄損補正部２８と、力行時のモデルの特性に対して、鉄損補正部２８により補正される鉄損Ｗｉ´を用いて力行時にモデルに生じる損失分の特性を補償する力行補償処理、及び、回生時のモデルの特性に対して、鉄損補正部２８により補正される鉄損Ｗｉ´を用いて回生時にモデルに生じる損失分の特性を補償する回生補償処理のうちの少なくとも１つの処理を行う補償部２９とを備えてモデル特性算出装置１を構成する。【選択図】図２
