| description | PROBLEM TO BE SOLVED: To provide a temperature estimation device of a rotor of a dynamo-electric motor, which has a high general purpose.SOLUTION: In a temperature estimation device, an output torque Tthat is an actual torque of a dynamo-electric motor 1 that is operated in accordance with a driving signal (a three-phase current i, i, i) detected by six torques, is acquired, a torque calculation device 13 acquires: the driving signal (the three-phase current i, i, i); a position detection signal (a rotation angle θ) of the dynamo-electric motor 1, a d-axis inductance; q-axis inductance; and a calculation torque Tas a torque of the dynamo-electric motor 1 in a reference temperature calculated on the basis of a magnetic flux interlinked with a d-axis armature winding by a permanent magnet field in the reference temperature. Thus, a temperature of the dynamo-electric motor 1 is estimated on the basis of difference of the output torque Tand a calculation torque T.SELECTED DRAWING: Figure 1
