Abstract:
1. An apparatus for correcting the shape of an inner surface of a stator which is fixed inside an inner surface of a housing of a rotating electric machine, said apparatus comprising: a measuring device for measuring the shape of the inner surface of the stator fixed inside the inner surface of the housing of the rotating electric machine; a processing unit for calculating a direction of deformation and the amount of deformation of the shape of the stator inner surface based on the measured shape of the stator inner surface as well as a direction of heating and the amount of heat to be input when heating an outer side surface of the housing for correcting the shape of the stator inner surface based on the calculated direction and amount of deformation of the shape of the stator inner surface; and a heating device for heating the outer side surface of the housing based on the direction of heating and the amount of heat to be input calculated by said processing unit.
