Abstract

PURPOSE:To obtain constantly stable vibration preventive characteristics in a rotary electric machine by arranging a cooler at a connecting member disposed between a bearing bracket and a base and thereby suppressing the temperature rise at the member, thereby alleviating the excessive compressing force applied to the spring member. CONSTITUTION:The cooler 12 and a heater 11 are mounted at a stay 3 interposed between the bearing bracket and the base 10. Furhter, a displacement detector 13 is mounted at a spring member 6 or the like to detect the displacement of the spring member 6. If the displacement is large, cooling water is introduced into the cooler 12, thereby suppressing the thermal elongation of the stay 3. If the displacement is, on the contray, excessively small, the heater 11 is operated so that the compressing force applied to the member 6 may become constant. Thus, constantly stable vibration preventive characteistics can be obtained, and the lifetime of the member 6 can be prolonged.
