PROBLEM TO BE SOLVED: To solve a problem that a gap is formed between a motor case and a stator of a motor fixed by interference shrink fit by a temperature rise and vibration during the operation of a fluid machine and that the rattle of the stator, vibration and noise are generated by getting the stator unable to be fixed on the motor case. SOLUTION: The stator 9 is prevented from falling by fastening and fixing the stator 9 of the motor indirectly on the motor case 111 by fitting it in an iron ring 11 having a thermal expansion coefficient equivalent to or smaller than that of an electromagnetic steel plate.
