PURPOSE:To increase the cooling effect on coils, by inserting insulating diaphragms of molded sheets in waveform in the longitudinal direction into the whole length of coils along the edge coils. CONSTITUTION:In order to control the movement by the electromagnetic force of edge coils 2a projecting from a stator core 1, insulating diaphragms 4 is inserted along the edge coils 2a. The insulating diaphragms 4 is an FRP combined with epoxy resin with reinforced fibre with glass, carbon, boron, etc., as a base material which is molded in waveform in longitudinal direction, of which the height dimension of the waveform is molded larger than the gap dimension of an edge coil 3 interval. The insulating diaphragm 4 is compressed by being inserted into the edge coil 3 interval, with the counter force of which the edge coil 3 interval is firmly secured. The insulating diaphragm 4 inserted into the edge coil 3 interval is secured to the edge coil 2a bound with an insulating tight-fastening material 5 at the apex of waveform in contact with the edge coil 2a.
