Abstract: A stator 1 for a rotary electric machine, comprises a ring-like yoke core 2, tooth portion cores 3 with teeth arranged at equal intervals on the inner peripheral side of the yoke core 2, stator coils 5 attached by inserting to each slot part 4 formed between the adjoining tooth portion cores 3 and a connecting part 3A small in sectional area for coupling the inner peripheral sides of the adjoining tooth portion cores 3 so as to electrostatically shield the portion between the stator 1 and the rotor 6, the rotor 6 being set opposite to the inner peripheral sides of the tooth portion cores 3 with a gap held therebetween. Thus, lowering axial voltage and preventing the development of electrolytic corrosion are made possible by cutting off electrostatic capacitance from the slot parts 4 to the rotor 6.
