Abstract

PURPOSE: To discharge generated heat due to the lowering of a rotational speed, with a coupling member, by projecting the coupling member of a rotor outside windings wound up on stators.
CONSTITUTION: In a space between a plurality of rotor cores 2, 3, confronted with no plurality of stators 24, 25, a plurality of conductors 5 are respectively short-circuited via a coupling member, and the coupling member 42 is projected and set outside windings 22, 23 wound up on the stators 24, 25. As a result, in a low speed rotation range, ventilating cooling action is attenuated, and the resistance of the coupling member is heightened and heat is generated, but the coupling member is projected and set outside the windings wound up on the stators and so the generated heat of the coupling member is not transmitted to the stators, and heat can be discharged by the rotation of the coupling member itself, and efficiency can be prevented from being lowered due to the generated heat.
