Abstract
PURPOSE: To increase the cooling air in a permanent magnet field type DC rotary machine by introducing the cooling air into air core of an air core interpole winding to flow axial air so as to reduce the air flow resistance.
CONSTITUTION: A permanent magnet field core 2 and an air core interpole winding 3 are mounted on the inner peripheral surface of a yoke 1 so that the axial length Li of the air core of the air core interpole winding is longer than the thickness La of the core of an armature 4 and the axial length Lp of the permanent magnet field core. After the cooling air introduced from an intake opening 14 of the yoke 1 is entered into the outer peripheral surface of a commutator by a fan 13 provided at the rotor, it is passed through the air gap of the outer periphery of the armature and simultaneously intaken from the portion a of the air core of the interpole winding longer than the axial length of the iron core of the armature 4 as designated by an arrow, then passed axially through the air core, flown toward the fan 13 from the air core b, and thus exhuasted from an exhaust opening 15.
