Fluid-passage built-in type electric rotating machine
First Claim
1. A fluid-passage built-in type electrical rotating machine, which comprises:
- a rotor fixed to a rotating shaft by means of a bearing;
a stator in rotating relation to the rotor with a gap between the rotor and the stator;
a housing surrounding the stator;
a pump turbine, fixed to one end of the rotating shaft, for circulating or transporting fluid in the electrical rotating machine;
a primary end bracket fixed to one end of the housing; and
a secondary end bracket fixed to the other end of the housing;
wherein the primary end bracket has a suction port for suctioning fluid into the electrical rotating machine, and the secondary end bracket has a discharging port for discharging fluid from the electrical rotating machine, wherein the outer periphery of the stator and the inner face of the housing confines a first fluid flow passage extending along the axis of the rotating shaft, one end of the stator iron core and the primary end bracket facing the one end of the stator confines a second fluid flow passage and the other end of the stator and the secondary end bracket confines a third fluid flow passage, and wherein the suction port, the first fluid flow passage, the second fluid flow passage, the third fluid flow passage and the discharging port are communicated.

Abstract
A fluid-passage built-in type electrical rotating machine, which comprises a rotor fixed to a rotating shaft by means of a bearing; a stator in rotating relation to the rotor with a gap therebetween; a housing surrounding the stator; a pump turbine, fixed to one end of the rotating shaft, for circulating fluid in the electrical rotating machine; a first end bracket fixed to one end of the housing; and a second end bracket fixed to the other end of the housing. The first end bracket has a suction port for suctioning fluid into the electrical rotating machine, and the second end bracket has a discharging port for discharging fluid from the electrical rotating machine. The outer periphery of the stator and the inner face of the housing confines a first fluid flow passage extending along the axis of the rotating shaft, one end of the stator iron core and the first end bracket facing the one end of the stator confines a second fluid flow passage and the other end of the stator and the second end bracket confines a third fluid flow passage.
