摘要： An alignment fixture includes a rotor fixture, a stator fixture and a sensor system which measures a rotational displacement therebetween. The fixture precisely measures rotation of a generator stator assembly away from a NULL position referenced by a unique reference spline on the rotor shaft. By providing an adjustable location of the stator assembly within the housing, the magnetic axes within each generator shall be aligned to a predetermined and controlled tolerance between the generator interface mounting pin and the reference spline on the rotor shaft. Once magnetically aligned, each generator is essentially a line replaceable unit which may be readily mounted to any input of a multi-generator gearbox assembly with the assurance that the magnetic alignment will be within a predetermined tolerance.

摘要： A motor driven assembly includes a motor having a motor shaft mounted for rotation about a rotational axis and a rotor radially located about the shaft. The motor drives a compressor that receives air from the motor, compresses the air, and circulates the compressed air to a space. The motor includes a first cooling flow passage and a second cooling flow passage that each receive air to provide internal cooling of the motor. A portion of the air compressed in the compressor is diverted from the compressor to a heat exchanger. The heat exchanger cools the compressed air from before the air circulates into the first cooling flow passage to cool the motor. The second cooling flow passage receives air from the environment surrounding the motor driven assembly to further cool the motor.
