6 FAQs about [Generator stator wind deflector installation]

Can air deflector reduce stator winding temperature rise?

The above analysis proves the potential and effectiveness of the air deflector in reducing the stator winding temperature rise. In addition, there is no contact between the proposed structure and the primary components of the motor. Therefore, the electromagnetic performance of the motor is not affected.

Does air deflector installation affect stator winding hotspot temperature rise?

In the following, the impacts of air deflector installation on the stator winding hotspot temperature rise are analyzed by comparing the global temperature characteristics of the motor without and with the air deflector.

How to reduce temperature rise in a stator winding?

To date, there has been much technical literature on stator winding temperature rise suppression. The proposed methods can be broadly summarized into three categories: novel windings, introducing heat dissipation reinforcement structures in slots, and enhancing cooling of the end winding.

Does a stator winding change the temperature distribution?

Both the temperature distribution of the axial section as well as the stator winding show that the stator end winding temperature at the air outlet side drops significantly after installing the air deflector, and the overall temperature distribution of the stator winding is improved.

Where are high voltage stator windings made?

in Beloeil, Quebec, Canada) where the high voltage stator windings continue to be manufactured. The insulation systems ha e been maintained, only the names have changed to HV600 (High Voltage) and LV400 (Low Voltage). The design, manufacture and installation of the stator wi

What is the minimum clearance between air deflector & stator end winding?

Moreover, to ensure that the designed air deflector can be used in practice, a clearance of at least 5 mm is maintained between the air deflector and the stator end winding (i.e., the maximum value Hr can take is H -5). In addition, the thickness of the air deflector is 3 mm. Fig. 7. Position and geometric parameters for improvement study.
