Abstract
Official abstract text for this publication.
A system (for controlling cooling of an alternator) comprises a control system, an alternator, and a blower fan, the alternator having a stator and a rotor. The control system is adapted to estimate one or more temperatures of the stator and/or rotor of the alternator using a thermal model. The control system is also adapted to control the blower fan to cool the alternator by providing a specified amount of air flow across the stator and rotor of the alternator, based on the estimated one or more temperatures of the stator and/or rotor.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system comprising: an alternator including a stator and a rotor; and a blower unit, comprising: a control system; and a blower fan integrated together with the control system to form the blower unit, wherein the blower unit is configured to estimate one or more temperatures of at least one of the stator or rotor of the alternator using a thermal model and to control the blower fan to cool the alternator by providing a specified amount of air flo…
