System and method for actively monitoring an air gap in a wind turbine brake assembly

A system and method are configured to monitor changes associated with an air gap in a brake assembly of a wind turbine yaw drive by: (1) receiving one or more sensor signals from one or more sensors that are indicative of changes associated with the air gap; and (2) comparing the changes associated...

Beschreibung
Zusammenfassung:	A system and method are configured to monitor changes associated with an air gap in a brake assembly of a wind turbine yaw drive by: (1) receiving one or more sensor signals from one or more sensors that are indicative of changes associated with the air gap; and (2) comparing the changes associated with the air gap to certain thresholds to determine if the air gap is in need of attention. The system includes at least one proximity sensor arranged adjacent to the air gap, to monitor the air gap, and a controller. The controller is configured to receive the sensor signal(s) indicative of the changes associated with the air gap. The controller also is configured to compare the changes associated with the air gap to one or more air gap thresholds, and to implement a control action based on this comparison.
