Methods and systems for monitoring stator winding vibration |
摘要 |
<p>Embodiments of methods and systems for monitoring stator winding vibration of a rotating electric machine are provided. According to one example embodiment, a system (100) includes at least one sensor (102) including at least one conductive sensor antenna (122) deposited on a first side of at least one layer of a printed circuit board substrate (124) and positioned to substantially face a stator winding, and a non-conductive shield (126) mounted to an opposing side of the printed circuit board substrate (124) and positioned to substantially face away from the stator winding. The system (100) further includes an alternating current power source in communication with the sensor (102) and operable to deliver current to the conductive sensor antenna (122). A signal processing unit (130) may be in communication with the sensor (102), operable to measure a load on the sensor antenna (122) and to transmit vibration data to a controller (132) responsive to the load on the sensor antenna (122).</p> |
