Patent ID: 8812254

Claim:
A system for monitoring a stator winding, comprising: at least one sensor comprising: at least one actively powered conductive sensor antenna deposited on a first side of at least one layer of a printed circuit board substrate, wherein at least a portion of the at least one antenna is positioned to substantially face a stator winding, and a non-conductive shield mounted to an opposing side of the at least one layer of the printed circuit board substrate, wherein at least a portion of the shield is positioned to substantially face away from the stator winding; at least one alternating current power source in communication with the at least one sensor and operable to deliver current to the at least one sensor antenna; and at least one signal processing unit in communication with the at least one sensor and operable to measure a load on the at least one sensor antenna and transmit vibration data to a controller responsive to the load on the at least one sensor antenna.
