Abstract
Apparatus features a signal processor configured to receive signaling from a flux sensor containing information about a residual field from an electrical supply to a motor of a driven machine and a magnetic field from one or more rotating magnets placed on a rotating component of the driven machine; and determine corresponding signaling containing information about the operation of the driven machine, based upon a difference between an electrical supply frequency and a slip frequency determined from the signaling received and processed. The signal processor also provides the corresponding signaling for further processing to determine further information about the operation of the machine.
