    Abstract: In summary the invention relates to method and apparatus for estimating electromagnetic forces active in an electric ma- chine. The method comprises the steps of: Measuring (S1) at least one first operation parameter (Y tot ) of the electric machine (20) while the electric machine (20) is operated under at least one operational condition, and Estimating (S2) electromagnetic forces (F tot ) active in an electric machine (20) during operation of the electric ma- chine (20) by multiplying the measured at least one first op- eration parameter (Y tot ) and a respective second operation pa- rameter provided by a stored structural/vibro-acoustic model (M). Due to the present invention, electromagnetic forces within an electric machine, in particular in the air gaps between the stator and rotor of the electric machine can be measured and disturbing noises and/or vibration resulting from the electromagnetic forces can be identified as well as eliminated.

    Abstract: A rotational element monitoring process (700) utilizing a machine condition indicating sensor and monitoring device (100) adapted to a rotating machine (410). The process (700) monitors at least one operating characteristic of a rotating element of a rotating machine. The operating characteristics can include velocity (500), acceleration (500), temperature (600), etc. The process (700) establishes a baseline value (524, 624) for each operating characteristic. An alarm threshold (530, 630) is determined by either a predetermined percentage difference (540) or a predetermined quantified delta (640). The device establishes a measurement schedule (740) retaining the device in a sleep mode (740) and pulsing a condition investigation in accordance with a frequency. The frequency increases (742) when approaching or exceeding an alarm condition. The device (100) indicates an alarm condition by illuminating an alarm indicating light (220, 222, 224).

    Abstract: Turbocharger operational condition is monitored using vibration and temperature sensors to project probable bearing failure. Baseline or nominal vibration levels and heat generation are established under conditions when bearing condition can be taken with confidence to be close to nominal. Departure in operating temperature and vibration at a threshold level from baseline operational condition is taken as an indication of probable failure.

    Abstract: In this system an unbalancing force, as set by an unbalance load injection device (42) integrated into a work piece balancing machine (10) and its balance computer (60), is injected into an injection plane (IP) through an operating portion of the machine (10). This injected load is in effect transferred by computation to a calibrating plane of a known standard or a masterwork part loaded into and rotatably driven by the balancing machine (10). The values of the unbalancing force as generated by the unbalance injecting device (42) and by calculation into the rotating master are sensed by synchronizer and vibration pick-ups (62). Data reflective of the injected imbalance are furnished to the balance computer (60) for the calibration thereof. The principle of this self-calibration is to use a workpiece drive spindle (16) and unbalance injector device (42) to inject a predetermined load at a known angle into the master to effect master unbalance. This induced unbalance is picked up by synchronizer units (62) and used as the parameters in the calibration process of the balance compute. This allows the machine (10) to accurately determining the imbalance in other work pieces (12). Subsequently conventional unbalanced work parts processed by the calibrated machine can be balanced by the machine with a higher-level of accuracy in accordance with balancing data of the calibrated balance computer.
