A monitor attaches to a mount proximate a machine to determine the health operating history and operating status of the machine. The monitor is preferably self-contained, having its own internal power source, electronics, and sensor suite. If desired, the monitor may be powered by an external power source. One or more internal sensors disposed in the monitor are provided to sense machine operating parameters such as temperature, flux, and vibration. External sensors tethered to the monitor may be positioned at varying points on and/or in the machine. Monitor electronics process sensor outputs to determine machine operating parameters such as machine speed and load. Monitor electronics are also operable to transform time domain data generated by the sensors to frequency domain data. A communications port enables a peripheral device, such as a notebook computer or a computer network, to communicate with the monitor and download stored data. Downloaded data can be further analyzed and statistically compared with trend data at a base computer to further ascertain the health and condition of the machine. |

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS In accordance with a preferred embodiment of the present invention shown in FIG.
1, a motor monitor 100 capable of sensing, analyzing, storing, and outputting various motor operating data is attached externally to the frame 104 of a large industrial electrical machine, such as an ac induction motor 102.
Alternately, the monitor 100 may be attached to an ac generator for sensing and recording various life history parameters of the generator.
The monitor 100, which is fully self-contained in sensors, data acquisition, and power, is small in comparison to the size of the motor 102 and mounted so as not to interfere with the operation of the motor.
In order to provide consistent, reliable motor operating data, the monitor 100 should be capable of withstanding the environmental conditions typically experienced by an electric motor 102, including mechanical shock, temperature, and contamination from such materials as oil and water.
As shown in FIG.
2, the monitor 100 consists of a ruggedized housing 110 capable of withstanding the typically harsh environments of industrial facilities.
Electronics and sensors within the monitor 100 are sealed and protected by the housing 110 so that the monitor 100 may be mounted in exterior and wet environments.
Although the monitor 100 may be attached by any suitable attachment means, including bolts, screws, rivets, quick release fasteners, welding, adhesives, and magnets, a preferred means of attaching the monitor 100 to the motor is shown in FIG.
1.
A mounting plate 106 is secured to the motor frame 104 by bolts (not shown).
Alternatively, the mounting plate 106 is attached to the frame 104 by an epoxy adhesive.
As FIG.
3 illustrates, the mounting plate 106 includes a threaded recess 114 into which a threaded stud 117 is positioned.
The stud 117 is of sufficient length to protrude above the plate 106 as shown.
At the base of the monitor 100 is an engagement surface 116 that includes a threaded recess 119 sized to receive the stud 117
