US Patent:

61777501, Jan 23, 2001

Filed:

Jul 14, 1998

Appl. No.:

9/116135

Inventors:

Edward J. Tompkin - Cuyahoga Falls OH

Assignee:

Reliance Electric Technologies, LLC - Thousand Oaks CA

International Classification:

H02K 128

US Classification:

310261

Abstract:

A shaft or shafts are connected to a rotor core of a dynamoelectric machine without the need for a central hole in the laminations of the core. The shaft is connected to the core by attaching the shaft to a rotor end plate (or forming the shaft and the end plate as a single unit) and connecting the end plate to the core at a distance away from the axis of the core. The rotor may have similar end plates at both ends, the end plates attached to each other and to the core by through studs or bolts that pass through holes in the laminations. The holes and the studs or bolts are evenly circumferentially spaced at a distance from the axis. The through studs or bolts are secured at either end, clamping the end plates with the rotor core between them. The rotor end plate provides support to the rotor end ring that forms part of the squirrel cage of the rotor core. The end plate includes a lip or other portion which restrains movement of the end ring in lateral and/or axial direction(s) as the rotor rotates.

Reliance Electric Industrial Company - Cleveland OH

International Classification:

G08B 2100

US Classification:

34087001

Abstract:

A method and apparatus for real-time electric motor diagnostics and condition monitoring. While the motor is energized, dynamic operating parameters are determined and a notification signed is generated if predetermined criterion are satisfied. The diagnostic apparatus is integrated with the motor and includes a set of sensors, a processing unit, a memory and an output interface for communicating alarms, warnings and calculated operating parameter values or the like to a display device and to an external supervisor having wireless paging capability to alert a remote operator or maintenance personnel. In a normal operating mode, the processing unit calculates a general class of derived motor operating parameters such as over-temperature, over-voltage, over-current, excessive vibration, and phase imbalance. When an abnormal condition is observed, the processing unit modifies certain data acquisition parameters as necessary to effect an alternative data acquisition strategy which would more likely lead to data dispositive of the condition of the motor.

Appl. No.:

9/163111

Carl J. Dister - North Olmsted OH

International Classification:

G01M 1304

US Classification:

73593

Abstract:

A diagnostic system includes a vibration sensor mounted on a machine which has vibration-generating components having different vibration characteristics with respect to a common sensor. The vibration sensor measures vibrations and sends vibration signals to a diagnostic module for evaluation of the signals. The diagnostic module has software for processing the vibration signals. From a known natural frequency of a vibration-generating component, the diagnostic module measures the amplitude of the vibration signal at more than one harmonic frequency of the known natural frequency and compares the amplitudes to amplitudes at adjacent harmonic frequencies. When a relatively large amplitude is found at a harmonic frequency, that is a harmonic frequency near a resonant frequency of the physical path between the vibration sensor and the vibration-generating component, the diagnostic system can then analyze the shape and magnitude of the vibration signal around that harmonic frequency to evaluate whether each of the vibration-generating components is healthy, broken or about to break.
