A Stability Model for Flexible Rotors With Magnetic Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A direct linear modeling scheme is described for magnetic bearing supported rotors. The model includes the effect of controller bandwidth as well as sensor-actuator noncollocation. These effects, ...
Magnetic Bearing Sizing for Flexible Rotors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetic bearing load capacity in flexible rotor systems must be adequate to accommodate external loads acting on the rotor. The first part of this paper develops the theoretical basis for ...
Optimization of Bearing Locations for Rotor Systems With Magnetic Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a method for quickly evaluating the effect of changes in bearing location on bearing design for stability of rotating machinery. This method is intended for use by rotating ...
Force Versus Current and Air Gap Calibration of a Double Acting Magnetic Thrust Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Force versus current and air gap measurements were obtained for the actuator component of a double acting magnetic thrust bearing constructed from a powdered metal. Static force measurements ...
Reconciliation of Rotordynamic Models With Experimental Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computationally efficient strategy is presented for adjusting analytic rotordynamic models to make them consistent with experimental data. The approach permits use of conventional rotordynamic ...
Magnetic Bearing Design for Reduced Power Consumption
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetic bearings have relatively low power consumption compared to fluid film and rolling element bearings. They are now candidates for supporting gas turbines and aeropropulsion engines. This ...
Measured Force/Current Relations in Solid Magnetic Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When magnetic bearings are employed in a pump, compressor, turbine, or other rotating machine, measurement of the current in the bearing coils provides knowledge of the forces imposed on the ...
Magnetic Thrust Bearing Operation and Industrial Pump Application
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetic bearings represent a new bearing technology, which has some advantages over conventional fluid film and wiling element bearings for some applications. The paper describes the basic ...
