Analytical Calculation of Magnetic Field Distribution in Coaxial Magnetic Gears
Coaxial magnetic gears are a new breed of magnetic devices, which utilize the interaction of permanent magnet fields to enable torque transmission. Apart from using a numerical approach for their magnetic field analysis, an analytical approach is highly desirable since it can provide an insightful knowledge for design and optimization. In this paper, a new analytical approach is proposed to cal...
متن کاملGearbox Fault Detection Nrel Gearbox Test Facility
the winD inDustry has experienceD a rapid expansion. As wind farms are aging, their operations and maintenance issues are gaining in significance. The wind industry has been affected by failures of wind turbine components such as main bearings, gearboxes, and generators. Replacement of failed components results in the high cost in energy production. Therefore, research in fault identification a...
متن کاملFunctional Tolerancing of a Gearbox
This paper proposes a scheme for the tolerance specification that uses the features’ function information and mating condition attributes in the assembly to derive an appropriate tolerance specification as per the design intents. The proposed mirror method provides a way to locate the critical components. It helps the user identify functional features and group them into clusters. Temporary DRF...
متن کاملMagnetic Field Equivalent Current Analysis-Based Radial Force Control for Bearingless Permanent Magnet Synchronous Motors
Bearingless permanent magnet synchronous motors (BPMSMs), with all advantages of permanent magnet motors (PMSMs) and magnetic bearings, have become an important research direction in the bearingless motor field. To realize a stable suspension for the BPMSM, accurate decoupling control between the electromagnetic torque and radial suspension force is indispensable. In this paper, a concise and r...
متن کاملReluctance Force Magnetic Suspension Characteristics and Control for Cylindrical Rotor Bearingless Motors
In this paper, the modeling and control of reluctance-force-based magnetic suspension in cylindrical rotor, ring-shape air gap, bearingless motors are presented. The full suspension system dynamics, including both the destabilizing force due to the motor field and the active magnetic suspension control forces, are modeled, and a transfer function of the bearingless motor suspension plant is der...
