In-Situ Monitoring of the Brush/Rotor Interface in a Homopolar Motor with Acoustic Emission
Homopolar motors have been proposed as an alternative propulsion means for ships. Such motors operate in a very harsh and demanding environment, making in-situ diagnostics and faultmonitoring systems a key issue for extended operation. In a typical homopolar motor, several thousand brushes are used, which are all in sliding contact with a copper rotor at a velocity of about 10 m/s. Wear and deg...
متن کاملDouble Layer Magnet Design Technique for Cogging Torque Reduction of Dual Rotor Single Stator Axial Flux Brushless DC Motor
Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors. This paper presents a double-layer magnet design technique for cogging torque reduction of axial flux permanent magnet motor. Initially, 250 W, 150 rpm axial flux brus...
متن کاملA study of the brush/rotor interface of a homopolar motor using acoustic emission
Acoustic emission transducers were used to study the brush/rotor interface of a homopolar motor as a function of design parameters such as speed and load. The results indicate that acoustic emission is well suited for in situ monitoring of brush wear and rotor conditions, and for analyzing the tribological phenomena occurring at the brush/rotor interface. r 2007 Elsevier Ltd.
