Water-Cooled Direct Drive Permanent Magnet Motor Design in Consideration of its Efficiency and Structural Strength
Journal of Magnetics, Volume 18, Number 2, 30 Jun 2013, Pages 125-129
Abstract
This paper deals with a water-cooled direct drive permanent magnet (DD-PM) motor design for an injectionmolding application. In order to meet the requirements for the target application and consider the practical problems of the manufacturing industry, the DD-PM motor is designed in consideration of efficiency and structural strength with many constraints. The performances of the designed motor are estimated not only by magnetic field analysis, but also by thermal and structural analysis. The design and analysis results are presented with experiment results.
Keywords: motor design; permanent magnet; structural strength; thermal analysis; water-cooling
