Performance verification of a high speed motor-generator for a microturbine generator

摘要

The Research Institute is developing a motor-generator that fits into a microturbine generator (MTG) system with a power density of 500W. This paper introduces the design, analysis, production and assessment of the heart of an MTG system, the motor-generator, whereby an amorphous core is applied creatively to a stator core. The motor-generator is designed and analyzed with consideration to losses and the circuit by magnetic analysis. The centrifugal force analysis is performed for the static stability, and rotor dynamics is performed for dynamic stability at high speed. Back-to-back tests are done to assess the power generation characteristic of the motor-generator. The noise, vibration, and the internal temperature of the motor-generator are considered. Based on these results, a high speed motor-generator is successfully developed.
