Abstract

This paper introduces an electric gear to run a high speed spindle motor. Compared with inverter driving, electric gear can be used to reduce switching loss caused by using high switching frequency and improve heating problem on reactor with sinusoidal current wave form. In this paper advantages and disadvantages of electric gear are presented in comparison with those of inverter driving and mechanical gear, and its usefulness is verified by means of experimental approach.
