Technical Description In this study, the electric hand tool machine produced by the brand B of the commercially available electric hand tool machine manufacturer was used, and the internal motor brushless motor was used as a prototype for improvement and optimization.
This study uses the Taguchi method with finite element analysis software to analyze and optimize the motor's stator and rotor details and wire diameters, discuss efficiency, stall torque, harmonics and power density to achieve a full range of high-performance motor designs.
The Taguchi experiment design method uses statistical methods and a concise cross-table test to find out the influencing factors and control factors without complicating a large number of experiments.
Scientific Breakthrough The high-efficiency motors for hand-tool machines developed in this research have a 3.88% increase in efficiency, 70% reduction in cogging torque, 70% reduction in harmonic content, and 26.3% increase in power density, as significant benefits for improving the energy efficiency of the motor and improving the running characteristics.
Industrial Applicability This research focuses on the vibration of electric hand tools during operation and optimizes the motors for high-efficiency hand tools, which can be transferred to production and application in the corporate world, such as: assembly of auto parts, motors, refrigerators, air conditioners, biotechnology and large household appliances, manufacture and assembly of communication cabinet devices, etc.
