Compare power tools by brushless motor, smart features and lightweight design to aid product selection.
电动工具升级聚焦无刷电机与轻量化:无刷评分反映效率/寿命,轻量评分反映便携/续航。对比两者给出研发侧重;权重比量化相对占比,辅助技术路线选择。
| Item | Formula / Rule | Source / Standard |
|---|---|---|
| Motor efficiency class | Brushless motors are typically 10% to 20% more efficient than brushed motors, classified into IE efficiency levels. | IEC 60034-30-1:2014, rotating electrical machine efficiency classes |
| Specific power | Specific power = rated output power / tool mass (W/kg), measuring the degree of lightweighting. | IEC 62841-1:2015, electric motor-operated hand-held tools |
| Life cycle assessment | Product comparison must be performed on an equal functional unit basis for environmental impact assessment. | ISO 14040:2006, life cycle assessment principles |
