electrical field energy

Motors have electrical energy supplied to their windings and a magnetic field that develops an electromagnetic interaction to produce mechanical energy or torque.

电能供给电动机绕组和磁场，产生电磁感应作用，试电动机产生机械能或者转矩。

This is an introductory subject in the field of electric power systems and electrical to mechanical energy conversion.

本课程简介有关于电力系统及电机机械之能量转换这两个领域。

However, the average electrical field strength and energy consumption for the maximum enhancement factor for the triangular rod electrode are much lower than for the cylindrical electrode.

在达到最大强化因数时，三角形电极所需要施加的平均电场强度和能耗比圆柱电极低得多。
