摘要
三相交流异步电动机绕组的磁势是电动机运行的基础。文章依据理论分析,做出了磁势、磁场及电磁转矩分布曲线。磁势及电磁转矩曲线能形象、直观地反映交流异步电动机磁势、磁场及转矩间的关系,对进一步理解电动机的原理、公式、特性提供帮助。
The magnetomotive force of three-phase AC asynchronous motors is the basis of mortors running. According to the theoretical analysis, the distribution curves of magnetomotive force, magnetic field and electromagnetic torque are made in the paper. These curves can image directly reflect the relationship between magnetomotive force, magnetic field and electromagnetic torque. The help is provided for further understanding the principle, formulas and characteristics of motors.
