内容简介
1.内容系统全面,基本上涵盖了目前常见的各种电机和基本控制方法。本书从磁路和磁性材料开始讲起,不但介绍了传统的变压器和旋转电机,还涉及了机电能量转换原理、永磁电机、单相感应电机、开关磁阻电机、直线电机、电力电子技术介绍、电机的速度与转矩控制等内容。
2.内容编排方式与常见的电机学教材不同。例如,在介绍旋转电机之前,先比较详细地介绍了机电能量转换原理;然后对旋转电机的共同问题(磁动势、电动势、电磁转矩等)统一进行介绍;最后再分别说明各类电机的特性。
5.注重概念方法。从内容的整体编排到具体内容的叙述,都体现了突出电机学的物理概念、强调电机学基本分析方法的指导思想。为避免读者陷入复杂的数学计算中,还引入了Matlab作为辅助的计算工具。全书思路清晰,文字严谨流畅,清楚易懂。
4.理论联系实际。书中采用了许多实物的图片,并在附录中专门介绍了一些电机工程实际问题。这样可使读者比较清楚地了解电机理论与实际电机间的对应关系,有助于对基本原理和概念的理解。
5.例题习题丰富。作者或者通过例题对前面内容做进一步的解释,或者直接把例题本身作为对基本概念和原理的带有定量计算的说明,使例题和其他内容有机地融为一体。
