直流电机主要分为分为永磁直流电机和电磁直流电机两种类型。其中，永磁直流电机使用永磁体作为励磁源，电磁直流电机则使用电磁体作为励磁源。由于永磁直流电机具有结构简单、效率高等优点，在一些应用场合中得到了广泛的应用。而电磁直流电机则具有转矩大、可靠性好等优点，适用于一些需要大转矩输出的场合。
直流电机的励磁方式主要包括以下几种：
1、永磁励磁：永磁励磁是利用永磁体作为电机的励磁源。这种励磁方式具有结构简单、无需外部电源、效率高等优点。永磁励磁适用于小功率的直流电机。
2、电枢励磁：电枢励磁是利用电枢中的电流产生的磁场作为励磁源。这种励磁方式具有结构简单、容易实现控制等优点。电枢励磁适用于小功率的直流电机，但是效率较低。
3、串励励磁：串励励磁是利用串联在电机电枢回路中的电磁体作为励磁源。这种励磁方式具有转速随负载变化小、启动转矩大等优点。串励励磁适用于大功率、要求转速稳定的直流电机。
4、并励励磁：并励励磁是同时利用串联在电机电枢回路中的电磁体和外部电源作为励磁源。这种励磁方式具有输出转矩大、调速范围宽等优点。并励励磁适用于要求大功率、广泛调速的直流电机。
5、复合励磁：复合励磁是同时采用串励和并励两种励磁方式的组合。这种励磁方式可以兼具串励和并励的优点，可以实现输出转矩大、调速范围宽等特点，适用于一些要求特殊的直流电机应用场合。
