DC Motors and Generators,rical energy (generators). The first usable motors and generators got their start in the mid to late 1800s and have served as the backbone of the modern industry ever since. In this chapter, we will cover the basics of direct current (DC) motors and generators. The analysis will assume steady-state

Phasor-Domain Power Analysis,ey differences. First, since the voltages and currents vary with respect to time, the power flow will also vary over time. Therefore, the time-average power flow is of greatest interest when assessing efficiency. Second, rather than having just one power term, the flow of energy associated with the
