In this screencast, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
