The Three-Phase Motor Stator Field
By Terry Bartelt
In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.
Voltage and Current Amplitudes in a Parallel LC Circuit
In this interactive object, learners examine how voltages and currents vary in a parallel LC circuit as the applied frequency changes.
By Terry Bartelt, Pat Jensen
Learners examine devices that are used to protect a motor from damage, such as fuses, overload heaters, and thermal protectors. A quiz completes the activity.
