Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
Parallel LC Circuit Tic-Tac-Toe 1
By Terry Bartelt
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.
The Counter-Reset Function
Learners examine the counter-reset function of a programmable controller and how it is used.
Ignition System of a Combustion Engine
Students view the parts and movements of a combustion engine in this animated activity. Each part is described.
Series RC Circuit Practice Problems
By James Bourassa, John Rosz
In this interactive object, students calculate capacitive reactance, phase angle, impedance, and power in series RC circuits.
RPM of AC Motors
Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.
The Three-Phase Motor Stator Field
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.
The Multi-Loop Armature of a DC Motor
In this animated object, learners study the drawbacks of a single-loop armature of a DC motor and the advantages of a multi-loop armature.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
Armature Action of AC Motors
In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.
