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.

In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
Converting Rotational Velocity to Linear Velocity
By James Bourassa, John Rosz
In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
Voltage Sources in Series
In this learning activity you'll explore the effect of connecting voltage sources in series to increase voltage applied to a load.
Motor Action (Screencast)
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.
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.
The Induction Motor Slip
By Terry Bartelt, Terry Fleischman
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
