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.
Basic Elements of Dimensions Used in Engineering Drawings
By Glenn Sokolowski
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
Designing a Ladder Diagram
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
GD&T: Geometric Characteristic Symbols
In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.
By Terry Bartelt
In this animated object, learners examine how PLC up/down-counters are used to control an automated parking lot gate.
The Dial Caliper
By Barbara Anderegg
Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.
An Inductor Opposing a Current Change
Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.
