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.
By Terry Bartelt, Terry Fleischman
In this animated object, learners study how the internal parts of an AC synchronous motor interact with magnetic fields to cause rotation. A short quiz completes the activity.
Designing a Reciprocation Circuit
By Terry Bartelt
This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.
The TI-86 Scientific Calculator: The Editing Functions
By Patrick Hoppe
Students read about the ENTRY, INS, and DEL keys and view a demonstration of how to edit and insert characters and recall previous entries.
Statics - Trig: Law of Cosines Using a TI-86 Calculator
By Steve Whitmoyer
In this interactive and animated object, learners apply the Law of Cosines to determine forces using a TI-86 calculator.
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
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.
