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.
Using the Microstepping Technique for Stepper Motors
Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.
Single-Phase Motors: Introduction to Phase-Splitting
Learners will understand how the interaction of the armature magnetic field and the rotating stator field cause the rotor of a single-phase AC motor to turn.
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
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.
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.
Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.
Learners answer questions about internal combustion engines using a game board format. This learning object can be used individually, in small groups, or as a class activity to provide an alternative self-assessment tool.
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.
