Learners use the National Electrical Code to determine the size of a motor overload protection device.
By Terry Bartelt
Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.
Reversing the Rotation of DC Motors
By Terry Bartelt, Terry Fleischman
Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.
The Transistor Symbol
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
Series Circuit Analysis Practice Problems: Circuit #3
By Patrick Hoppe
In this interactive object, learners solve for the current through each resistor, the voltage across each resistor, and the power dissipated.
Calculating Horsepower, RPM, and Torque
By James Bourassa, John Rosz
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
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 DC Shunt Motor
Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.
Motor Control Circuits
Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.
High-Low Speed Drive Adjustments
Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.
