Learners read a description of torque and study the factors that cause its magnitude to change.

In this animated and interactive object, learners examine the formula for horsepower and work practice problems.

The learner will examine how torque is developed in an induction motor.

The learner will understand the two methods used to create a phase shift in current between two windings.

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.

Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.

Learners view an animated explanation of why an adjustment of the output voltage by an AC drive is required to maintain a constant torque as the frequency is varied.
