Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

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.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

In this animated object, the learner examines 17 types of joint movement.

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.

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.

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.

In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.

In this animated object, learners study the operation of a ladder circuit that controls the rotational direction of a DC motor.

Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

In this animated object, learners identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.
