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

Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.

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.

Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.

In this animated object, learners study what happens if the maximum switching speed of a proximity sensor is exceeded.

Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.

Learners identify the advantages and disadvantages of four versions of high speed Ethernet. A short quiz completes the activity.
