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.

The learner will gain an understanding of the inner workings of the cycloidal gear drive while watching a video and listening to an explanation of its features.

The learner will understand the design of a planetary gear drive and its advantages and disadvantages.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.

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.

Students follow steps to determine the number of inputs that can be driven by a specific IC. A sample problem is given.

Learners consider the most common types of electromagnetic waves and the kinds of hardware used in a wireless network. A short quiz completes the activity.

In this simulation, you’ll learn to differentiate between basic deletion and secure erasure to protect sensitive information.

Learners listen to an explanation of how to perform an inventory of a farm business. They then list their hard assets and human resources by completing worksheets that they save to their personal computers.

Learners will understand how binary-coded decimal information is decoded and used to drive a seven-segment display.

In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

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 scenario, learners take the role of a delivery driver who must find a new travel route after the Interstate is closed to trucks. “Drivers” listen to traffic reports and write directions for a new route. This activity has audio content.

In this animated activity, learners examine the circuitry in a DC variable speed drive that causes the motor to accelerate or decelerate at slow rates. This learning object has audio content.

In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.

In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

In this animated and interactive object, learners examine why the voltage produced by an AC drive must be increased when its frequency is increased due to inductive reactance.

Learners consider the correct type of pushbutton to use as a Stop button, the way the Stop button should be hard wired, and the PLC input instruction to use. This animated object includes a short quiz. It is recommended that learners review the learning object “The PLC Examine-Off Instruction” before beginning this object.
