Learners examine an electric motor control circuit that uses a motor starter module. This activity has audio content.

In this simulation activity, procedures are performed to properly align the shaft of an electric motor that replaced a defective motor, with the shaft coupling of a pump to which it is attached.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.

In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.

In this screencast, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.

Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.

Learners use the National Electrical Code to determine the size of a motor overload protection device.

Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.

Learners examine the operation of a DC Shunt motor and its characteristics. A quiz completes the activity.

In this simulation activity, an electrician will troubleshoot an AC motor that quit running and cannot be restarted. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this animated object, learners study the drawbacks of a single-loop armature of a DC motor and the advantages of a multi-loop armature.

Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.

Learners view colorful animations showing the operation of a VR stepper motor.

Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.

The learner will understand the operation of motor control circuits used to start and stop three-phase motors.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

Students view a graphical explanation of how the motor condition (unloaded, 50 percent loaded, fully loaded) affects the phase between voltage and current, the current draw from the AC supply, the amount of power consumed, and the power factor.

Learners examine devices that are used to protect a motor from damage, such as fuses, overload heaters, and thermal protectors. A quiz completes the activity.
