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.

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

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

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.

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 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.

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.

Learners examine the connections of a DC motor and how the terminals are labeled. A matching exercise completes the learning object.

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

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

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

Learners consider the changes inside a series motor that could cause it to break apart if the load was disconnected. A quiz completes the activity.

Learners study animation showing the operation of an AC wound-rotor motor with its external starting resistors. A short quiz completes the activity.

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

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.

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 screencast, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
