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 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 examine the circuitry in a DC variable speed drive that protects the rectifier diodes and motor windings from being damaged due to excessive current.
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 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.
Using Blueprints to Troubleshoot a Defective Compressor Motor
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.
Troubleshooting a Three Phase Motor that is Overheating
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 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.
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 and interactive object, learners examine the inverse proportionality of wavelength and frequency and their relationship to the speed of light.
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
