# Maintenance: Create a bulk quote request Introduction to AC Components and Motors In iKnow This is the first lesson in the iKNOW® AC/DC Motor Theory Library. This lesson identifies the components of an AC motor and explains their functions. Basic magnetic principles, sine waves, methods of increasing magnetic flux in a conductor, and how a rotating field is created in an AC Motor are presented. Lever Actuated In iKnow This is the second lesson in the iKNOW Limit Switches Library. This lesson describes limit switches, how they work, how to recognize them, and typical applications they are used in. Advanced AC Motor Principles In iKnow The second lesson in the iKNOW® AC/DC Motor Theory Library, this lesson explains synchronous speed and how to calculate it. The lesson demonstrates the relationship between phased current and rotor spin and induction and its effect on a rotor. Slip and how to calculate slip using its formula are also covered. Torque and Geared In iKnow This is the final lesson in the iKNOW® Limit Switches Library. This lesson describes geared limit switches and torque switches. This lesson also discusses maintenance, troubleshooting, and adjustment requirements for these switches. Solid State In iKnow This is the third lesson in the iKNOW Limit Switches Library. This lesson describes solid state limit switches, how they work, how to recognize them, and typical applications in which they are used. Limit Switches In iKnow This lesson describes limit switches, how they work, how to recognize them, and typical applications they are used in. This lesson discusses maintenance, troubleshooting, and adjustment requirements for the various limit switches. Measurement In iKnow This is the final lesson in the iKNOW Oscilloscopes Library. This lesson teaches how to determine various measurements taken with an oscilloscope. Setup In iKnow This is the seventh lesson in the iKNOW Oscilloscopes Library. This lesson trains the participant to safely setup an oscilloscope for use, how to adjust the controls, and compensate the probe. Waveforms In iKnow This is the eighth lesson in the iKNOW Oscilloscopes Library. This lesson teaches participants to recognize the various waveform types and how to analyze waveforms.
