When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Symbols and Diagrams for Motors introduces different diagrams used to represent motor circuits and symbols that circuit diagrams commonly contain. Pictorial diagrams are the simplest and use ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

In order for the solenoid point motor to throw the point we need to apply current briefly to an electromagnetic coil. A capacitor discharge unit greatly improves reliability in that it builds up and ...

The PCA146x series devices are CMOS integrated circuits specially suited for battery-operated, quartz-crystal-controlled wrist-watches, with a bipolar stepping motor. The motor output delivers pulses ...

Explains electric current, highlighting that it originates from a battery and requires a complete circuit to flow. It compares electric current to water flowing through pipes, using meters to ...

Ever found yourself tangled in a mess of wires and components, struggling to create a clear and intuitive wiring diagram? If so, you’re not alone. Many electronics enthusiasts face this challenge, ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...
