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!

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 ...

Later, I helped a friend disassemble a Tesla model, and the mass of circuit boards inside was overwhelming—until I drew 5 ...

In this online engineering specialization, you will master sensor and motor theory and program these devices in a microprocessor system. You will complete courses in sensors and sensor circuit design; ...

Another intriguing issue is whether circuits in the remaining frontal agranular cortex—presumably involved in more ‘cognitive’ aspects of motor control—are organized in the form of primary motor ...

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 ...

Guest columnist Alfred Hesener, European marketing director at Fairchild Semiconductor, describes how good design of power switches can help reduce losses in motor control circuits. Energy-saving ...
