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 ...

This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

Groomed for use in small-motor control circuits, the HSF series surface-mount, surge resistor exploits a cylindrical design to aid heat dissipation and produce higher surge/pulse capabilities than ...

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; ...

Motor control and drives are fundamental in many applications, as they allow a high degree of accuracy, which in turn translates into lower costs and greater efficiency. The vital function performed ...

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 ...

When designing a motor control circuit, it’s vital to determine how to deliver the high current required to drive the motor. Designers must choose whether to use monolithic integrated circuits (ICs) ...

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!
