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 ...

Microcontrollers may dominate today’s stepper motor projects, but there’s a charm in driving them with pure CMOS logic. Try ...

Part VI of Art. 430 contains modifications of the general requirements and applies to particular conditions of motor control circuits. Motor control circuit conductors (larger than 10 AWG) that extend ...

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 ...

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 ...
