The test sequence. The multimeter shown in the Figure helps depict the troubleshooting steps used to isolate problems in the control circuit. One multimeter test lead (typically the black for ...

With this much productive capacity at stake, proper understanding of motor control is critical. Here are the answers to some frequently asked questions about discrete motor controls. Q. Can you ...

Typical stepper-motor control circuits use either logic gates and flip-flops or shift registers to generate the proper sequences of binary codes that produce bidirectional stepper-motor movement. A ...

The circuit in the figure provides three levels of speed control for a dc motor, using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from the ...
