This pwm motor controller is using the fact that the small dc motor has the revolution speed depending on the power supply voltage. In this circuit the discharge time can be adjusted between 0.2ms and ...

The DC power controller circuit is powered at 12V, regulated down to 8V by IC1 78L08. Capacitors C1, C2 and inductor L1 prevent noise being fed back into the power line when the load is being switched ...

A hydraulic schematic diagram uses lines and symbols to provide a visual display of fluid paths within a hydraulic circuit. A hydraulic schematic also indicates the types and capabilities of ...

If you need to design a control circuit for your FPGA-based DSP system, these simple techniques could save you days of work. By Narinder Lall and Brad Taylor, Xilinx, Inc. August 11, 2006 -- ...

Remember that any and all other devices or control circuits and status indicators may be unaffected and remain energized. This article appeared in the May 2005 issue of Occupational Health & Safety.

Isolating problems in the control circuitIn 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 ...
