The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Sine-wave oscillators such as the Wien-bridge, state-variable, or quadrature oscillators, have an inherently undefined amplitude. Ideally, the poles of their feedback loop are on the jω-axis and the ...

Electronic Fuel Injection (EFI) is a solution that guarantees a low emission as well as a fuel consumption optimization, for small motors that, otherwise, can be very polluting. This fact underlines ...

ANSI/ISA-112.00.01-2025, SCADA Systems – Part 1: SCADA Lifecycle, Diagrams and Terminology, provides a vendor-neutral, practical framework for managing supervisory control and data acquisition (SCADA) ...

The ISA88 standards committee, Batch Control, will soon begin work in concert with IEC SC65A on an update of Batch Control Part 1: Models and Terminology. The standard, last published as ...

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 ...
